5 Ways To Prevent Computer Vision Syndrome, Especially While Working From Home

As the number of people functioning from home continues to rise, so does the amount of time working remotely at a computer screen. The extra time spent on a computer, whether it is a desktop, tablet computer, e-reader or mobile phone, is creating extra potential for eye related problems. This can cause what is referred to as Computer Vision Syndrome or CVS. An improperly located device can trigger CVS, causing eye dryness, inflammation, a loss of focus and also a general adverse impact on work performance. This happens for several reasons. First, considerable muscle effort is needed to sustain clear vision at close working distances. Over hours, the vision system experiences muscle tiredness. Secondly, sustained close work also demands tremendously focused attention and can lead to perceptual tunnelling that enhances distractibility as well as reduces attention span.

Lastly, anyone working at a computer system has impaired blink function. The blink generates moisture and is an essential part of how the eye takes care of itself. Normal blinking takes place about 15 times per minute. Nevertheless, research studies show blinking just takes place about 5 to 7 times per minute while using computers and other digital screen devices. Much less moisture on the eye’s surface can cause blurring of vision, watering, and also burning of the eyes.
Right here then are 5 methods to deal with CVS and maintain ideal eye health.

1. Place the viewable area of the display screen a little below the line of sight

Assuming excellent ergonomics at the desk and chair, the computer system needs to be positioned for a slightly downward gaze. The slightly downward gaze is much easier on the eye than looking straight forward or viewing upwards. It helps bring the eyelids down and helps remove the chances of being affected by drafts, particularly when a cooling unit is positioned in the same space. It helps safeguard against dryness. Additionally, correct screen placement promotes good posture with both feet flat on the floor.

2. Eliminate or decrease screen glare

Light induced toxicity or discomfort in your eyes can result from too much glare, even impairing clear vision. It can affect one’s ability to carry out their normal job function. A good test is to place a folder over your head as you view your work terminal. If it is simpler to read with the folder than without it, the user may have issues with discomfort as well as disability glare.
Glare can be reduced by positioning a screen on the computer monitor. Anti-glare coating on eyeglasses can additionally help.

3. Lessen direct exposure to blue light

As computers end up being a lot more modern as well as sophisticated, so does exposure to blue light. This type of light has immediate consequences consisting of effect on long-term macular health, the part of the eye that processes 20-20 vision. Additionally, blue light can hinder the sleep cycle. Filters as well as screens can help in reducing blue light exposure.

4. Permit workstations to allow peripheral vision

Workstations must be built to permit ambient visual stimulation or eye activity taking place in the field of vision. Vision performs best when it is exposed to a full range of visual stmulation, not simply one type while blocked from seeing others.

5. Take breaks

To ideally protect against computer related eye strain, users need to maintain mindfulness about blinking, position screens in the right space, avoid multiple screens, as well as take breaks. Getting up, walking around, and maybe light stretching or rotation of the arms, wrists, neck, as well as back, will certainly help minimize a high level of eye stress and strain and ensure a more productive work experience.

A Complete Guide of Intraocular Lenses

An intraocular lens is implanted in the eye when your all-natural lens which has actually turned opaque because of the advent of cataract, to restore your vision to ideal. With advances in available technology for cataract surgical procedure, improving and making it convenient and a day-care surgery without any hospitalization, the types of intraocular lenses, called IOLs, have actually also undertaken a revolutionary change, making vision correction simpler and more convenient. The very first IOL that was implanted in the human eye, was made from an acrylic material called Perspex.
Intraocular lenses were accepted as “safe as well as effective” in the UNITED STATES by the Food and Drug Administration (USFDA) only in 1981. From then to currently, the type of lenses that are readily available for implantation has been absolutely nothing short of a revolution for cataracts treatment.

Types of Intraocular Lenses (IOLs)
Two most common kinds of lenses are:

1. Anterior Chamber Intraocular Lenses (ACIOL): These lenses are positioned on top of the iris, the brown part of the eye. It is not the physical position of the all-natural lens of the eye, and this type of lens is not the usual choice IOL after non-complicated cataract surgical treatment. ACIOLs are implanted in case the posterior capsule of the lens is deficient or damaged and are specifically prescribed by eye doctors only in such cases.

2. Posterior Chamber Intraocular Lenses (PCIOL): These lenses are put into place over the residual posterior capsule in the same physiological placement as the all-natural lens of the eye and also are the recommended lenses, which are normally recommended for otherwise healthy eyes.
The remainder of this post will discuss the important types of advanced PCIOLs available for implantation after current-day cataract surgical procedure, specifically, phaco-emulsification, Micro-incision cataract surgical treatment or Femto-second laser cataract surgery. These lenses are jointly called premium IOLs.

Types of Premium IOLs
Premium IOLs are of three broad classifications:

1. Mono-focal Lenses
Mono-focal lenses, unlike the natural lens of the eye, can just restore vision for one range, that is for distance, or for near. The power of the mono-focal lenses is usually computed to ensure that the patient does not need glasses for distance vision. After having a mono-focal lens implantation, you will need reading glasses or even bifocals which are eyeglasses for both distance and near, thus not completely eliminating the need for eyeglasses, depending upon your pre-existing refractive error (specifically astigmatism). Below are the various types of mono-focal lenses:
– Aurium (Mono-focal): Aurium monofocal lenses are photo-chromatic, which means they come to be slightly tinted during daytime or bright light and also therefore protect against unsafe UV. Under regular room lighting conditions, these lenses end up being clear.
– Acrysof INTELLIGENCE (Monofocal): Acrysof IQ is a mono-focal lens which provides great vision for distance. For near vision, nonetheless, an individual may need extra reading glasses. This lens includes a yellow pigment chromate-phore which blocks harmful UV rays and also blue light from entering the eye as well as harming the retina.
– Aurovue (Mono-focal): Aurovue lenses are considered as entry-level alternatives for cataract surgical treatment as well as are recommended for somebody on a lower budget plan.
– Akreos AO (Mono-focal): Akreos AO resemble Aurovue lenses.

– Acrysof SP (Monofocal): Acrysof SP is a monofocal lens which is are extra favoured in Diabetic Patients. It is also an advised alternative for somebody selecting a mono-focal lens in Regular Phaco surgical procedure.

2. Multifocal Lenses
Multifocal IOLs are lenses which offer an acceptable restoration of vision for both near and distance and not just either like momofocals. While choosing an IOL, it is essential to keep in mind that multifocal lenses provide you independence from glasses for both near and distance, and also can be personalized to your active life-style. Nonetheless, your doctor will certainly discuss with you the apparent disadvantages of these lenses, particularly glare, and also a decrease in contrast sensitivity. In case you do not intend to put on glasses for near or distance and do not wish to proceed with the added expense of a multifocal IOL, your eye doctor will certainly consider mono-vision with you. Following are the most effective multifocal lenses:
– Tecnis Harmony (Multifocal): Tecnis Harmony is a multifocal lens that offers superb distance and intermediate vision (for computer work).

– Zeiss Trifocal (Multifocal): Zeiss trifocal lenses are multifocal type lenses which are the only lenses which give excellent vision for near, intermediate and distance, all three ranges at the same time like progressive lenses in eyeglasses.

– iDiff (Multifocal): iDiff lenses are multifocal lenses that provide good vision for near and distance, which implies that a person can conveniently carry out regular daily tasks with distance vision and also do near work such as reading as well as writing easily without use of additional eyeglasses. iDiff Lenses, nevertheless, do not provide appropriate intermediate vision.

– Tridiff (Multifocal): Tridiff lenses are multifocal lenses which offer good vision for near, intermediate and distance, which implies that an individual can quickly perform routine day to day activities with distance vision, additionally do intermediate distance tasks such as working on the laptop and also complete near tasks such as reading as well as writing easily without the use of extra eyeglasses.
– Alcon Pantopix (Multifocal): It is the biggest innovation in multi-focal lenses. The lens has the ability to provide outstanding vision for distance, intermediate as well as near.

3. Toric Lenses
An eye can have two kinds of power, spherical power which is because of the natural lens within the eye as well as cylinder power which is because of the dissymmetry in the curvature of the cornea. Mono-focal and Multifocal Lenses can just correct the spherical component of the refractive error leaving behind the cylinder power which needs to be later corrected by additional prescription glasses, reducing the benefits of the lens implant. Toric Lenses can deal with both spherical as well as cylinder parts of the eye prescription. Toric lenses are advised if you have a high pre-existing cylinder or astigmatism in your eye. Below are the recommended Toric lenses:
– Acrysof IQ (Toric): These lenses are designed to correct astigmatism at the time of cataract surgery.

– Acrysof Toric (Toric): These lenses have all the properties of Acrysof IQ in addition to cylinder improvement.

– Zeiss (Toric): The lens is among the benchmarks in premium cylinder correction.

Which is the most effective IOL for you?
In medicine, like life, there is no single best solution. Your eye doctor will discuss with you the possible benefits of each of these lenses, and help you pick the one, best fit for your lifestyle and vision needs, along with your expectations from cataract surgery.
Lifestyle and priorities: In case you have an extremely active lifestyle that entails a lot of precise focusing outdoors, like playing golf, you might endanger your near vision however not your distance vision. If you travel a lot, you might prefer to not depend on glasses at all, sacrifcing a little accuracy for both near as well as distance vision. On the other hand, if you take pleasure in stitching or needlework, you will desire good near vision.
Pre-existing illnesses: In case of certain eye conditions like advanced glaucoma, corneal disease or age-related macular degeneration, you may not be an excellent prospect for certain lenses, like the multifocal lens. Your ophthalmologist will certainly carry out a thorough eye examination as well as discuss its outcomes as well as implications with you, to assist you choose the most effective and feasible lens for your eye.
Prices: These lenses are a lot more pricey than standard IOLs, adding an incremental value to the cost of cataract surgery. The premium lenses come with a price that is normally not covered by insurance companies.
The eye doctors at Khanna Vision Institute are well versed in using premium IOLs following cataract surgery in CA and also have had the experience of implanting hundreds of these lenses. Our optometrist will be more than happy to go over all the choices readily available and help you pick the best option for your eye health, and also vision needs.

Down Syndrome & Vision

Down syndrome has effects on the developing eye which can impact the appropriate development of vision. Eye disorders or problems are reported in over half of patients with Down syndrome, varying from much less serious problems such as tear duct abnormalities to vision threatening diagnoses such as early age cataracts. Specific emphasis ought to be provided to vision issues in patients with Down syndrome.

What is different about the Eyes in Patients with Down syndrome?

As any relative/guardian of a patient with Down syndrome recognizes, there are characteristic features about the eyes. This includes upward slanting of the eyelids, noticeable folds of skin between the eye and the nose, and little white spots existing on the iris (the colored part of the eye) called Brushfield’s areas. These spots are harmless, and also can be seen in patients without Down syndrome

Do Most Kids with Down Disorder Need Glasses?
Refractive error (the need for glasses) is much more common in youngsters with Down syndrome than in the general populace. This refractive error can be hyperopia (farsightedness), astigmatism, or near-sightedness (myopia. One more issue is weak accommodation (trouble changing the focusing power of the eye from distance to near). This can be checked this easily in the clinic, and also if found, eyeglasses that are bifocal can be recommended. Some patients have trouble getting used to glasses, but once they get accustomed to having the eyeglasses on their face, their vision is dramatically better as well as usually their eye alignment improves also.

What common, but Less Significant, Eye Abnormalities Affect Patients with Down syndrome?
Along with the need for spectacles, several children with Down syndrome have tear duct problems. Members of the family will find this as a regular discharge and tearing from the eyes, worsened by colds. Usually, firm massage is recommended over the space between the eye and the nose (tear cavity region) 2-3 times a day to attempt to open up the tear duct. If this continues beyond a year of age, the tear ducts might require to be opened up by a surgical procedure.
Strabismus (eye misalignment) is likewise a lot more usual. Members of the family might observe that the eyes do not line up well with each other, but usually the strabismus can be subtle, also to the paediatrician. The folds of skin stated above, between the eyes as well as the nose can also conceal the underlying strabismus, or make the eyes look like if they are crossing even if they are not. It is important to diagnose strabismus or cross eyes or misaligned eyes as a child, as cross eyes can result in more serious vision threatening problems like amblyopia (loss of vision also referred to as lazy eye) and loss of stereopsis (using the two eyes together, or depth perception).

Exactly how can the Strabismus be treated?
Occasionally, just eyeglasses alone are enough to align eyes with strabismus. If glasses are needed, doctors always start there. If the eyes continue to have strabismus in spite of the appropriate set of glasses, then strabismus surgical treatment (eye muscle surgery) is recommended. This is a one to two hours treatment, which can commonly be done as an outpatient treatment unless there are other factors due to which the patient would certainly require to be admitted, such as a serious heart disease. Unfortunately, patients with Down syndrome are more likely to call for more than one surgical procedure to straighten their eyes as they don’t always react as predictably to strabismus surgical treatment as the general populace with strabismus would.

What are the more serious eye problems that might develop?
The biggest concern is congenital cataracts (absence of clearness in the lens of the eye). If visually significant cataracts are present early in a child’s eye, then a clear image is not provided to the brain and therefore the mind can never “learn” to see. This is a serious kind of amblyopia called deprivational amblyopia. While we may not immediately need to get rid of a cataract in an adult patient and can wait to let it develop fully, as opposed in a child significant cataract need to be removed immediately otherwise, they may cause poor vision or even loss of vision. In that situation, even if the cataract is removed when the child is older, the vision never ever improves significantly. This is what makes very early discovery of cataracts in infants and youngsters so essential. A child with Down syndrome will be evaluated by the doctor at birth, and referred to an eye doctor if something unusual is detected. There is additionally a distinct kind of cataract in Down syndrome patients that have actually been found in research. Nevertheless, depending upon exactly how developmentally delayed the patient is, they might not have the ability to communicate that they cannot see. For this reason, any type of patient with Down syndrome, who is recommend to an eye doctor, no matter at what age, a complete eye assessment is done if they are beginning to show lowered cognitive function, or they show changes in their normal activities.

What other Eye Issues exist in Down syndrome That Can Cause Loss of vision?
As earlier pointed out, one is amblyopia (generally called “lazy eye” which is lowered vision) which can be caused by various different eye problems such as strabismus, extreme ptosis (eyelid droop), cataracts, or perhaps uncorrected refractive errors, especially if one eye needs a much more powerful eyeglass prescription than the other. Ptosis is generally simpler to appreciate but strabismus as well as substantial refractive error can be extremely difficult for the paediatrician to detect. There are other additional rare issues which can occur with the optic nerve or retina of the eye which can often cause vision loss as well as unfortunately, are usually not treatable. Nystagmus (a rhythmic shaking of the eyes) can also occur.

What is the Recommended Eye care for children with Down syndrome?
The American Academy of Pediatric Medicine (AAP) and also the Down Syndrome Medical Interest Group (DSMIG) suggest analysis of the red reflex of the eyes at birth to look for cataracts, in addition to evaluating the eyes for strabismus or nystagmus. The red reflex is basically the “red eye” seen in digital photography, which is the typical reflex of the retina when struck by straight light. If the eyes don’t look normal, then the child/baby should be referred to a paediatric ophthalmologist – a doctor that has actually completed specialized training in clinical and surgical monitoring of the children’s eyes. It is usually recommended that a child with Down syndrome has their very first eye examination by an eye doctor experienced in people with special disabilities (for example, a paediatric eye doctor), when six months old. Afterwards, children with Down syndrome, even if they lack symptoms, ought to see an eye doctor every one to 2 years. If any kind of eye problems is found, they should be certainly followed up more frequently.

What Sort of symptoms might we see if a child has an Eye problem?
Regrettably, children with Down syndrome typically do not complain about their eye issues, either since they do not notice the issue or due to the fact that they cannot connect the issue well enough. Indications to look for include squinting or shutting one eye closed, an unusual head tilt, crossing or wandering of one or both eyes, or light sensitivity. In some severe instances, the indicator of vision problems might be a regression in overall function or loss of developmental milestones. Ptosis will certainly be seen as an eyelid droop, and a blocked tear duct will result in daily tearing and discharge.

Any thoughts for Moms and Dads of a child with Down Disorder Who Are Concerned About their child’s eyes or vision?
Getting routine eye examinations done is really essential in children with Down syndrome due to the fact that eye disorders are so usual and also are tough for the doctor to diagnose. Because the examination can be tough for both the youngster and the eye doctor, it is best to actually have the assessment done by an eye doctor skilled in handling children with developmental delays. Do not be surprised to discover your child needs glasses; and if needed, the glasses will certainly help with vision, and potentially the eye alignment, in addition to helping in the development of normal vision pathways in the brain. This will help with your child’s learning as well as working. Many research studies are looking at simply how usual eye problems are in Down syndrome, as well as the progression of cataracts in these patients.

The elephant nose fish is native to Africa as well as has actually uniquely shaped eyes to help them see clearly at night and in muddy water.

Drug-Delivery Contact Lenses
Eye drops can be difficult to use, irritate the eye as well as in many cases create adverse effects. Frequently, only a small amount of the eye drops are actually absorbed through the eye, in some cases just 5%. The pain and also difficulty of this triggers a lot of patients not to utilize the eye drops as typically as they should. Drug-delivery contact lenses are the excellent choice.
These smart contact lenses can provide medicine to the eye progressively in time. In addition to improved application compared to eye drops, this technique improves the speed and also the amount of medicine that is dispensed to the eye with little to no negative effects. These lenses would certainly be helpful to patients with dry eye problems as well as glaucoma, but it could also serve to assist patients recover post-surgery.

Thermal Vision Lenses
Programmers say maybe it may be feasible to place thermal vision technology right into contact lenses. This technology would certainly permit soldiers to see much better in the the dark, enabling them to spot human beings, animals and devices like smart phones with the heat they produce. Although there are infrared detectors already in operation, these thermal contact lenses would get rid of the need for lugging around huge and cumbersome cooling equipment.

Modern silicone hydrogel lenses do not rely on the water content for oxygen transmission or permeability through the lenses, ensuring your cornea still gets as much oxygen after a day at the desktop computer as it did when you placed the lenses in your eyes, when beginning your day. And it can be a lot comfier for many patients.
Likewise, if you work in front of a computer system all day as well as wear contacts, keep in mind to blink regularly! Practice the 20-20-20 Rule: every 20 minutes, look away from your monitor and also focus on something at the very least, 20 feet away, for 20 seconds. Your eyes will certainly thank you for this.

8. Discretion
Not comfortable putting on glasses? Get a clear vision with a distinct look – no one will discover that you wear contacts!
And patients with high prescriptions do not require to bother with thick, pop bottle lenses like they do with glasses. A high prescription in the form of a contact lens isn’t visible to anyone else. And also, it does away with much of the curvature and also distortion that goes together with solid spectacle lenses.

9. Keep Your Field Of Vision Clear
Last but not least, with contact lenses your field of vision isn’t limited to the limits of your eyeglasses frame! With contacts, you can step out as well as see the entire world clearly again and again, without the peripheral barrier of a bulky frame. With appropriate contact lens wear, you can delight in a much wider line of vision.

Interested to Experience Contact Lenses?
Glasses or contact lenses? The best alternative is to discuss it with your eye doctor or ophthalmologist to choose what the suitable option is for you. Spectacles will always stay a great choice if you put on contacts however, want to take them off once in a while. Glasses cannot be replaced by contacts entirely; they’ll always be a good supplement to contact lenses and the other way around.
The advantages and disadvantages of contacts vs glasses could be discussed for a very long time. What is essential though is for you to find the excellent match for your vision as well as comfort! We provide a large range of contact lenses for all types of vision problems.

What Is an Intraocular Lens Implant?

An intraocular lens implant is a synthetic replacement for the natural lens of your eye. It becomes part of the surgical procedure to repair cataracts which is the removal of the aged, cloudy lens with an artificial replacement or implanted lens.

How your Eye Functions
Each eye has a lens – a window constructed from clear protein as well as water that sits behind the pupil. The lens concentrates light onto the retina, which sends the image formed to your brain in the form of nerve signals.
As you age, the healthy proteins changes and parts of your lens turn cloudy. This is known as a cataract. It can make objects look fuzzy or give them a brownish tint.
Cataracts are a leading source of loss of sight, particularly in older people. Yet they can be fixed via surgical procedure – a treatment that’s done more than 2 million times a year in the USA.

The Implant
An intraocular lens implant (IOL), is made from a clear plastic, as well as it’s about a third the size of a cent. There are numerous different types as follows:

Monofocal IOL: This is the most usual. Unlike your all-natural lens, which can stretch or flex to assist your eye focus, this implant keeps focused at one fixed range. If you focus at a distance, you may be able to see objects that are far, however you may need glasses to read or see close.

Multifocal implant: Like glasses with bifocal or progressive lenses, this lens has zones that help you see objects at various distances. It might take a number of months for your brain to adapt so your vision seems natural. It can sometimes create even more halos or glare around lights than a mono-focal lens.

Accommodating IOLs: This versatile choice of lens acts more like your natural lens, and also focuses at more than one distance. It makes you less likely to require reading glasses.
Toric IOL: You’ll get this implant if you have astigmatism, or a cornea that’s more football-shaped than round or irregular shaped. This can make vision hazy all around, not just close up or far. This lens decreases astigmatism so you won’t need glasses to fix it after your surgical procedure, apart from curing the cataract.

The Surgical procedure
If you have a cataract, you’ll see an eye doctor. This doctor concentrates on eye surgical treatment as well as other eye issues. He’ll possibly tell you it’s ideal to wait to get rid of the cataract up until it begins to impact your day-to-day life. He can do the surgical treatment at a medical facility or an outpatient centre.
To get you prepared, your physician will:
– Measure your eye. This will certainly help him pick the appropriate implant for you.
– Provide you medicated eye drops to take for a few days in advance.
– Ask you to stop taking some medicines or to skip putting on contact lenses for several days ahead of the time of the surgery.
On the day of surgical procedure, he’ll:
– Numb your eye.
– Offer you a drug to help you relax. You may see light during the procedure; however you ought to feel absolutely nothing or only a mild pressure during the surgery.
– Make a tiny puncture in your cornea to get to the lens.
– Break your natural lens into pieces as well as remove it bit by bit.
– Put the implant in position.
– Allow the cut to recover on its own – no stitches.
You can usually go home in less than an hour, but you’ll need someone else to drive, as you won’t be permitted to drive that day.

Is It Risky?
Any type of surgical procedure has a chance of complications. It’s unusual after an intraocular lens implant, but you might see bleeding or get an infection. Redness or swellings are extra common.
More serious risks include: – A detached retina, which happens when the retina which is nothing but a layer of photo-receptor nerve cells separates from the rear of your eye. This is a clinical emergency situation.
– Vision loss.
– Dislocation – when the implant moves out of its natural position or implanted position.
You may also get an after-cataract anywhere from weeks to years after the surgical procedure. This occurs when the cells around your new lens get cloudy as well as your vision obscures. Your physician can fix this with a pain-free laser procedure.

Follow-Up Treatment
It will take about 8 to 12 weeks to fully recover. During that time:

– Keep your eye shielded with sunglasses as long as possible, and also sleep with your eye shield in the evening.
– Do not rub or press your eye, even if it’s scratchy or exudes a little bit of fluid.
– Take the medicated eye drops your doctor prescribes to help your eye heal up. You’ll use them for several weeks to assist your eye heal.
– Avoid most exercise or heavy lifting. The doctor will tell you when you can do those things again.

IOL Implants: Lens Substitute After Cataracts

An intraocular lens (or IOL) is a tiny, artificial lens for the eye which will replace the ageing natural lens. It replaces the eye’s natural lens that is eliminated throughout cataract surgical treatment.
The lens flexes (refracts) light rays that go into the eye, aiding you to see. Your lens should be clear. Yet if you have a cataract, your lens has become cloudy due to ageing. Objects look fuzzy, hazy or less colorful when you have a cataract. Cataract surgery removes this cloudy lens and also replaces it with a clear IOL to enhance your vision.
IOLs can be found in different focusing powers, just like prescription eyeglasses or contact lenses to see objects at various, different distances. Your eye doctor will certainly measure the length of your eye and also the curvature of your cornea for a suitable type of lens. These measurements are made use of to set your IOLs focusing power as well as choice of lens type.

What are IOLs made of?
Many IOLs are made from silicone, acrylic, or various other plastic compositions. They are also covered with a special material to help safeguard your eyes from the sunlight’s unsafe ultraviolet (UV) rays.

Mono-focal IOLs
The most typical type of lens made use of with cataract surgical treatment is called a mono-focal IOL. It has one focusing range. It is readied to focus for up close, medium range or distance vision. The majority of people have them set for clear distance vision. After that they wear spectacles for reading or close up jobs.
Some IOLs have various focusing powers within the same lens. These are called multifocal as well as accommodative lenses. These IOLs lower your reliance on glasses by providing you with clear vision for more than one distance range.

Multifocal IOLs
These IOLs give both distance and also near focus at the same time. The lens has actually different zones set at various powers.

Accommodative IOLs
These types of lens implants move or change shape inside your eye, permitting focusing at different distances by the same lens and come closest to your natural lens.

Toric IOLs
For people with astigmatism, there is an IOL called a toric lens implant, which not only remedies the cataract but also take care of your astigmatism issue. Astigmatism is a refractive error triggered by an uneven curvature in your cornea or lens. The toric lens is designed to remedy that refractive error.
As you prepare for your cataract surgical treatment, speak to your ophthalmologist about your vision needs as well as expectations. She or he will explain IOL options for you in even more detail.

Handling Irregular Corneas with Scleral Contact Lenses

Usage is an excellent alternative for effective visual rehab in these patients

Fully scleral contact lenses are a good option for achieving effective visual rehabilitation in irregular corneas and they have been extensively used though there is need to build up more awareness around them.
2 subgroups were earlier identified in types of scleral lenses depending upon the presence of corneal bearing or not: corneo-scleral or semi-scleral are their names. Just recently, the Scleral Lens Education Society (SLS) has defined a much more accurate differentiation between different types of scleral lenses not only based on the lens diameter, but also on the size of visible iris of the eye in which the lens is fitted, as has been outlined in Table 1 above.
SLS sustains public education that highlights the benefits and availability of scleral contact lenses to promote their usage.
Scientists found that fully scleral lens of a particular diameter can behave as mini-scleral or large-scleral, depending on the eye on which it is fitted.
This sort of lens has to always be fitted after being entirely filled with saline solution, staying clear of the formation of bubbles through the insertion that eventually can bring about discomfort and poor vision in the patient.
Scleral contact lenses have actually always been considered suitable for the correction of irregular astigmatism (post-corneal refractive surgical procedure, post-keratoplasty), including keratoconus as well as various other ectatic problems, as they have the ability to neutralise the effects of abnormalities with the tear film meniscus that develop with the cornea, while preserving high levels of comfort.
Nonetheless, there are also other symptoms viable for corneo-scleral as well as fully scleral contact lenses, such as the correction of refractive errors that cannot be dealt with satisfactorily with rigid gas-permeable (RGP) corneal or soft contact lenses, the introduction of prismatic corrections, for cosmetic functions as well as also in healthy corneas, due to the advantages of this type of lens: much less palpebral interaction, great convenience as conjunctitival sensitivity is lower than that of the cornea, no chances of producing corneal distortion if the fitting is adequate as well as a streamlined fitting procedure.
Additionally, the procedure of insertion and removal of the lens is simplified by the use a suction cup, avoiding the fingers coming in contact with the eye at all times.

The scleral Contact lens ICD
The ICD16.5 contact lens is a fully scleral contact lens that has four differentiated zones enabling a proper centration with no corneal touch and also a stable positioning over the conjunctiva.
These zones are: Central clearance zone (CCZ), Peripheral Central clearance zone (PCCZ), limbal clearance zone (LCZ), and also scleral landing zone (SLZ).
The geometry of these zones can be customized to accomplish a best fitting of the lens independently from the corneo-scleral profile.
Similarly, a peripheral toricity can be added if the conjunctival-scleral profile presents a significant level of astigmatism or to stabilise a scleral lens with toric power to make up for recurring astigmatisms through fitting.
This contact lens is fitted considering the sagittal elevation rather than keratometry that can be determined using optical coherence tomography (OCT), Scheimpflug video cameras, or more accurately with corneo-scleral topographers, such as the Eye Surface Profiler (ESP).
A central vault of around 300 µm is needed for providing a suitable fitting, without any corneal bearing while wearing because of a potential conjunctival compression of the lens (Figure 2).
This lens is an RGP contact lens manufactured in product HDS 100.
The product made use of is a thermoset fluorosilicone acrylate copolymer derived primarily from methylmethacrylate, trifluoroethyl methacrylate, and siloxane acrylate with a water content of less than 1% (Paflufocon D), with a Dk (oxygen permeability measure) of 100 Fatt (the unit of measure).

Results with scleral lens ICD16.5
The group carried out a study to assess outcomes achieved with the fully scleral contact lens ICD16.5 in corneas with different sorts of problems.
The research was consecutive and prospective.
The research consisted of a total of 42 eyes of 27 patients, 15 males (55.6%) and 12 females (44.4%).
The average age of patients in the study was 39 ± 12 years (range, 14 to 65 years).
Inclusion requirements for the research were that the participants had no active ocular disease, no severe dry eye, no previous intolerance to soft or corneal gas permeable contact lenses, and also they likewise accepted and signed informed consent papers.
A pre-fitting assessment is also confirmed to be a useful step in the procedure, and the study results bear this out.
In all cases, a very total pre-fitting assessment was carried out that included: filiation data, uncorrected and also corrected visual acuity, manifest refraction, eye aberration measurements, biomicroscopy, corneal topography, as well as previous anterior section evaluation by optical coherence tomography.
The patient was evaluated after 1, 3, 6 months and 1 year of contact lens wear to check the success of the fitting.
In our study, a total number of 25 eyes with keratoconus (59.5%) were fitted, four of them with previous implantation of intra-corneal ring segments and also 10 with previous corneal collagen cross-linking, 6 eyes with irregular cornea after previous LASIK surgery (14.3%), two eyes with irregular cornea after radial keratotomy surgical treatment (4.8%), three eyes after keratoplasty (7.1%), one eye with endothelial corneal decompensation (2.4%), two cases of dry eye (4.8%), as well as 2 eyes with nearsightedness magna (4.8%).
The mean sagital height required for the fitting was 4294.12 ± 292.56 Î 1/4 m (4,000 to 4,900 Î 1/4 m) and the mean optical power was – 6.96 ± 6.95 D (- 21 to +4 D).
After 1 hour of using the lenses, the mean apical vault determined by optical coherence tomography was 299.4 ± 85.56 Î 1/4 m (201 to 420 Î 1/4 m).
Concerning the visual outcomes, a considerable renovation in decimal visual acuity was achieved with the contact lens after 1 month of wearing compared to that acquired with eyeglasses prior to fitting (p < 0.001), without substantial modifications occurring during the remainder of the follow up (Figure 3).
This follows the results of previous researches making use of the very same version or various other versions of scleral contact lenses.

There was a propensity to an increasing positive over-refraction throughout the follow up, although it did not get to statistical significance (p = 0.17).
This adjustment followed a minor anterior (p = 0.91) and also posterior corneal flattening (p = 0.37), which did not get to either statistical significance.
Moreover, the noted change is in agreement with current research studies reporting the level of corneal molding induced by fully scleral contact lenses.
In our research, we found that a small yet statistically significant pachymetric increase was also observed at 3 months of wearing (minimum thickness p = 0.001, central thickness p = 0.08), without considerable changes later (minimal thickness p = 0.86, central thickness p = 0.88).
This minimal pachymetric increase has been reported by various other authors and does not seem to be related to issues of clinically relevant hypoxia as high Dk material has been utilized.
It was concluded in a prospective research study that, although a small percentage of corneal swelling was induced following 8 hrs of mini-scleral lens wear (generally <2%), modern high Dk (measure of permeability) mini-scleral contact lenses that vault the cornea do not generate clinically significant corneal edema (swelling) or hypoxic-related posterior corneal curvature changes during short-term wear.
Concerning ocular high-order aberrations, there was a considerable decrease, especially of the primary coma, as shown in Figure 4. This additionally has actually shown to be consistent with the considerable gain in fixed range visual acuity that has been attained with the contact lens.
The tolerance of the contact lens was good in all cases, with the following issues or difficulties reported:.
– Abandonment of fitting: 3 cases (6.8%) due to bad tolerance as a consequence of an excessive lens indentation throughout the day.
– Lens power changes needed throughout the first month (8 cases, 18.2%).
– Changes of the scleral landing zone due to lens fogging (5 cases, 11.4%) or too much scleral indentation (2 cases, 4.5%).
– Episodes of occasional conjunctival hyperemia (tobradex, thealoz, recugel) (5 instances, 11.4%).
In conclusion, the fully scleral contact lens ICD16.5 is a good choice for attaining an effective visual rehab in irregular corneas, specifically if previous fittings with other kinds of contact lenses have fallen short.
This kind of lens has the ability to provide a significant increase in visual acuity combined with a considerable improvement in visual acuity, maintaining high levels of comfortability.
The fitting process of these lenses is fairly easy and can be highly optimized by introducing the proper changes in the different zones of the lens.

What Are Bifocal Contact Lenses For Astigmatism?

In the past, if you put on toric soft contacts for astigmatism, you had to make a decision sometime after age 40, when you also began to have difficulty reading due to the onset of presbyopia: Either start putting on reading glasses over your contacts or change over to bifocal rigid gas permeable contact lenses, which may not be comfortable for everyone.
For many people, neither of these were desirable options.

First of all, having to wear and carry around reading glasses defeats the purpose of wearing contact lenses, the purpose of which is to be free from eyeglasses for various reasons like looks and convenience. And though reading glasses can restore your near vision after age-related presbyopia becomes apparent, readers blur your distance vision which need a different correction – so you have to keep putting them on (for reading purposes) and then taking them off (to see at a distance, say across the room or at the TV). It’s annoying and inconvenient.

Bifocal contact lenses for astigmatism allow people over age 40 who have irregular corneas along with the onset of presbyopia to see clearly at all distances without wearing reading glasses and thus eliminate the need to wear reading glasses over contacts.
For some people with astigmatism, switching to bifocal gas permeable (GP) contacts after age 40 can restore clear vision at all distances, but these are rigid, not soft lenses. So, getting used to wearing rigid GP lenses after comfortably wearing soft lenses can be a challenge, and some people may simply not be able to adapt to GP lenses.
Also, to remain comfortable, GP lenses must be worn every day, unlike soft contact lenses. This puts an end to the convenience of a flexible wearing schedule that soft contacts offer for people who don’t want to wear contact lenses all day, every day.
And while it’s true that soft bifocal contact lenses have been available for many years, these lenses didn’t correct astigmatism in the past. But now that has changed.
New soft bifocal contacts that also correct astigmatism – called toric multifocal lenses which are also soft contact lenses – offer people with both astigmatism and presbyopia the clear vision they need at all distances they desire, with the wearing comfort they’ve come to expect with single vision (non-presbyopic) toric soft lenses, meant to correct just one refractive error.

Features of soft bifocal contacts for astigmatism
Several bifocal and multifocal soft contact lenses for astigmatism are available in the United States and have been for some time. During your contact lens exam and fitting, your eye care practitioner will be able to determine whether you are a good candidate for them, and which brand is the best choice for your particular needs.
To keep the astigmatism correction properly positioned in front of the eye, most of these lenses are designed with a stabilization system, so that they don’t move and change the correction.
Some are fully customized to each wearer’s prescription needs, and are fitted to prescription while others come in a more limited range of distance and near powers, as well as astigmatism correction.
Generally, there are two types of designs for soft bifocal contacts for astigmatism. One type features a progressive power design, similar to the design of progressive eyeglass lenses with melting zones for each distance. The other features concentric rings of different powers for different viewing distances and one may choose depending on convenience.
In some concentric ring designs, the portion of the lens covering the center of the pupil has the power for near vision (“center-near” designs). In others, the central zone of the lens contains the power for distance vision (“center-distance” designs).
Materials used for soft bifocal contacts for astigmatism include conventional hydrogels and more highly breathable silicone hydrogels. Monthly, bimonthly, quarterly and semi-annual lens replacement schedules are possible, depending on the lens brand, design and material and one may make a choice depending on comfort and convenience.

Hybrid bifocal contacts for astigmatism
Another option worth considering if you have both astigmatism and presbyopia is multifocal hybrid contact lenses. Hybrid contacts have a central optical zone made of rigid gas permeable plastic, which is surrounded by a peripheral (non-optical) zone made of a soft lens material for easier adaptation, for those that do not prefer a completely soft lens. For some people, this offers greater wearing comfort than conventional GP lenses, which are rigid throughout.

Cost of bifocal contacts for astigmatism
Because of the complexity of the design and therefore the manufacturing of astigmatism-correcting bifocal contacts and the time and expertise required to fit them, expect to pay significantly more for these contact lenses, than your usual contact lenses.
It’s not unusual for bifocal contacts for astigmatism to cost at least twice what you would pay for toric lenses that correct just astigmatism (with or without nearsightedness or farsightedness) and up to twice what you might pay for custom bifocal contacts that do not correct astigmatism, which is the price one may have to pay for comfort and convenience.

You still may need glasses (occasionally)
Bifocal contacts for astigmatism usually provide excellent functional vision for most daily activities. But for some tasks, you will likely see better and/or be more comfortable with readers over your contacts or with prescription eyeglasses rather than contact lenses, so do not expect to get rid of glasses completely.
For example, it’s a good idea to have a pair of reading glasses handy to wear over toric multifocal contacts for reading very small print (such as that on medicine bottle labels) or for fine detail work, like threading a needle and hand sewing, which is not that much of an inconvenience at all.
Also, for prolonged computer work and extensive reading, you typically will have greater clarity and comfort wearing eyeglasses rather than contact lenses of any kind, because of the problem of dryness as explained here: this is because we tend to blink less frequently during these tasks like computer work, which causes contact lenses to become dry, where moisture is essential.
The quality of vision of specialty contact lenses such as bifocal contacts for astigmatism can be especially affected if the lenses dry out and don’t move adequately or remain properly positioned on the eye for accurate astigmatism correction. Also, people over age 40 are more prone to dry eyes than younger adults.
For prolonged computer work, we may recommend computer glasses rather than general-purpose bifocals or progressive lenses. Eye doctors can prescribe computer glasses that are specifically tailored to provide the sharpest vision and greatest comfort for your preferred working distance in front of your computer screen.
