Cataracts and Glaucoma: A Patient’s Double Agony

Patients with both cataracts and also glaucoma necessitate special attention. Cataracts might normally exist together with glaucoma, have an causative effect on glaucoma, and/or might also be an outcome of glaucoma surgical treatment.
A cataract is a clouding of the lens inside the eye which leads to a decrease in vision, normally caused as natural ageing process of the body and the eyes, which are a part of it. When a patient has glaucoma that requires an operation, there might be a distinct chance to get rid of the existing cataract side-by-side without substantially increasing the risk of the glaucoma surgical treatment. In addition, when an individual has cataracts affecting their vision together with glaucoma, getting rid of the cataract may provide an opportunity to do a glaucoma surgical procedure at the same time that might lower the individual’s need for glaucoma eye drops or improve eye pressure control.
Cataract surgical treatment may be integrated with one of numerous glaucoma surgeries including canaloplasty, glaucoma drainage devices, trabeculectomy, endocyclo-photocoagulation, and also the more recent micro-invasive glaucoma surgeries (MIGS). The MIGS procedures are especially suited for integrating with cataract surgical procedure since they can usually be carried out by utilizing the exact same incision through which the cataract is removed, reducing even further, a lot of the invasion or intrusion of the eye. However, they are not suitable in every case as they count on the eye’s natural drainage system and may not get the eye pressure to a low enough level for some patients. The iStent is a type of MIGS procedure that is currently FDA approved for use in combination with cataract surgical treatment.
In some particular circumstances, cataract surgery alone may also be considered. As an example, in some patients with narrow angles, the cataract becomes too big as well as crowds the other structures in the eye (especially the water drainage angle). When this happens, doing a cataract surgical procedure with a lens replacement may open up the drainage angle and also improve the eye pressure.
The decision of whether or not combined  cataract-glaucoma surgery ought to be performed, and the choice of glaucoma surgery, relies on different aspects including the type of glaucoma and also its severity. Your doctor will certainly take all these essential factors into consideration when advising what is best for your eye.
Cataract surgical procedure in a patient with glaucoma may give rise to unique concerns. As an example, in patients with exfoliation glaucoma there is a higher risk of complications because of inherent weakness in the supportive structure of the natural lens (the zonules). Some recent intraocular lenses may not be appropriate for patients with advanced glaucoma because they affect contrast sensitivity (the ability to distinguish between an object and its background) or might cause additional sensitivity to glare. Eye pressure spikes after cataract surgery might be a lot more common in patients with underlying glaucoma as well as importantly, glaucoma patients are most likely to be susceptible to damage from a temporary increase in eye pressure.
In conclusion, in people with coexisting cataract as well as glaucoma, surgical treatment presents exceptional challenges. There are numerous treatment options as well as several variable factors into the decision to choose a certain treatment. A thorough discussion with your physician is important in order to figure out the best choice for you.
