Here Today, Gone Tomorrow: Visual Outcomes Of Pterygium Surgery

Pterygia as well as pinguecula are appealing as well as some of the oldest pathologies that ophthalmologists take on. Presentations vary in various tissue distributions as well as vascular patterns from small atrophic lesions to huge hostile vision-compromising fibro-vascular growths advanced cases.

What began a decade earlier with celebrities, news anchors, as well as models seeking our services for cosmetic results of their pterygium surgery has ended up being a common demand of males and females from all walks of life. I see a reasonable number of professional golf players, surfers, and devoted outdoor enthusiasts.

Although extended periods of sunlight exposure is thought to develop pterygia and also pinguecula formation, our 20-year experience with patients from the U.S. as well as around the world points towards a hereditary probability that was verified by our observation of bitemporal developments (in both eyes) in youngsters in equatorial countries where we carry out pro bono work.

While visual symptoms can seem unimportant to ophthalmologists, patient problems are real as well as range from self-consciousness, reduced self-worth, and embarrassment to clinical depression as a result of their eye appearance. This understanding sustained our wish to constantly elevate bar on ocular surface surgical procedures to a cosmetic end result.

As in LASIK and also cataract surgical treatments in which we aim for spectacle-free vision with a flawless looking eye, We advise our colleagues and fellow surgeons that at every action in ocular surface surgical treatment they ought to continuously think about exactly how they desire this patient to look right away postoperatively and years later. Eliminating the lesion is one objective and also improving the look of the eye (with marginal visual effect) is the other goal, however both are essential.

Taking into consideration the consistent end results of our pterygia surgical procedure, patients have actually been actively looking for pinguecula correction.

The Gulani Classification
Over twenty years, we have classified pterygia into classifications (based upon head/neck adhesion, vascular pattern, and also draw test) and continuously research the presentations as well as results to improve my strategy and also results. This additionally highlights the truth that pterygial looks as well as size do not predict the surgical ease or end result.

Gulani Iceberg 3-step method
We have sharpened the “Iceberg Strategy” over 2 decades based on more than 700 surgical procedures, with normal outcomes. The surgical treatment gained that name because the noticeable component of the pterygium is simply the tip of the iceberg, as well as the actual development often tends to be much deeper. The surgery makes it possible for patients with visual pterygia and pinguecula and those with persistent and also aggressive vision-threatening pterygia to hope for clear, white eyes starting day 1 postoperatively.

We began originally with a sutured method, as well as advanced it to include amniotic grafting with due credit to another doctor’s work which we inculcated 14 years back. We then aspired to make it suture-less using the Tisseel Glue and ultimately to today’s visual end results with refractively neutral endpoints.

Though we have utilized all types of amniotic grafts in the vast range of Cryo-preserved and dehydrated choices, as well as various other newer ones on the market including those in development globally, our amniotic graft of choice remains to be the Amniograft.

The Iceberg Method neither endangers nor detrimentally affects vision because no corneal cuts are made. While the typical pterygia reappearance rate hovers near 39%, that with the Iceberg strategy has been less than 0.5%.

In a normal case, anesthesia is administered with topical tetracaine hydrochloride used preoperatively with topical moxifloxacin. Intra-lesion-anesthesia (1-2 cc of lidocaine with epinephrine) is used. Lately, patients have been requesting laryngeal mask airway anaesthetic. Given that a lot of these patients are young and healthy and also in some cases require considerable surgical treatment, this anesthesia helps with a comfortable experience and safe recuperation.

Depending on the look as well as draw test, we come close to the pterygium at the contracted medial conjunctival layer and also proceed medially to limbally or from the head toward the medial conjunctival layer.

The head of the pterygium is first marked under the cornea with a posterior-to-anterior sweep using the Gulani Pterygium Cross-Action Spreader. In instances with mild bonds, the pterygium can be divided quickly from the cornea (mostly peripheral pterygia and also those in elderly people) or peeled in one centrifugal motion.

After corneal smoothing with a specifically designed blunt blade, remnant tissue (especially with abrasive pterygia) is meticulously removed with a toothed forceps medially to limbally. The blade is utilized to smooth the limbus. A wek-cel sponge taken in 1:1000 epinephrine is put into the nasal hole where the cut pterygium is pushed right into hemo-stasis. When this step is finished, the area is without blood for dissection. Another benefit is that an area has actually been created in which to put the amniotic graft.

Pterygia dissection is the most important action. The entire pterygia plane is marked sub-conjunctivally as if dividing a fan-shaped scar with tentacles right into the fornices and also medial angle. The pterygium is pulled superiorly and also vertically to stay clear of damaging the underlying medial rectus. By cutting vertically rather than flat, unneeded involvement of orbital fat, bleeding, as well as iatrogenic damage to the medial rectus is avoided.

Upon removal, the pterygium looks like a spreading mass of tentacles. It is essential to eliminate the whole mass to avoid reoccurrence.

The pterygium is dissected superiorly to prevent buttonholing the conjunctiva and also invading the orbital septum and inferiorly to avoid cutting the underlying muscles, which is rechecked after the pterygium is removed and These are essential steps to ensure a clean and complication free surgical removal.

There is no to very little intraoperative blood loss. Cautery is done moderately and just for cosmetic reasons.

Cosmetic surgeons ought to patiently choose at the episcleral remnants to remove the underlying sclera to eliminate all pterygia cells from the area of impact.

Parts of wek-cel sponges are soaked in mitomycin C (MMC) 0.04% as well as positioned under the conjunctiva in the area of the dissection for 30 seconds. MMC application on the sclera must be prevented and the sclera dried with a tidy wek-cel sponge. After getting rid of all sponges, the area is flushed copiously with well-balanced salt solution.

The cornea functions as an illuminated receiving table on which to drape the amniotic membrane, which is put on the raw area as well as treated with a Tyre-Tool technique for a smooth and tools-free finish. This eliminates touching the membrane with any kind of tool, to make sure that it slides under the surrounding cut conjunctival side medially, superiorly, and also inferiorly.

The amniotic graft is milked to comply with the global contour making use of a specifically developed forceps that squeegees the graft on the sclera. Tisseel Glue is applied under the membrane layer as two separate parts, and also the membrane is squeegeed once again in 2 quick moves to a pearly white and also smooth look. The conjunctiva and underlying tenons are glued; they are closed in a C-shape with median facing convexity to make certain closure of any type of possible space in between.

The fornices are checked for too much glue, which can create irritability as well as keratitis on the first postoperative day, and also gotten rid of with a forceps sweep. The very same blade is used in one sweep to cut the excess graft at the limbus. The excess graft is peeled off as it clears the cornea as well as also confirms bonding of the remaining graft. This makes certain that there is no bumpy anatomy at the limbus as well as patients can resume contact lens wear very early postoperatively or undertake laser vision surgical procedure in the near future.

In comprehensive cases with medial corneal epithelial flaws (arising from peeling off of an aggressive pterygium head), we suggest Prokera or Ambiodisc additionally in the postoperative period.

All patients are instructed to look at their eye in a mirror on day 1 postoperatively. We observe their exclamations/reactions, which while always pleasing, vary greatly based upon their cultures and also individualities. The majority of patients are satisfied with their visual outcomes within 24-hours and also go back to day-to-day tasks within a couple of days.

Turning non-candidates into candidates
The significance of this strategy exceeds successfully treating pterygium and also pinguecula and attaining sparkling white eyes 1 day postoperatively. Actually, it is a technique that transforms non-candidates that had actually formerly undertaken a LASIK or premium IOL cataract surgery with tissue-induced irregular astigmatism, corneal marks, tear film instability, or higher-order aberrations into candidates by removing corneal scars as well as pterygia cells with a resultant clear as well as quantifiable optical system.
Since lots of individuals have already undertaken a LASIK or premium cataract surgery, this method keeps their enhanced vision due to the fact that LASIK flaps are not misshaped, keratitis is not induced, and corneal desiccation/distortion does not take place compared with traumatic methods or refractively damaging corneal incisions.

We have actually done laser vision surgical treatment and implanted multifocal/toric/ implantable collamer lenses as well as even Intacs in patients that have undertaken our amniotic graft pterygium and also pinguecula elimination surgical procedures with effective results.

Given the no-cut nature of my grafting treatment, no induced refractive modifications occur. Good vision is preserved or even improved by relieving the astigmatism caused by pterygia-induced pull on the cornea.

Considerations
Regardless of the consistent results and high patient satisfaction, I position excellent focus on preoperative patient education. Patients are advised that this is a major surgical procedure with attendant risks. Even with a very low reappearance rate, scarring as well as worse-looking eyes are possible.

Patient recovery patterns play an essential role in final outcomes. We recommend caution to specialists that advertise this treatment under eye-catching names as we have had countless patients consulting us with complications of these treatments for correction.

3 of my cases with unfortunate scenarios are worthy of mention.

One patient who was pleased with the sparkling white eye postoperatively went to the local eye specialist that did not see stitches or inflamed red areas postoperatively and also attempted checking for the graft with a Q-tip across the eye, which got rid of the glued graft from the eye. The patient returned to me for re-grafting.

The 2nd case was a patient that needed muscle alignment surgical procedure, and also the 3rd patient was followed for a local pupillary shape anamoly that is improving.

All 3 patients had actually undergone extensive bitemporal surgery. Although a lot of our patients with comparable medical profiles have actually done extremely well, we recommend that patients have one lesion removed each time.

In summary, pterygium as well as pinguecula surgical treatment can be approached cosmetically, also in extensive situations, as well as not only enhanced pathologically as well as functionally, however additionally raised to an aesthetic end result. Furthermore, numerous cases can after that gain from vision correction surgical procedure for associated ametropia for the concept of “look great and also see great!”.
