What to Expect from a Pterygium Surgery Consultation

A pterygium is a fleshy, wedge-shaped growth on the white of the eye that extends from the conjunctiva onto the clear corneal surface. Often developing on the nasal side of the eye (closest to the nose), it is strongly associated with ultraviolet light exposure and is more common in people who have spent significant time outdoors—particularly in sunny or windy climates. While many pterygia remain small and cause only cosmetic concern or mild irritation, others grow progressively, eventually threatening vision and requiring surgical removal.

When to Consider Surgery

Not every pterygium needs removal. If yours is small, stable, and not causing bothersome symptoms, regular monitoring with your optometrist or ophthalmologist may be all that is required. Preservative-free lubricant drops can manage mild irritation and dryness associated with the irregular surface. However, surgery becomes advisable when the pterygium is causing persistent redness, irritation, or discomfort despite conservative treatment; when it is growing toward the visual axis and threatens to obstruct your pupil; when it is inducing significant astigmatism by mechanically distorting the corneal shape; or when its cosmetic appearance is a source of self-consciousness.

Some patients present with bilateral pterygia—growths on both eyes—which can progress at different rates and may eventually require surgery on each eye, typically staged several weeks apart.

Your Consultation with Ms Menassa

During your consultation, Ms Menassa will examine the pterygium under magnification using a slit lamp biomicroscope to assess its size, thickness, vascularity, and proximity to the pupil. Corneal topography may be performed to map any astigmatism the growth is causing and quantify its effect on your vision. She will review your history of UV exposure, outdoor activities, and any previous pterygium treatment, and will examine the fellow eye for early changes that might benefit from preventive measures.

Ms Menassa will explain her assessment in plain language, discuss whether surgery is recommended at this stage or whether monitoring is more appropriate, and answer your questions. If surgery is recommended, she will describe the surgical technique in detail, the expected recovery timeline, and—importantly—the specific strategies she uses to minimise the risk of recurrence, which is the principal concern in pterygium surgery.

The Surgical Approach: Conjunctival Autograft

Ms Menassa performs pterygium removal with conjunctival autograft—currently recognised as the gold standard surgical technique. The procedure involves careful excision of the pterygium tissue from the cornea and surrounding conjunctiva, followed by coverage of the exposed area with a thin graft of healthy conjunctiva harvested from beneath the upper eyelid (a donor site that heals completely without functional consequence). The graft is secured using fibrin tissue glue rather than sutures, which significantly improves post-operative comfort and reduces the foreign body sensation during healing.

The autograft technique dramatically reduces recurrence rates compared to the older bare sclera excision method, which simply removes the pterygium and leaves the exposed area to heal by secondary intention. Published meta-analyses show recurrence rates of approximately 5-10% with conjunctival autograft compared to 30-80% with bare sclera techniques. This is why the additional surgical time required for autograft harvesting is considered well worthwhile.

What About Anti-Metabolites?

Some surgeons use anti-metabolite agents such as mitomycin C during pterygium surgery to further reduce recurrence risk. While effective, these agents carry risks including delayed wound healing and, rarely, scleral thinning. Ms Menassa will discuss whether adjunctive treatment is appropriate for your specific case—for example, in recurrent pterygia or particularly aggressive growths where the recurrence risk is higher.

Recovery

The eye will be red, sore, and watery for one to two weeks after surgery—this is the normal healing response and should not alarm you. Antibiotic and anti-inflammatory drops are used for several weeks to prevent infection and control inflammation. Most patients are comfortable enough to return to work within a week, though the eye may remain visibly red. The redness gradually resolves over four to eight weeks as the graft integrates and the conjunctival blood vessels settle.

The final cosmetic result—a white, quiet, natural-looking eye—is typically excellent, and most patients are very pleased with both the appearance and comfort of their eye after complete healing. UV protection with quality sunglasses is recommended lifelong to reduce the risk of recurrence and protect the fellow eye.
