Pterygium. When a wedge of tissue grows onto the cornea.
Pterygium - sometimes called surfer's eye - is a benign growth caused by chronic UV exposure. When it affects vision or comfort, modern surgical removal with autograft has dramatically reduced recurrence.

A fleshy wedge of tissue grows from the conjunctiva onto the cornea.
Pterygium grows slowly over years, typically on the side of the eye closest to the nose. Small pterygia may stay quiet for decades - but as they grow toward the central cornea, they can induce astigmatism, blur vision, and cause chronic irritation.
Modern pterygium surgery uses a conjunctival autograft technique: after removing the pterygium, we transplant a small piece of healthy tissue from beneath the eyelid to cover the area. Recurrence rates are dramatically lower than older bare-sclera techniques.

Common questions.
Do all pterygia need surgery?
No. Small, asymptomatic pterygia can often be monitored. We typically recommend surgery when the pterygium is causing visual symptoms, growing toward the central cornea, or producing chronic irritation.Will my pterygium come back after surgery?
Recurrence is the main risk. Modern autograft technique has dramatically lowered the rate compared to older approaches, but UV protection after surgery is essential.Is pterygium surgery covered by insurance?
Yes, when the pterygium is causing visual or symptomatic problems. We verify benefits and explain any out-of-pocket costs in writing before surgery.
