Prevention includes wearing hats and sunglasses when outdoors on windy or sunny days. But, if treatment is necessary, drops relieve dryness, redness, irritation and inflammation. Often, surgery is not necessary. Pterygia often recur after removal. A combination of drops and preventative measures are critical post-operatively to prevent recurrence.
Corneal transplants are almost never an option with recurrent pterygia.
But a conjunctiva transplant may be at the time of excision. Despite adequate excision and proper post-operative care, dryness and irritation may persist.
