The bare sclera technique, while historically used, has a high recurrence rate. Simple excision with topical corticosteroids alone is also associated with significant recurrence. Conjunctival autograft (transferring a piece of healthy conjunctiva from the same eye to cover the bare scleral bed) or amniotic membrane transplantation are currently considered the most effective surgical techniques to reduce pterygium recurrence rates significantly. These methods provide a barrier to prevent conjunctival regrowth and fibroblast proliferation. Laser photocoagulation is not a standard treatment for pterygium.
