Three general methods are used in pterygium surgery. 1. Removing the pterygium and replacing the place with the person's own conjunctival tissue (autograft): In this method, after removing the pterygium, the conjunctival tissue that is usually removed from under the upper eyelid is used for the place where the pterygium is removed, and the new tissue is transplanted there. The risk of pterygium returning in this method is low and it has the best result in terms of appearance. 2. Removing the pterygium and replacing the site through the grafting of the amniotic layer of the fetus: this method is the same as the previous method. With the difference that the tissue is not removed from the person's own eye and the amniotic layer of the donated placenta of a newborn baby is used. 3. Removing the pterygium and not transplanting another layer at the place of removal, which is similar to the previous methods. However, tissue is not placed at the place where the pterygium is removed. Usually this method is used less often. The risk of return of pterygium is higher in this method.
