The recurrent pterygium and repeated surgical operations destroy the normal Bowman's membrane which acts as a barrier to the ingrowth of conjunctival tissues. The insertion of a lamellar corneoscleral graft in the area of involvement seems to be a logical approach. Measurements are made on both the recipient and donor eye using the limbus as a point of reference. The dissections are made by hand. The 10-0 monofilament suture can be left indefinitely with little discomfort. The interrupted sutures are absorbed after the sclera has become adequately fixed by fibrous tissue.
