The first procedure consists of corneal autograft sampled at noon or six o'clock on the pterygium's excision bed, combined to a conjunctival flaps translation. The second technique consists of a monoblock corneoconjunctival graft with a limbic hinge. The operative difficulties, post-surgical complications and results are discussed. The results seem very promising: one recurring case out of 34 grafts performed. The recurring risk, more acute in tropical environment where it is frequently impossible to obtain corneal homografts is greatly reduced by autografts.
