Recurrence and Complications after 1000 Surgeries Using Pterygium Extended Removal Followed by Extended Conjunctival Transplant

Abstract

To document the recurrence rate and complication rate of pterygium extended removal followed by extended conjunctival transplant. An open, prospective study of consecutive pterygium patients undergoing pterygium extended removal followed by extended conjunctival transplant. The study included 1000 consecutive patients undergoing pterygium surgery between August 2001 and September 2009. All patients underwent pterygium extended removal followed by extended conjunctival transplant by the author with attempted follow-up for 1 year. Recurrence and complication rates. Follow-up of >1 year was obtained in 99% of patients. There was 1 recurrence in the 1000 surgeries (0.1%) with 95% confidence intervals of 0.003%-0.56% (Fischer exact test). Seven patients required further surgery: 3 had graft replacements, and 1 each for recurrence, strabismus, inclusion cyst, and granuloma. One patient lost 4 lines of vision from a corneal ulcer. Pterygium extended removal followed by extended conjunctival transplant results in one of the lowest recurrence rates reported in the world's literature and an acceptable complication rate.
