Introduction: Pterygium is a common degenerative conjunctival disease, for which several surgical techniques were adopted, but none proved to be ideal because of the relatively high recurrence rate after removal. Objective: the primary outcome measure was to assess the recurrence rate of pterygia after surgical removal with conjunctival-limbal transplantation; secondary outcome measure was to assess safety of the procedure. Method: study design: a prospective interventional study Selection of 20 cases of advanced fleshy pterygia with at least 3.5 mm horizontal extension on the cornea, some primary and some with multiple recurrences, surgical removal with conjunctival-limbal autografting was done Then postoperative fellow up for 3-6 years checking: 1-evidence of recurrence. 2-evidence of limbal stem cell deficiency. Results: mean age was 53.45+- 15.78 year After surgery, the minimum fellow up period was 3 years for primary pterygia, and 6 years for recurrent pterygia NO recurrence was observed during that period; in addition no signs of limbal stem cell deficiency were seen. Conclusion: Surgical removal with conjunctival-limbal transplantation proved to be safe and effective for both primary and recurrent pterygia, with NO recurrence rate.
