Investigating the Recurrence Rate of Pterygium after Surgery Using Mitomycin C for 1 Minute and Free Conjunctival Graft

Background and Aim: Pterygium is a progressive fibrovascular lesion associated with a high recurrence rate following simple excision (24% to 89%). This study aimed to evaluate the effectiveness of using 0.02% Mitomycin C for one minute combined with conjunctival autografting in reducing pterygium recurrence and assessing visual outcomes. Materials and Methods: This study included 60 patients with pterygium between 2017 and 2018. Surgical intervention involved pterygium excision followed by topical application of 0.02% Mitomycin C for one minute and conjunctival autografting. Patients were examined on post-operative days 1, 7, and 30, and were subsequently followed for 120 days. This study also evaluated recurrence rate, visual acuity, spherical equivalent, and astigmatism.
