AIM: To compare the efficacy and complications of conjunctival limbal autograft (CLAU) and amniotic membrane transplantation (AMT) vsintraoperative mitomycin C (MMC) and AMT for treatment of recurrent pterygium. METHODS:Forty eyes of 40 patients with recurrent pterygium underwentCLAU and AMT (20 eyes) or intraoperative MMC (0.02%, 3 min) and AMT (20 eyes). Three eyes (15%) had symblepharon before surgery in each group. Recurrence was compared in each group by using chi(2) test. RESULTS: No major postoperative complications occurred during 6-19 months of follow-up. In CLAU/AMT group, no pterygium recurrence was observed. Recurrence occurred in four eyes (20%) in MMC/AMT group after 3 and 4 months (P-value=0.035, chi(2) test). No recurrence of pterygium or symblepharon was seen in six eyes with recurrent pterygium and symblepharon (three eyes in each group). CONCLUSION:CLAU with AMT seems to be more effective than intraoperative MMC with AMT for treatment of recurrent pterygium.
