The traditional group was treated with pterygium excision in combination with autologous conjunctival transplantation; the modified group was treated with modified amniotic membrane transplantation; to observe the curative effect of the two groups.Results: After all of patients were followed up for 1 year, 122 cases were cured and 16 cases were recurrence, and the recovery rate was 88.41% in traditional group; 131 cases were cured and only 7 cases were recurrence, and the recovery rate was 94.93% in modified group and was better than traditional group; the difference between the two groups was statistical significant (x2=5.02,P<0.05).Conclusion: The modified amniotic membrane transplantation method is simple in operation, mini invasive for eye tissue, and can retain conjunctival tissue in utmost; it also can improve success rate of surgery and be an effective mean for treatment of pterygium.
