Objective To explore the therapeutic effect of limbal stem cell transplantation and human amniotic membrane transplantation in the treatment of pterygium.Methods Sixty-nine cases (87 eyes) with pterygium were divided into two groups.Group A:Thirty-four cases (42 eyes) were treated with limbal stem cell transplantation;Group B:Thirty-five cases (45 eyes) were treated with human amniotic membrane transplantation.Results All cases were followed up for 2 years.Forty eyes were cured (95.24%) and 2 eyes with recurrence (4.76%) in group A.Forty-one eyes were cured (91.11%) and 4 eyes with recurrence (9.89%) in group B.Conclusion Limbal stem cell transplantation and human amniotic membrane transplantation are effective in the treatment of pterygium.Recurrence rate is low.There is no significant difference between two methods in statistics.
