The surgical treatment options for pterygium, an abnormal growth on the eye's frontal surface can be treated with several surgical techniques. The rates of pterygium coming back varies depending on the surgical technique employed and other factors related to the patient and surgery. The objective of this study is to assess the efficacy and safety of incorporating a single amniotic membrane with stem cells in the treatment of primary pterygium, aiming to enhance surgical outcomes and minimize recurrence rates.

The surgical treatment options for pterygium, an abnormal growth on the eye's surface, encompass various approaches. These include standard surgical excision, which involves removing the pterygium using traditional surgical methods and more recently Simple Limbal Epithelial Transplantation. Recurrence rate of pterygium varies depending on the surgical technique employed and other factors related to the patient and surgery.The objective of this study is to assess the efficacy and safety of incorporating a single amniotic membrane with stem cells in the treatment of primary pterygium, aiming to enhance surgical outcomes and minimize recurrence rates.
