This prospective study was undertaken to evaluate limbal conjunctival autotransplantation in the management of cases with recurrent pterygium. At present, new surgical techniques to prevent pterygium recurrence following surgery are in investigation. In recent years, it has been postulated that pterygium is due to hypofunction of limbal stem cells. Thirty-one out of 49 patients with recurrent pterygium were treated by limbal-conjunctival autograft transplantation and the other 18 treated by Czermak technique, including two line of limbal cauterization intraoperatively, and used as a control group. During a mean follow-up period of 10 months (ranging 3-18 months), 4 recurrences (13.3%) in the limbal-conjunctival autograft transplantation group and 9 recurrences (50%) in the control group were observed. We conclude that this was a successful method to prevent secondary recurrence in the management of recurrent pterygium patients under 40 years of age.
