Evaluation of the Modified Mini-SLET Technique in the Surgical Treatment of Primary Pterygium

Objective: To evaluate the efficacy of the modified mini-SLET (simple limbal epithelial transplantation) technique in the surgical treatment of primary pterygium. Methods: This was a case series involving 31 eyes of consecutive patients with primary pterygium who were treated with the modified mini-SLET technique. After pterygium excision, a 2x4-mm fragment of healthy conjunctiva was removed from the superior temporal region and was later cut into several small pieces and fixed onto the receiving site with fibrin glue. All patients were evaluated on the 1st, 7th, 30th, 90th, 120th and 180th days postoperatively. Results: The population's mean age was 50.3 ± 13.4 years (range 26 to 77 years). There were 17 males (54.8%) and 14 females (45.2%). The proportions of eyes with grade 1, grade 2 and grade 3 pterygium were 12.9%, 48.4% and 38.7%, respectively. During the 6-month follow-up, 2 eyes showed granuloma development, which was resolved with the use of topical corticosteroids. There was recurrence of the lesion in 2 eyes (6.5%). There were no serious complications. Conclusion: This surgical option offers a safe and effective alternative, especially in cases where there is little conjunctive tissue available.
