Recurrence Rate of Mini-SLET vs. Limbal-Conjunctival Autograft in Primary Pterygium Excision

Recurrence Rate of Mini-SLET (Simple Limbal Epithelial Transplantation) vs. Limbal-Conjunctival Autograft in Primary Pterygium Excision

To study the efficacy and safety of amniotic membrane transplantation as an adjunctive therapy after surgical excision of primary pterygium and compare the clinical outcomes with conjunctival autograft

Prospective Randomized Blind Clinical Trial

Sixty-four eyes of 64 patients with primary nasal pterygium have been operated by two surgeons (E. G-H, A. N-C). All patients are randomized to undergo Mini-SLET or limbal-conjunctival autograft transplantation as an adjuvant therapy after pterygium excision.

Four eyes were treated with Mini-SLET(group 1), and 26 eyes have been operated with conjunctival autograft (group 2). Patients will be followed up at 1 day, 1 week, 1, 3, 6, 9 and 12 months postoperation. The main outcome measurement was a recurrence rate after surgery.

Inclusion Criteria:

• Patients with primary nasal pterygium > 2mm

Exclusion Criteria:

• Pregnant
• Previous ocular surgery
