Methods: The study included 150 eyes of 150 patients of primary pterygium. Twenty four to 74 years of age (mean 49 ± 12 years). Simple excision under local anesthesia was performed then closure of the bare sclera by sutureless and glue free conjunctival autograft in 50 eyes of 50 patients (group 1), versus sutured free conjunctival autograft in 100 eyes of 100 patients (group 2).
