To compare and evaluate the safety and efficacy of two surgical techniques for the management of primary pterygium.Prospective randomized clinical trial using the   Consolidated Standards of Reporting TrialsStatement for parallel group randomized trials.Department of Ophthalmology, govt.siddartha medical college,vijayawada.A.P The study included 100 eyes of 100 patients with primary pterygium. The mean age was 40 ± 12 years (range 27–64 years). Simple excision under local anesthesia was performed followed by closure of the bare sclera by suture less and glue free conjunctival autograft in 50 eyes of 50 patients (group 1), versus the conventional method of a sutured conjunctival autograft in 50 eyes of 50 patients (group 2).

The pterygium recurrence rate was 4% for group 1, 6% for group 2.Graft dehiscence occurred in 2 eyes out of 50 (4%) in group 1. Graft retraction occurred in 2 (4%) out of 50 eyes for group 1 versus 3eyes (6%) in group 2. Pyogenic granuloma occurred in2 eyes (4%) out of 50 in group 2. No other serious complications were noted. At the 6 week visit the overall patient satisfaction was significantly higher for group 1 , compared to group 2Sutureless and glue free conjunctival autograft technique is easy, safe, effective, prevents potential adverse reactions encountered with the use of foreign materials. This technique has an acceptable pterygium recurrence rate that is comparable to conventional sutured conjunctival autograft for primary pterygium.
