Pterygium was recognised 3000 yrs ago. It was described by Susrutha way back in 1000 B.C. in India. Pterygium literally means “wing” and is an encroachment of the conjunctiva on the cornea, more often on the nasal side and is found in areas of high ultraviolet radiation, dry, hot, windy, dusty, and smoky environments. Aim: To compare the efficacy and safety of amniotic membrane graft as a viable alternative to conjunctival autograft in pterygium surgery. Material & Methods: To compare the efficacy and safety of amniotic membrane graft as a viable alternative to conjunctival autograft in pterygium surgery. Patients were randomly selected and divided into two groups of 35 each. Patients were randomly selected and divided into two groups of 35 each. SRI KRISHNA MEDICAL COLLEGE AND HOSPITAL, MUZAFFARPUR, BIHAR. Result: Out of the 70 patients included in the study, 67 patients (95.71%) had nasal pterygium, and 3 patients (4.29%) had temporal pterygium. Incidence of double headed pterygium was 0% Incidence of nasal pterygium was much higher than that of temporal pterygium. Conclusion: We conclude that both amniotic membrane graft and conjunctival autograft methods are equally effective treatment options for pterygium surgery, with comparable recurrence rates and cosmetic results and either may be selected based on the patient characteristics and the facilities available to the ophthalmologist
