Abstract: Background: Pterygium is seen to affect refractive status of the eye, cause astigmatism and can thus have significant impact on vision. Aim: To study changes in astigmatism before and after pterygium surgery with conjunctival autograft. Methods: The prospective cross - sectional study was conducted in department of Ophthalmology, in a Tertiary care center in 200 cases of pterygium of age 20 - 75 years attending O. P. D. over a period of 2 years. Data will be analysed using appropriate software. Results: Maximum occurrence of pterygium was in the 41 - 50 years age group.49 %of the affected male and 51 % affected females in the entire study group. Left eye was more involved and also nasal side. Among the study group, 13 patients had grade 1 pterygium, 164 patients had grade 2 pterygium and 23 patient had grade 3 pterygium. Majority were farmers. In the present study, pterygium was more common in persons engaged in outdoor occupations like farmers and they make upto 108 out of the total 200 cases (54 %). Mean astigmatism was more in higher grades of pterygium. Visual acuity was improved significantly after pterygium excision surgery. Conclusion: Pterygium is associated with significant astigmatism in most cases. that can be reduced by surgical excision. resulting in improvement of visual acuity with less complicationsin conjunctival autograft techniques.
