Abstract :

 Objective: to study the impact of pterygium surgery on pterygium induced astigmatism in patients visiting G.G.G Hospital Jamnagar. Methods: Hospital based study conducted in the Department of Ophthalmology of G.G.G.Hospital,Shri M.P.Shah medical college,Jamnagar during may 2015–april 2016. A total of 25 patients of primary pterygium who underwent pterygium excision surgery using bare sclera technique were studied.. Detailed pre–operative and post–operative examination was carried out precisely. The effect of surgery on astigmatism was evaluated 1 month after the surgery and the preoperative and the post operative results were compared. Type of surgery :hospital based cross–sectional study. Result: Majority of the patient were from 41 to 65 years of age.There was significant reduction of astigmatism after pterygium surgery. There was significant improvement in visual acuity after pterygium surgery. The mean preoperative refractive cylinder was 3.00 ± 1.0358D, which improved to 1.43 ± 0.6752(P =<0.0001) postoperatively. The mean visual acuity preoperatively was 0.3812 ± 0.1159 D which improved to 0.6628 ± 0.1738 D (P < 0.0001) postoperatively. The willingness of the patients for pterygium surgery is highest in grade II pterygium (52%) with female preponderance(69.23% out of 13 patients having grade II pterygium).Grade II and III show female preponderance to get pterygium operated (36% of grade II pterygium and 32% of grade III pterygium out of 25 patients). The amount of astigmatism was seen to increase with the grade of pterygium . Conclusion: The present study verifies that successful pterygium excision surgery reduces the pterygium induced refractive astigmatism and improves the visual acuity
