Background: A comparative study to assesss the amount of changes in corneal astigmatism after pterygium excision by using two surgical techniques.  Materials and methods: Total of 60 cases diagnosed with primary pterygiumwere included in the present study and the patients are randomly allotted into two groups which has 30 in each group. Surgical technique include one group with ConjunctivalLimbalautograft with suture and the other group with ConjunctivalLimbalAutograftsutureless. All selected patients pre operatively  underwent detailed ocular examination which include visual acuity using Snellen's chart, anterior and posterior segment examination, grading of pterygium. Refraction recorded using auto refractometer .post operatively patients are assessed for visual acuity, refractometry on 1st week, 1month, 3month respectively and  results were analysed. Results: In the study 34 patients (56.6%) were male, 26 patients (43.3%) are female and age ranging from 15-55 years. The preoperative mean refractive astigmatism in suture group 2.55±1.23 and statistically decreased to 0.80±0.89D which was statistically significant (p<0.001), the preoperative mean refractive astigmatism in sutureless 2.03±1.17D decreased to 0.68±0.82D which was statistically significant (p<0.001). pre operatively mean visual acuity in suture group 0.59± 0.25 which improved to 0.87 ±0.17 which was stastistically significant(p=0.002). The preoperative mean visual acuity in sutureless group 0.63±0.24 which improved to 0.96±0.12 which was statistically significant (p=0.002). Conclusion:cpterygium excision results in significant reduction in astigmatism and improvement in visual acuity. Both surgical techniques are equally effective in reducing astigmatism and improvement of visual acuity.
