Abstract: Purpose: To compare the Astigmatic changes before and after pterygium excision with conjunctival limbal autograft transplant. To observe for recurrence of pterygium after surgery. Methods: A prospective interventional study included 31 eyes of 31 patients diagnosed with pterygium. All participants underwent pterygium excision with conjunctival limbal autograft transplantation and were examined pre - operatively and post - operatively (1st month post intervention). Evaluation included best corrected visual acuity and corneal astigmatism. Paired t - test was used for statistical analysis. They were also followed up for 6 months and observed for recurrence. Results: There were 31 eyes of 31 patients aged 28 - 61 years. The mean age was 39.096 ? 12.38 years. The mean value of pre - operative astigmatism was 1.177 ? 1.02 D Cylinder while that for post - operative astigmatism was 0.58 ? 0.50 D cylinder (p<0.01). Post - operative best corrected visual acuity significantly increases after surgery (p<0.01). Conclusion: The astigmatic changes induced by pterygium reduces significantly following surgical excision and provides visual and cosmetic improvement. This study also confirmed that Conjunctival limbal autograft was successful in preventing pterygium recurrence.
