| Abstract: Background: Pterygium is atriangular fibroelastic degeneration of the conjunctiva and subconjunctival tissue. Methods: quasi experimental study, comprising 52 patients aged from 35 to 60 during perid from April 2021 to April 2022 who underwent pterygium excision and autologus conjunctival graft. A total of 52 participants were enrolled and followed before and after 1 and 3 months after surgery by pentacam Scheimpflug camera . Results: there were significant changs in keratometric astigmatism at 1 month and 3 months compared with preoperative mean keratometric astigmatism, and there were statistically significant reduction in mean refractive astigmatism at 1 month and3 months postoperatively compared with preoperative mean refractive astigmatism. Also, a significant increase of spherical power of the cornea, there were statistically significant increase in average K1 at 1 month 3 months postoperatively compared with preoperative average K, There were statistically significant increase in average K 2 after 1 month,3 months, postoperatively compared with preoperative average K2, The mean BCVA was 0.31(0.13 SD) equivalent Decimal value preoperatively and improved significantly at 1 month postoperatively 0.48 (0.13 SD) equivalent Decimal value, P <0.001) and 3 months postoperatively 0.60( 0.13 SD), P <0.001) when compared with preoperative values. Conclusion: pterygium excision was associated with significant improvement in astigmatism. Keywords: Conjunctival degeneration, Graft surgery, Scheimpflug camera. | ||||
