Wilcoxon signed rank test was used to compute statistical significance between mean preoperative and postoperative corneal astigmatism. Centroid values of SIA, preoperative astigmatism, and postoperative astigmatism were calculated using Cartesian coordinates based analysis. ![]() Keratometric ( ) readings were taken prior to surgery and at 12 weeks after surgery. All patients had operable cataracts and underwent superior approach MSICS. ![]() ![]() 58 eyes of 58 cataract patients with preoperative ATR astigmatism were involved in this study. The aim of the study was to report postoperative corneal and surgically induced astigmatism (SIA) in patients with preoperative against-the-rule (ATR) astigmatism who underwent superior approach manual small incision cataract surgery (MSICS).
