description Objective: Globally a significant proportion of treatable blindness is caused by cataract, especially in India and southeast Asia. Treatment of cataract is surgical correction with intraocular lens implantation. The main drawback of surgical correction is induction of postoperative astigmatism in patients. The aim of this study was to compare the degree of astigmatism in manual small incision cataract surgery and phacoemulsification 3 mo postoperatively Methods: The study was a retrospective case study on postoperative corneal astigmatism after cataract surgery. It was conducted in a tertiary care hospital in Thandalam, Tamil Nadu. A total of 100 patients were selected and divided into two groups, group A (=50) underwent phacoemulsification and group B (=50) underwent manual small incision cataract surgery. Preoperative astigmatic status of the patients was noted from patient records. Both groups were evaluated 3 mo postoperatively using automated keratometry. The data collected was analyzed using Microsoft Excel Independent T test, p
