Abstract :

The aims of modern cataract surgery are rapid visual rehabilitation, the best possible uncorrected visual acuity and minimal postoperative astigmatism. Surgically induced astigmatism (SIA) is still a common obstacle for achieving excellent uncorrected visual acuity. In this comparative retrospective study, 150 patients that were underwent phacoemulsification with implantation of foldable posterior chamber intraocular lens(PCIOL) in eye department of our institute which were divided into 3 groups of 50 patients including temporal(Group A), superotemporal(Group B) and superior (Group C) clear corneal incisions. These patients were evaluated on day 1, 1st week,3rd week and at the end of 6th week. In present study shows a mean surgically induced astigmatism (SIA) at the end of 6 weeks after cataract surgery following temporal incisions was 0.68D, that following supero–temporal incisions was 0.96D & following superior incisions was 1.5D. This implies that temporal ( Group A) and supero–temporal (Group B) incisions cause less surgically induced astigmatism as compared to superior (Group C) incisions. There was no statistically significant difference in SIA between temporal(Group A) and supero–temporal (Group B) incisions.
