Abstract

The data presenting preoperative astigmatism in cataract patients ,who are scheduled for cataract surgery has been presented in only few studies.. This study which comprises of data of 700 cataract patients was undertaken to investigate preexisting corneal astigmatism in adult patients with cataract. We analyzed keratometric readings acquired by manual bausch-lomb keratometry before surgery between march, 2012 and December, 2014. There were 700 patients aged between 25and 93 years involved with a Male to female ratio of 1.08:1. Mean keratometry in diopters was K1 = 43.25 and K2 = 43.75. Mean corneal astigmatism was 1.16 diopter and a majority (45.92%) of eyes had astigmatism between 1.00 and 1.99 diopters. Two-thirds of the eyes (66.9%) in this study had preoperative corneal astigmatism equal to or above 1.00 diopter. Findings will help local cataract surgeons to estimate the potential demand for toric intraocular lenses.
