Effects of Corneal Incision on Steep Meridian with Preexisting Astigmatism in Cataract Surgery by Phacoemulsification

A cross-sectional, descriptive study was conducted in the Department of Ophthalmology, Combined Military Hospital (CMH), Dhaka Cantonment, Bangladesh, between November 2017 and May 2018, to assess keratometric results clear corneal incision on steep meridian patients with preoperative astigmatism during phacoemulsification cataract surgery. After obtaining written informed consent, a total 40 age ranged 70 years were selected. All examined pre- postoperatively after 1 week 3 months for evaluation astigmatism. Keratometry done by using an autorefractometer autokeratometer. Astigmatism calculated from data vector analysis. The mean participants 52±9.1 years. Male predominance observed as male-female ratio 1.7:1. change post-operative 0.44±0.20 temporal group 0.19±0.00 superior group; both statistically significant (P<0.001). difference groups 0.375 Postoperative <0.5D 16(40%) when given at site 8(20%) site. significantly (P<0.05) decreased more comparison Our suggest that preexisting majority placed has less surgically induced than incision.
