Refractive changes with corneal incision 2.8mm after phacoemulsification

: There are numerous techniques for dealing with astigmatism both during and after cataract surgery. Good uncorrected post-operative distance visual acuity can be obtained for high percentage of cataract patients with pre-existing corneal astigmatism. The goal of this study is to determine the keratometric change and resultant post-operative refraction of routine cataract patients, after a clear corneal incision of 2.8mm on the steeper meridian. Place and Duration of Study: This was a general free hospital-based prospective study. The study was started from May 2016 and was completed by May 2018. Methodology : A total of 30 cataract patients were included in this study. Pre-operative keratometric readings were compared with postoperative readings, after a clear corneal incision (CCI) of 2.8mm made during phacoemulsification procedure. Results : Patients were monitored for four weeks post-operatively. A total of thirty eyes underwent phacoemulsfication cataract surgery with clear corneal incision on steep axis had mean residual astigmatism of 0.45 D and SD achieved 0.58.
