A One Year Cross-Sectional Study to Measure Surgically Induced Corneal Astigmatism in Superior Frown Small Incision Cataract Surgery in Senile Cataract Patients

Abstract

BACKGROUND AND OBJECTIVES: ABSTRACT To measure surgically induced astigmatism in senile cataract patients undergoing superior frown incision SICS (6mm) without sutures at Prabhakar Kore’s KLES Hospital, Belgaum. METHODS: This was a prospective cross-sectional study in which Manual superior frown incision SICS (6mm) was carried out in 150 consecutive patients having senile cataract. The patients were followed up on the 30 x th day of operation .Surgically induced astigmatism was calculated using the pre-operative and post-operative keratometry readings by vector method (SIA software) using appropriate statistical analysis RESULTS: The mean surgically induced astigmatism in 150 patients undergoing superior frown incision (6mm) SICS was + 0.51 D +/- 0.24 D 180 (ATR) CONCLUSION: Surgically induced astigmatism in patients undergoing superior frown incision (6mm) SICS was less leading to better uncorrected visual acuity( UCVA )in the post-operative period. ATR astigmatism was induced in the majority of the cases
