A Comparative study to evaluate visual outcome in Post-operative patients of small incision cataract surgery and phacoemulsification

Abstract

A comparative study to evaluate visual outcome in post-operative patients of Small Incision Cataract Surgery and Phacoemulsification. Design: A prospective, comparative hospital based interventional study was conducted on 1450 eyes having visually significant senile cataract undergoing cataract extraction surgery by either of two methods visSmall Incision Cataract Surgery or Phacoemulsification at Department of ophthalmology, Era University, Lucknow. A detailed post-operative examination was carried out on first post-operative day, then follow-up of patients of both the study groups (SICS and Phacoemulsification) regarding BCVA was carried out in Eye O.P.D. on 7th, 15th, 30th and 45th day. Results: There was no significant difference between the SICS & Phacoemulsification in terms of BCVA at Post-Operative 15 days month, Post-Operative Spherical Refraction at 15 days (p = 0.693) and 45 days (p = 0.640). But there was significant difference between two groups in terms of Cylindrical Refraction at Post-Operative 1 Week) (p=<0.001) and at 1 Month (p = <0.001) with the median Post-Operative Cylindrical Refraction higher in MSICS group at 1 week & 1 Month. The median Post-Operative Cylindrical Refraction difference is all due to the fact that SICS had larger surgical incision causing higher surgically induced astigmatism. Conclusions: Phacoemulsification gives better uncorrected visual acuity (UCVA) at post-operative day 45 days and better BCVA at 1week and Post- Operative Cylindrical Refraction at 15days and at 45 days. Whereas, BCVA at 45daysare similar in both the study groups SICS andPhacoemulsification.
