Comparison of Visual Acuity and Surgically Induced Astigmatism after Phacoemulsification by Temporal Clear Corneal Incision & Superior Clear Corneal Incision

Abstract

Background- The primary goal of cataract extraction surgery is immediate visual recovery and the best uncorrected visual acuity (UCVA) post operatively. Aim: To compare the surgically induced astigmatism (SIA) after phacoemulsification surgery with superior clear corneal incision (SCCI) and temporal clear corneal incision (TCCI). Materials & method: 11 articles were reviewed on PubMed related to SIA & a review was made on the factors that are responsible to reduce the post-operative astigmatism. The outcome measures were SIA and UCVA at 2 and 6 weeks, post‐operatively. Results - In this study we expect to have better visual outcome and reduce incidence of SIA in TCCI than SCCI. Conclusion: TCCI appears to have better visual outcome and reduced incidence of SIA.
