Comparision of surgical induced astigmatism between sics superior and sics temporal

Abstract

Purpose: The aim of this study was to analyze the surgically induced astigmatism in comparison to site of incision superior and temporal in commonly performed SICS technique of cataract surgery. Materials and Methods: A prospective interventional study was done on 30 patients who underwent manual small incision cataract surgery (MSICS) divided into two groups namely sics superior group and sics tempral group based on incision-site. The two techniques were compared with respect uncorrected visual acuity, surgically induced astigmatism and type of astigmatism drift. Result: In our study, There was significant difference between techniques regarding best uncorrected visual acuity on 40th post operative day. Greater proportion of patients had good outcomes in both the groups as regards to final visual acuity. Superior incision induced post operative ATR drift (75%) and temporal incision induced WTR astigmatism (70%). Conclusion: Incision on steep axis is an economical and effective way of reducing pre-existing astigmatism in high-volume and low-cost cataract surgery.
