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.
