Abstract

Study Design: Randomized Interventional Prospective study was conducted in a tertiary eye care centre enrolling 300 patients of either sex having senile cataract (>40 years), who were distributed randomly in group A (operated with 2.2 mm incision) and group B (operated with 2.8 mm incision) with 150 patients in each group.
Pupose: To primarily compare surgically induced astigmatism (SIA) after 2.2 mm and 2.8 mm clear corneal incision in phacoemulsification cataract surgery
Method: Each patient underwent detailed evaluation and Uncorrected Visual acuity, Best corrected visual acuity and Keratometry was recorded pre operatively and on follow up visits at Post operative days 1, 7 , 21 & 42
Result: It was found that 2.2 mm incision induced a lesser amount of SIA as compared to 2.8 mm incision, although the difference was not statistically significant at all the follow-up visits.
Conclusion: Thus, reducing the incision size from 2.8 to 2.2 mm does not have a significant effect on SIA
