The eye is the window of the human body through which it feels its way and enjoys the beauty of the world. With all the possible modalities of cataract surgery, we try to give a normal vision. But Surgically Induced Astigmatism (SIA) is one of the causes of a poor quality of vision. We have studied SIA in 3 different sites of incision in Manual Small Incision Cataract Surgery (SICS). AIM: To compare between the surgically induced astigmatism(SIA) in small incision cataract surgery(SICS) by superior incision , temporal incision and supero-temporal incision. Materials and methods: Three hundred patients were studied. The patients were randomly assigned to any of three groups. The three groups had 100 patients each. The patients in group A underwent manual SICS with a superior incision, the patients in group B underwent manual SICS with a supero-temporal incision and the patients in group C underwent manual SICS with a temporal incision. The patients were examined on the postoperative days 1 and 7,1 month and 6 weeks. The uncorrected and the best-corrected visual acuity was recorded and a slit-lamp examination and auto-refracto-meter and keratometry examinations were also done. Statistics: All the calculations were performed by using vector analysis method. Statistical analysis was done by using descriptive and inferential statistics using Chi square test, One way ANOVA and Multiple comparison Tukey Test. Results: The mean SIA in group A was found to be 1.32± 0.97, in group B, it was 1.03± 0.75 and in group C, it was 1.00±0.60 . The p-value accordingly was < 0.001, which was highly significant. Conclusion: SICS which is done with a temporal and a supero-temporal approach provides a better quality of vision due to a significantly less SIA than the superior approach.
