The next common age group was 66-75 years(31 patients-38.75%). In the superior MSICS group, the majority of patients (28 patients-70%) had a moderate post-operative unaided visual acuity of 6/18-6/12. In the temporal MSICS group, majority of patients(33patients-82.5%) had a good post-operative unaided visual acuity of 6/9-6/6. The mean surgically induced astigmatism(SIA) in the superior MSICS group was 1.12 and in the temporal MSICS group was 0.45 with a difference of 0.67. The SIA values were analyzed using the unpaired T-test which showed a value of 9.967 which was statistically significant(P value of 0.0001).Conclusion: This study has shown that the temporal approach for Manual small incision cataract surgery(MSICS) has less postoperative astigmatism and better postoperative unaided visual acuity compared to the superior approach.
