Abstrakt: Objective: To compare visual outcomes and differences in surgically induced astigmatism between superior and supero-temporal incisions in manual small incision cataract surgery (MSICS). Study Design: Quasi-experimental study. Place and Duration of Study: Combined Military Hospital, Rawalakot Pakistan, from Jan to Jun 2017. Methodology: Sixty patients were selected and divided into two groups of 30 patients each. One Group was given a superior incision, the other was made the supero-temporal incision, and Manual small incision cataract surgery was performed. Preoperative and postoperative visual acuity, keratometry and refractive data were collected for all patients. In addition, surgically induced astigmatism (SIA) was analysed using a line SIA calculator. Results: The mean age of our patients was 59.57±10.13 years. Post-operatively, the visual acuity significantly improved in both groups. Mean induced astigmatism due to surgery came out to be 0.75±0.44 D for the superior incision and 0.45±0.18 D for the supero-temporal incision. The study found that in the Superior Incision-Group, induced astigmatism was slightly higher than in the Supero-Temporal-Group. Moreover, the Supero-Temporal-Group had a better uncorrected visual outcome than the Superior Incision-Group. Conclusion: Overall, manual small incision cataract surgery has good visual outcomes. Manual small incision cataract surgery through supero-temporal incision was found to have a better visual outcome with less surgically induced astigmatism than the superior incision.
