A COMPARATIVE STUDY ON THE SUPERIOR, SUPEROTEMPORAL, AND TEMPORAL INCISION IN MANUAL PHACOEMULSIFICATION FOR POSTOPERATIVE ASTIGMATISM

Abstract

Aim: To compare the amount of astigmatism in superior, superotemporal, and temporal incisions in manual phacoemulsication. Methods: Three hundred patients were studied. The patients were randomly assigned to any of the three groups. The three groups had 100 patients each. The patients in group Aunderwent manual phaco with a superior incision, the patients in group B underwent manual phaco with a supero-temporal incision and the patients in group C underwent manual phaco with a temporal incision. The patients were examined on postoperative days 1,7,21 and 45. The uncorrected and the best-corrected visual acuity was recorded and a slit-lamp examination and autorefractometer and keratometry examinations were also done. Results:The mean SIAin group Awas found to be 1.572 ± 0.651, in group B, it was 0.532 ± 0.317and in group C, it was 0.435 ± 0.338. The F score which was applied was found to be 186.44. This value was more than the standard value. The p-value accordingly was < 0.001, which was highly signicant. Conclusion: Manual phaco which is done with a temporal and a supero-temporal approach provides a better quality of vision due to a signicantly less SIAthan the superior approach.
