Post-Operative Astigmatism After Sics and Phacoemulsification

Astigmatism plays a major role in post-operative compliance after cataract extraction surgery. Recent advances in technology and intra ocular lens implantation through small incision allow early rehabilitation of patient and limits excessive post-operative astigmatism. Material and methods: patients undergoing cataract extraction were considered for the study. 80 patients were taken for the study, 40 in each group of SICS and phacoemulsification. In all cases follow up visits thorough ocular examination was done especially looking for corrected visual acuity & correction needed for that. Keratometry was done in each follow up visits. At the end of three months surgically induced astigmatism (SIA) was calculated by deducting pre-operative astigmatism from the post-operative astigmatism.

The less average SIA was noted in phacoemulsification group than in small incision cataract surgey. For SIA operative factors like incision size, shape, type, length, and location play a major role.
