Comparison of Pre and Postoperative Astigmatism after Cataract Extraction by Phacoemulsification through a 3.2 MM Clear Corneal Superotemporal Incision

Material and Methods: A prospective study was performed on 144 eyes of 132 patients. They were operated upon for cataract between 12/01/2007 and 31/12/2012 by a single eye surgeon at a private set up. Follow up period was from 6 month to five years (mean 33 months). The patients included in this study, underwent cataract surgery by phacoemulsification through 3.2 mm superotemporal clear corneal incision. Their mean age at the time of surgery was 50.5 years (range: 25 to 76 years). They were divided into two groups depending upon, “With the Rule” (Group A) or “Against the Rule”(Group B), pre operative astigmatism.
