Abstract
Corneal astigmatism is an issue of major concern in modern refractive cataract surgery. At least 20% to 25% cataract patients have a clinically significant amount of corneal astigmatism at preoperative evaluation. Over 90% of these have astigmatism ranging between 1.5 D to 2.5 D [1]. Residual astigmatism of more than 1.0 D after surgery can cause visual blurring and requires refractive correction with glasses [2] One popular approach to correct corneal astigmatism simultaneously during cataract surgery is by creating Limbal Relaxing Incisions (LRI) [3,4]. Another effective method is Toric IOL implantation [5].
