Abstract
The aim of the study was to analyze postoperative corneal astigmatism after phacoemulsification with intraocular lens implantation through a clear corneal incision. This prospective study included 22 eyes (10 right and 12 left eyes) having had phacoemulsification with implantation of a foldable intraocular lens through a clear corneal incision. A superotemporal incision was used in all right eyes, and superonasal incision in all left eyes. Astigmatism was measured by autorefractometer-keratometer preoperatively, and at 1 week, 1 month and 2 months postoperatively. The mean surgically induced corneal astigmatism was 0.23 D (diopter). The vertical component of astigmatism was statistically significantly lower postoperatively than preoperatively (p=0.0404). There was no significant difference in the horizontal component of astigmatism preoperatively and postoperatively (p>0.05). There was no statistically significant difference in surgically induced astigmatism between superotemporal incisions in the right eyes and superonasal incisions in the left eyes either (p>0.05). Oblique localization of clear corneal incision, superotemporal in the right eyes and superonasal in the left eyes, may ease manipulations during phacoemulsification for right-handed surgeon without significant difference in the surgically induced astigmatism.
