Reduction of astigmatism following cataract surgery.

This study documents the induced corneal astigmatism following cataract surgery. All patients developed significant astigmatism with the rule which decreased with time and following division of sutures. Corneal incision induced a significantly higher degree of astigmatism than limbal incision, but this difference was negated by suture division. There were no cases of wound dehiscence following division of sutures. Suture division is therefore recommended as a method of reducing astigmatism following cataract surgery.
