Control of postoperative astigmatism.

Thirty-six eyes with excessive astigmatism following cataract extraction via a corneal section were subjected to suture adjustment. This was performed six to eight weeks postoperatively under topical anaesthesia. The cases were selected from a large volume of corneal section cases because they had over 3.0 dioptres astigmatism. We reduced astigmatism significantly in the majority. There were no serious complications.
