Abstract
Abstract: Most, if not all, ophthalmologists strive to achieve a round pupil after cataract surgery with posterior chamber lens implantation. The presence of pupil abnormalities and iris modifications is cosmetically undesirable and may affect the quality of postoperative vision. The pupillary motility may be changed which will in turn affect both pupillary light reflexes and pupillary dilatation during fundus examination. In this paper, we prospectively studied 2 groups of patients who underwent uncomplicated cataract surgery with posterior chamber lens implantation; 100 patients who had planned extracapsular cataract extraction (ECCE), and 130 patients who underwent phacoemulsification. On the first postoperative day, we found a 16% rate of pupil abnormalities in the group which underwent ECCE surgery while only 5.3% of the phacoemulsification group had pupil abnormalities. There were different causes in which the two groups. The most common cause of pupil abnormality after ECCE was due to iris sphincter rupture, whereas the most common cause after phacoemulsification was due to iris trauma during phacoemulsification. These pupil abnormalities are the direct consequence of factors in surgery and we suggest ways to minimize the occurrence of such abnormalities in cataract surgery.
