Purpose: To investigate the influence of capsular tension ring (CTR) on prevention of intraoperative complications due to zonular weakness and increased capsular fragility during phacoemulsification of cataracts with pseudoexfo­liation. Materials and methods: 148 eyes of 148 patients who had cataract with pseudoexfoliation underwent pha­coemulsification surgery included. 74 eyes of the first group (study group) were implanted with CTR after hy­drodissection, while CTR was not performed in 74 eyes of control group (Group 2). In both groups, intraoperative complications such as zonular dialysis, conversion to ex­tracapsular cataract extraction (ECCE) or intracapsular cataract extraction (ICCE), posterior capsular rupture, vitreus loss, and early postoperative complications were recorded and compared between two groups. Results: In group 1, no complication occurred in 64 eyes (86.5%) and intraocular lens (IOL) implanted in the bag. In 10 eyes (13.5%) posterior capsule rupture occurred, in 4 of them converted to ECCE, IOL implanted in four eyes. In other 6 eyes, phacoemulsification completed un­derlay viscoelastic. In group 2, no complication occured in 42 eyes and IOL implanted in the bag. In 10 patients (13.5%) zonular dialysis occurred, in 4 of them IOL im­planted in the bag and in 6 of them converted to ICCE and IOL implanted in anterior chamber. Posterior capsule rup­ture occurred in 20 eyes (27.0%), all of them converted to ECCE and IOL was implanted. In 2 eyes capsullorrhexis occurred and converted to ECCE, IOL was implanted in sulcus. Conclusion: In patients with pseudoexfoliation, CTR im­plantation in phacoemulsification simplified the surgery, increased the rate of IOL implanted in the bag and pre­vented complications like IOL desantralization after sur­gery.
