Phacoemulsification and zonular weakness: Contribution of the capsular tension ring with a thread

Abstract

Purpose: Cataract surgery in patients suffering from zonular weakness can be difficult and lead to severe complications. The insertion of capsular tension rings to stabilize the capsular bag along all steps of the phacoemulsification is an option, although can be difficult to remove intra-or post-operatively. A capsular tension ring with a thread is a safe alternative, which allows its easy removal at the end of the surgery. Patients and methods: Retrospective study of regular practice on 14 patients with zonular weakness who underwent phacoemulsification. Among them, 12 suffered from pseudo-exfoliative syndrome and 2 suffered from a post-traumatic cataract. All benefited from the use of a capsular tension ring with a thread during their surgery. Results: All surgeries were successful. Capsular tension ring with a thread was all removed at the end of surgery without any complication. Conclusion: The addition of a thread to the capsular tension ring is a simple modification that enhances its use by facilitating its intraoperative removal if necessary or at the end of surgery.
