The application of capsular tension ring combined with iris hook in treatment of cataract with dislocated lens

Abstract

AIM: To discuss the application of capsular tension ring(CTR)combined with iris hook in treatment of cataract with dislocated lens. METHODS: Twenty-seven patients with 27 cataract-infected eyes combined with lens subluxation were treated phacoemulsification cataract surgery. With iris hook fixing capsular hole, CTR was implanted. The operation methods, postoperative vision, intraocular pressure, anterior chamber and intraocular lens location were analyzed. RESULTS: The operations were successfully completed for 25 patients with 25 cataract-infected eyes. The posterior capsule rupture and vitreous prolapse happened for the other 2 cases with 2 eyes. Between the 2 cases, 1 received ciliary sulcus implantation and the other anterior chamber intraocular lens implantation. The patients' vision was improved more or less. No serious complications happened. CONCLUSION: The application of CTR combined with iris hook in the treatment of cataract with lens dislocation can improve the procedure's operability and security, and reduce operation complications.
