Clinical research of different surgical modes for the treatment of severe capsule contraction syndrome

Abstract

Objective To observe the clinical effect of different surgical methods for the treatment of severe capsule contraction syndrome. Methods Twenty-three eyes of 23 cases of severe capsule contraction syndrome were treated with operation. According to the condition of patients, 12 eyes underwent anterior capsulotomy with intraocular lens(IOL) adjustion in the capsule, 6 eyes underwent anterior capsulotomy with IOL ciliary sulcus fixation, and 5 eyes underwent IOL removal with vitrectomy and IOL ciliary sulcus suture fixation. The follow-up time was 3 months, and the visual acuity, anterior chamber reaction, position of intraocular lens, condition of the anterior and posterior capsule were measured respectively. Results The visual acuity improved postoperatively in all eyes. The size of the transparent area of the capsularhexis holes which underwent anterior capsulotomy significantly increased comparing with that before surgery. The complications such as glare and monocular diplopia in 6 cases disappeared after Nd: YAG laser posterior capsulotomy 1 month after the operation. Among the three different kinds of surgery procedures, postoperative best corrected visual acuity were all improved evidently one month after the surgery. The differences were statistically significant when compared with that of preoperation (P 0.05). Anterior chamber reaction of IOL ciliary sulcus suture fixation cases was the most obvious one, and it returned to normal within a week after appropriate treatment. The IOL were all centered in the capsule, and no other complication was observed during the follow-up of 3 months after operation. Conclusion Various surgical methods for severe capsular contraction syndrome are effective, satisfactory and safe.The right operation methods should be chosen according to the patients' condition.
