The treatment for capsular contraction syndrome

Abstract

Objective To investigate the treatment method for capsule contraction syndrome after cataract phacoemulsification. Methods A series of 19 eyes of 19 cases with capsule contraction syndrome after cataract phacoemulsification were investigated. Patients in incipient and progressive stage of capsule contraction syndrome were treated by Nd: YAG laser anterior capsulotomy, and severe ones were treated by capsulolysis. The postoperative best corrected visual acuity, anterior chamber reaction, anterior capsule status, location of IOL and intraocular pressure(IOP) were observed during following up period of 1 to 6 months. Results The best corrected visual acuity after operation were significantly improved in all cases comparing with that before the operation, and the difference was statistically significant(P 0.05). The difference of IOP between postoperative 1 month and 6 month was not statistically significant either(P>0.05); The difference of postoperative IOP between Nd: YAG laser anterior capsulotomy and anterior capsulolysis was not statistically significant (P>0.05). The diameter of anterior capsular optical zone ranged from 5.5 to 6 mm. All intraocular lens situated within the capsular bag without decentration or tilt. Anterior chamber reaction was mild. No capsular rupture, zonule tears or other severe complication were observed. Conclusion Nd: YAG laser anterior capsulotomy and capsulolysis are safe and effective for the treatment of capsule contraction syndrome. Nd: YAG laser anterior capsulotomy is suitable for the treatment of incipient and progressive stage of capsule contraction syndrome. The capsulolysis is suitable for the treatment of severe capsule contraction syndrome. Key words: Syndrome, contraction, capsule; Capsulotomy, anterior, Nd: YAG laser; Capsulolysis
