Anterior capsular phimosis in eyes with a capsular tension ring.

A 64-year-old woman with zonular weakness in the left eye and a 79-year-old man with bilateral pseudoexfoliation and intraoperative zonular dehiscence had phacoemulsification with in-the-bag implantation of a single-piece poly(methyl methacrylate) intraocular lens (IOL) and a capsular tension ring. Ten to 12 weeks postoperatively, all 3 eyes developed significant visual loss secondary to capsule shrinkage and occlusion of the capsulorhexis opening. All eyes had a neodymium:YAG laser radial anterior capsulotomy, anterior capsulectomy, or both. Visual acuity was restored in all eyes despite slight IOL decentration.

Capsulorhexis phimosis in retinitis pigmentosa despite capsular tension ring implantation.

A 56-year-old man with retinitis pigmentosa presented with dense nuclear sclerosis and scattered zonular loss with laxity confirmed by ultrasound biomicroscopy. He had extracapsular cataract extraction with a 6.0 mm continuous curvilinear capsulorhexis and implantation of a capsular tension ring (CTR) and a single-piece poly(methyl methacrylate) (PMMA) intraocular lens (IOL) in the capsular bag in his left eye. Severe anterior capsule fibrosis and contracture of the capsulorhexis opening with nasal decentration of the IOL were noted 4 months after surgery. A neodymium:YAG (Nd:YAG) laser anterior capsulotomy was performed to prevent further zonular stress and IOL decentration. The centripetal forces of capsular fibrosis after cataract surgery may exceed the centrifugal resistance of the standard CTR and PMMA IOL in patients with retinitis pigmentosa. Such patients must be carefully monitored postoperatively. An Nd:YAG laser anterior capsulotomy is a safe and effective option to manage anterior capsule fibrosis.
