Secondary closure of posterior continuous curvilinear capsulorhexis

J Cataract Refract Surg. 1996 Nov;22(9):1200-5. doi: 10.1016/s0886-3350(96)80068-x.

Abstract

Purpose: To examine the hypothesis that removing the center of the posterior capsule would prevent posterior capsular opacification (PCO).

Setting: Department of Ophthalmology, University Hospital Antwerp, Belgium.

Methods: A posterior continuous curvilinear capsulorhexis (CCC) was done before intraocular lens (IOL) implantation in eyes at risk for PCO (uveitic, young adult), retinal detachment after neodymium:YAG (Nd:YAG) laser capsulotomy (highly myopic) or for cystoid macular edema (uveitic, diabetic) and in eyes in which the posterior capsule was opaque intraoperatively. The 51 eyes of 40 patients had a follow-up ranging from 6 months to 2 years.

Results: Four eyes (8%) developed partial closure of the posterior CCC without vision impairment; 6 eyes (12%) had total closure, of which 2 (4%) had a loss of two or more Snellen lines necessitating an Nd:YAG laser capsulotomy.

Conclusion: Young adult eyes and eyes with underlying diabetic retinopathy or uveitis are at risk for total closure of the posterior CCC. Only young adult eyes required Nd:YAG laser capsulotomy after the posterior CCC.
