Modified capsular tension ring for cortical removal after implantation

Abstract

We describe a modification of the original 14C Morcher capsular tension ring. The new ring, the Henderson capsule tension ring (HCTR, Morcher), is an open C-shaped loop made of poly(methyl methacrylate). It has 8 equally spaced indentations of 0.15 mm to improve the ease of removing nuclear and cortical material while maintaining equal expansion of the capsular bag. The HCTR is currently under review by the U.S. Food and Drug Administration.
