Key result
The Henderson capsule tension ring is a modified open C-shaped loop with 8 indentations designed to improve the removal of nuclear and cortical material while maintaining capsular bag expansion.
The Henderson capsule tension ring is a modified device designed to facilitate the removal of nuclear and cortical material during eye surgery.
May aid cortical removal in complex cataracts; leaves open need for randomized comparisons versus standard rings.
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.
