We designed four prototypes of a capsular bag supporting ring for supporting and preserving postoperative integrity of the capsular bag, independently of the intraocular lens (IOL) implanted following continuous curvilinear capsulorhexis. An open poly(methyl methacrylate) ring, inserted experimentally in cadaver eyes through a 3.5 mm incision, adjusted well to various capsular bag sizes and could be implanted with common IOL types. Although some capsular shrinkage occurred in vitro, the roundness of the capsular bag equator was preserved, suggesting that the ring may help maintain postoperative capsular bag integrity.
