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.
我们设计了四种囊袋支撑环原型，用于在连续环形撕囊术后支撑并保持囊袋的完整性，与所植入的人工晶状体无关。一种开放式聚甲基丙烯酸甲酯环，通过3.5毫米切口实验性地植入尸体眼中，能很好地适配各种囊袋尺寸，并且可与常见类型的人工晶状体一同植入。尽管在体外出现了一些囊膜收缩，但囊袋赤道的圆度得以保持，这表明该环可能有助于维持术后囊袋的完整性。
