Radial anterior capsular tears frequently occur in posterior-chamber iris-plane phacoemulsification cases. These tears extend to the capsular bag equator and can allow the knee of an in-the-bag posterior chamber intraocular lens (IOL) to unfold a smaller anterior capsular remnant. This unfolding can allow the knee of the IOL loop to extend beyond the capsular equator, leading to IOL decentration. Typical anterior capsular radial tear configurations along with guidelines for IOL design selection and orientation after recognition of these tears are presented. Proper IOL centration was achieved in 255 of 262 patients (97%) in a study observing these guidelines.
在前房虹膜平面白内障超声乳化手术病例中，前囊膜放射状撕裂经常发生。这些撕裂延伸至囊袋赤道部，可使囊袋内后房型人工晶状体（IOL）的襻展开较小的前囊膜残余部分。这种展开可使IOL襻的襻脚延伸至囊袋赤道部之外，导致IOL偏心。本文介绍了典型的前囊膜放射状撕裂形态以及识别这些撕裂后IOL设计选择和定位的指导原则。在一项遵循这些指导原则的研究中，262例患者中有255例（97%）实现了IOL的正确居中。
