Management of subluxated cataracts is challenging, especially in cases with more than 5 clock hours of subluxation. Capsular bag stabilising devices are of utmost importance in these cases. We report two cases of post-traumatic lens subluxation of more than 6 clock hours, in which the bag was stabilised intraoperatively using two capsular tension rings (CTRs) placed diametrically opposite to each other, in place of the conventional Cionni ring. Slow phacoemulsification was done followed by intraocular lens (IOL) implantation. Postoperatively, the IOLs were found to be well centred. Also, the use of two CTRs maintains the shape of the capsular bag and prevents lens epithelial cell migration and capsular cocontraction.
外伤性晶状体半脱位超过 6 小时，囊袋稳定性至关重要。我们报告了两例外伤性晶状体半脱位超过 6 小时的病例，术中使用两个对置的囊袋张力环（CTR）稳定囊袋，替代传统的 Cionni 环。采用缓慢的超声乳化术，然后植入人工晶状体（IOL）。术后发现 IOL 位置居中。此外，使用两个 CTR 可维持囊袋形状，防止晶状体上皮细胞迁移和囊袋挛缩。
