The endocapsular tension ring has helped in the management of patients with moderate loss of zonular support. However, the eye with profound zonular dialysis or weakness may require scleral fixation of the ring for centration and long-term stabilization. We used a new, modified endocapsular tension ring designed to provide scleral support without violating the integrity of the capsular bag in 4 patients. All patients had extreme loss of zonular support preoperatively or a significant risk of progressive zonular weakness. In each case, the new ring provided excellent support and centration of the capsular bag and intraocular lens intraoperatively and postoperatively.
囊内张力环有助于处理晶状体悬韧带中度缺失的患者。然而，对于存在严重晶状体悬韧带断离或松弛的眼，可能需要将该环巩膜固定以实现居中及长期稳定。我们在4例患者中使用了一种新的改良囊内张力环，其设计目的是在不破坏囊袋完整性的情况下提供巩膜支持。所有患者术前均存在晶状体悬韧带极度缺失或有晶状体悬韧带进行性松弛的显著风险。在每一例中，新环在术中和术后均为囊袋及人工晶状体提供了出色的支持和居中效果。
