This paper introduces a surgical technique for the sutureless management of zonular dialysis greater than 120° using a capsular tension segment (CTS) or a modified capsular tension ring (m-CTR; CTR with suturing eyelets) and a haptic removed from a 3-piece polypropylene IOL.
A CTR is used as normal. Cataract removal is followed by connection of the CTS or m-CTR to the single haptic and created using heat to make a flange in one haptic's extremity. The other extremity is placed in the CTS or m-CTR's central hole. The CTS or m-CTR/flanged-haptic complex is introduced into the capsular bag and aligned with the weakest zonular quadrant. A 30-gauge needle guides the externalization of the free haptic extremity through the adjacent pars plana and creates a flange on the second haptic tip permitting intrascleral fixation of the CTS or m-CTR.
The result is a successful IOL implantation with a sutureless technique.
This double-flanged m-CTR/CTS technique allows suture-free option for managing zonular weakness or dialysis while performing cataract surgery.
本文介绍一种手术技术，用于使用囊袋张力节段（CTS）或改良的囊袋张力环（m-CTR；带有缝合孔眼的CTR）以及从三件式聚丙烯人工晶状体上取下的襻，对大于120°的悬韧带离断进行无缝合处理。
按常规使用CTR。白内障摘除术后，将CTS或m-CTR连接到单个襻上，并通过加热在一个襻的末端制作一个凸缘。将另一端置于CTS或m-CTR的中心孔中。将CTS或m-CTR/带凸缘襻复合体引入囊袋，并与最薄弱的悬韧带象限对齐。一根30号针引导游离襻末端通过相邻的睫状体平坦部穿出，并在第二个襻尖端制作一个凸缘，从而实现CTS或m-CTR的巩膜内固定。
结果是通过无缝合技术成功植入人工晶状体。
这种双凸缘m-CTR/CTS技术在进行白内障手术时，为处理悬韧带薄弱或离断提供了无缝合选择。
