We describe a foldable acrylic intraocular lens (IOL) with distended haptics suitable for transscleral fixation and the insertion procedure. The IOL has an acrylic optic and poly(methyl methacrylate) haptics with a microscopic indentation 1.3 mm from the tip. Transscleral fixation of the IOL was performed through corneal incisions in 22 eyes, and surgical results were retrospectively assessed. The IOL was sutured firmly in position using the cow-hitch procedure, and there was no suture loosening to the distended haptic. The IOL design provided suitable fixation and may be indicated for bag fixation as well as transscleral fixation.
我们描述了一种带有扩张襻的可折叠丙烯酸人工晶状体 (IOL)，适用于经巩膜固定和插入手术。该 IOL 具有丙烯酸光学元件和聚甲基丙烯酸甲酯 (PMMA)襻，在尖端 1.3 毫米处有一个微观压痕。通过角膜切口在 22 只眼中进行了 IOL 的经巩膜固定，回顾性评估了手术结果。使用牛鼻结（cow-hitch）手术将 IOL 牢固地缝合固定在位，扩张襻没有松动。该 IOL 设计提供了合适的固定，可能适用于囊袋固定和经巩膜固定。
