In eyes with absent or insufficient capsule support, three-piece posterior chamber intraocular lens (PC IOL) may be fixed to the sclera. Previous techniques involve the use of sutures, flaps, glue, needles, trocars, or intrascleral tunnels to fixate the distal tips of the haptics intrasclerally. Herein we describe a modified technique for the sutureless scleral fixation of a standard 3-piece PC IOL using self-sealing sclerotomies created with a crescent blade and a 20-gauge microvitreoretinal blade, and then reinserting the haptics to leave the tips inside the vitreous cavity. We believe the relative simplicity of this technique makes it widely applicable for the placement of an IOL with insufficient capsule support.

通过触觉外在化和再内在化技术，通过自封式巩膜切开术伤口对人工晶状体进行无缝巩膜内固定。

对于没有或没有足够的囊膜支持的眼，可将三片式后房型人工晶状体（PC IOL）固定在巩膜上。先前的技术涉及使用缝合线，皮瓣，胶水，针头，套管针或巩膜内隧道将巩膜的触觉末端固定在巩膜内。在本文中，我们描述了一种改良的技术，该技术使用由新月形刀片和20口径微玻璃体视网膜刀片制成的自密封硬膜切开术，对标准3件式PC IOL进行无缝线巩膜固定，然后重新插入the具以将尖端留在玻璃体腔内。我们相信该技术的相对简单性使其广泛适用于囊支持不充分的IOL的放置。
