We describe an ab externo, transscleral, intraocular lens (IOL) fixation technique using a surgeon-fashioned 25-gauge hook, a neodymium:yttrium aluminum garnet (Nd:YAG)-modified 27-gauge needle, and 9-0 polypropylene suture. This is a simple, inexpensive technique for creating small-gauge surgical instruments to accurately and atraumatically pass 9-0 and 10-0 polypropylene sutures through sclera. Holes, through which sutures can be threaded, are "burned" near the tips of 27-gauge or 30-gauge needles with an Nd:YAG laser. Using a fine needle holder, a 25-gauge hook is fashioned from a hypodermic needle. A surgical technique incorporating 2 ab externo incisions and achieving transscleral posterior chamber IOL fixation is discussed.
我们描述了一种经巩膜外的人工晶状体（IOL）固定技术，该技术使用外科医生制作的25号钩、钕：钇铝石榴石（Nd:YAG）改良的27号针和9-0聚丙烯缝线。这是一种简单、廉价的技术，用于制作小口径手术器械，以便准确且无创伤地将9-0和10-0聚丙烯缝线穿过巩膜。用Nd:YAG激光在27号或30号针的尖端附近“烧灼”出可穿入缝线的孔。使用精细持针器，用皮下注射针制作一个25号钩。本文还讨论了一种结合两个巩膜外切口并实现经巩膜后房型人工晶状体固定的手术技术。
