A new forceps-needle to facilitate intrascleral haptic fixation surgery is described. In an initial series of 10 cases, the forceps-needle was used to grasp and externalize the haptic of a 3-piece intraocular lens (IOL) for transscleral fixation. The site of perforation was marked at 180 degrees 2.0 mm away from the limbus. Then, the IOL with polypropylene haptics was folded and implanted partially into the anterior chamber. A transconjunctival, scleral tunnel of about 2.0 mm length parallel to the limbus was prepared with the forceps-needle on 1 side, with the second hand holding the leading haptic through a side-port incision. The end of the first haptic was grasped and externalized after which the end of the haptic was flanged. Subsequently, a second scleral tunnel was prepared with the forceps-needle, and the second haptic was externalized and flanged. All procedures could be performed without any intraoperative complication.
描述了一种用于促进巩膜内触觉固定手术的新型钳针。在最初的10例病例系列中，使用该钳针抓取并将三片式人工晶状体（IOL）的触觉部引出以进行经巩膜固定。穿孔部位标记在距角膜缘180度、2.0毫米处。然后，将带有聚丙烯触觉部的IOL折叠并部分植入前房。用钳针在一侧制备一条与角膜缘平行的约2.0毫米长的经结膜巩膜隧道，另一只手通过侧切口握住前端触觉部。抓取并引出第一个触觉部的末端，然后将触觉部的末端翻边。随后，用钳针制备第二条巩膜隧道，引出第二个触觉部并翻边。所有手术过程均未出现任何术中并发症。
