The forceps-needle: Combining needle and grasping functions in a single instrument

Abstract

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.
