Surgical techniques for repositioning a dislocated intraocular lens, repair of iridodialysis, and secondary intraocular lens implantation using innovative 25-gauge forceps.

Abstract

We developed surgical techniques for the sulcus fixation of a posteriorly dislocated or secondarily implanted posterior chamber intraocular lens, repair of an iridodialysis, and the management of a decentered intraocular lens during vitreous surgery using innovative 25-gauge forceps. The 25-gauge forceps have a curved shaft, a tip with a distal platform for grasping a suture, and a proximal groove for gripping a haptic. The forceps are inserted through a grooved scleral incision into the plane of the ciliary sulcus, facilitating manipulations such as fastening a suture loop around a haptic, repositing an intraocular lens at the ciliary sulcus, and grasping sutures during repair of a iridodialysis or implantation of a secondary intraocular lens. Seven patients underwent vitreous surgery using the new forceps. In all seven patients the surgical objectives were accomplished with the 25-gauge forceps without postoperative complications such as hemorrhage, hypotony, or lens decentration. The 25-gauge forceps are innovative instrumentation designed specifically for anterior segment applications during vitreous surgery.
