A Modified Girth-Hitch Suture Technique to Rescue Single-Haptic Dislocation of Scleral-Fixated Intraocular Lenses.

Abstract

To describe the technique of modified girth-hitch suture for one-side transscleral fixation to rescue a single-haptic dislocation. In this surgical technique report, dislocated scleral-fixated posterior-chamber intraocular lenses (IOLs) were secured to the sclera using a 10-0 polypropylene suture looped around the IOL haptic. Three types of IOL were secured in this study (four cases of one-piece polymethyl methacrylate (PMMA) IOL, one case of three-piece acrylic IOL with PMMA loop, and one case of acrylic foldable IOL with a two-plate loop design). Six patients, who had subluxation of the scleral-fixated posterior-chamber IOL due to single-knot dehiscence, underwent refixation of scleral-fixated IOL surgery using this technique. In all cases, successful repositioning with stable and central fixation of the IOLs was achieved. No intraoperative or postoperative complications were noted. Internal refixation with a girth-hitch suture is a relatively quick and convenient method for the management of a dislocated IOL haptic on one side.
