Purpose:
To describe the technique of modified girth-hitch suture for one-side transscleral fixation to rescue a single-haptic dislocation.
Methods:
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).
Results:
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.
Conclusion:
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.
