Abstract

Purpose:: To report the feasibility and advantages of the 25-Gauge Pars Plana Vitrectomy (PPV) along with the Modified McCannel Iris-Suture Fixation (MMIF) Technique for dislocated Posterior Chamber Intraocular Lenses (PC-IOL) .

Methods:: A retrospective chart analysis of 16 consecutive eyes with dislocated PC IOL's managed with 25 gauge PPV and MMIF of the dislocated PCIOL was carried out. Preoperative and postoperative visual acuities as well as detailed anterior and posterior segment examinations were carried out in all cases. Following a 25 gauge pars plana vitrectomy, the dislocated IOL was grasped and the optic brought into the anterior chamber and "captured" there. Then a 10-0 Prolene suture on a long tapered needle was used to suture both haptics to the iris with the MMIF technique. All eyes were serially followed up for at least three months post-operatively.

Results:: 14 eyes had visual improvement of 4 lines or more following surgery. Two eyes did not improve due to macular diseases. The suture-fixated PC-IOLs remained stable and well-centered in 15 eyes. One eye had a dislocation of the IOL after blunt trauma 1 year post surgery, and re-operation was required. Complications such as persistent corneal edema, uveitis, cystoid macular edema, or retinal detachment were not observed. Four patients developed vitreous hemorrhage diagnosed on post-operative day 1 that resolved spontaneously within three weeks in all cases.

Conclusions:: The 25-gauge PPVcombined with the MMIF was found to be a safe, efficient, and visually rewarding technique. The visual rehabilitation seems faster than other methods of managing IOL dislocation. Vitreous Hemorrhage was observed as a specific, but only a transient complication.
