Abstract
Purpose
To report the results of managing dislocated posterior chamber intraocular lenses (PC IOLs) by externalizing both haptics alternately through a single clear corneal incision.
Methods
The study included 10 eyes of 10 patients in which a dislocated PC IOL was managed with pars plana vitrectomy. With our modified method, both haptics were alternately externalized through a single clear corneal incision for suture knot placement and then reinserted.
Results
The dislocated PC IOLs were repositioned successfully in all 10 eyes, and the corrected visual acuity improved postoperatively in 9 eyes at a minimum follow-up of six months. Abnormal IOL position, IOL capture by the iris, or posterior synechia was not observed. Hypotony maculopathy occurred in one eye, but the macular folding disappeared and the visual acuity improved after adding one-bite suture.

Figure 1.
(A) The PC IOL is placed in the anterior chamber through the pupil and over the iris. And a 10-0 Prolene is placed posterior to the iris through a sclerotomy under the scleral flap. Middle portion of the 10-0 Prolene is pulled out through a clear corneal incision. (B) One haptic is externalized through a clear corneal incision under direct visualization, and tied with the divided end of 10-0 Prolene. (C) The PC IOL is rotated in the anterior chamber and the other haptic is externalized through a clear corneal incision, and tied with the other end of 10–0 Prolene. (D) The PC IOL is reimplanted and the sutures attached to each haptic are pulled through the fixation sclerotomy under the scleral flap.
