Pars plana vitrectomy with posterior iris claw implantation for posteriorly dislocated nucleus and intraocular lens.

ABSTRACT

We evaluated the safety and efficacy of pars plana vitrectomy (PPV) with primary posterior iris claw intraocular lens (IOL) implantation in cases of posterior dislocation of nucleus and IOL without capsular support. This was a retrospective interventional case series. Fifteen eyes underwent PPV with primary posterior iris claw IOL implantation performed by a single vitreoretinal surgeon. The main outcome measures were changes in best corrected visual acuity and anterior and posterior segment complications. A total of 15 eyes were included in this study. Eight had nucleus drop, three had IOL drop during cataract surgery and four had traumatic posterior dislocation of lens. The final postoperative best corrected visual acuity was 20/60 or better in 11 patients. This procedure is a viable option in achieving good functional visual acuity in eyes without capsular support.
