Pars plana vitrectomy in the management of dislocated posterior chamber lenses.
We used pars plana vitrectomy techniques in the management of pseudophakia and a dislocated posterior chamber lens in 17 patients. In six patients, the implant was decentered with the optic axis still located in the visual axis. In nine patients, the implant was rotated inferiorly and posteriorly but with the haptic still adherent to the vitreous base. In two patients, the implant was dislocated into the vitreous cavity. Surgical repositioning of the implant was indicated in 12 (71%) patients because of retained lens material, vitritis, vitreous adhesion to the cataract wound, vitreous hemorrhage, or retinal detachment. Preoperatively, visual acuity ranged from 20/30 to hand motions. Postoperatively, visual acuity ranged from 20/20 to 20/400. In eight patients, visual acuity was improved to 20/25 or better.
