[Management of posteriorly dislocated lens material after complicated phacoemulsification. The vitreoretinal surgeon's point of view].

Posterior dislocation of lens material is a serious complication of phacoemulsification. Its prognosis depends on timely treatment, well-planned by cataract and vitreoretinal surgeons working in collaboration. Pars plana vitrectomy with removal of the dislocated material is nearly always mandatory on a short-term basis in order to prevent and/or treat any further complication, mainly uveitis, hypertony, corneal edema, cystoid macular edema, and retinal detachment. The best time to implant and perform pars plana vitrectomy is still a matter of controversy. The best predictor of final visual acuity is the visual acuity before vitrectomy.
