Titre	Clinical Features and Outcomes of Pars Plana Vitrectomy for posteriorly dislocated lens fragments in phakoemulsification
Abstract Nr.	A2038

But	To investigate the clinical features, visual acuity outcomes, and adverse events in patients with retained lens fragments managed by pars plana vitrectomy (PPV).
Méthodes	We carried out a retrospective review of all patients who undergoing PPV for retained lens fragments at our institution between June 1997, and December 2002.
Résultats	The study included 52 eyes of 52 patients, with a median age of 74,5 years and a median follow-up after PPV of 16,6 months. The median interval between cataract surgery and PPV was 7 days. Among the 43 aphakic eyes, a posterior chamber intraocular lens was placed at the time of PPV in 36 eyes and an anterior chamber intraocular lens was placed in 2 eyes; 5 eyes remained aphakic. Visual acuity was >= 20/40 in 27 (52%) patients and <= 20/200 in 12 (23%) patients at last follow-up. Among the 25 patients with final vision < 20/40, the primary cause of visual impairment was glaucoma (6/25), history of retinal detachment (5/25), cystoid macular edema (4/25), preexisting ocular disease (3/25), corneal edema (1/25), and other causes (6/25). Timing of PPV was not significantly associated with better final visual acuity. Presence of an intraocular lens before PPV was associated with better final visual acuity but did not reach a statistical significant level (P = 0,09).
Conclusion	Dislocation of the nucleus into the vitreous during phakoemulsification is a serious complication of modern cataract surgery. Management requires secondary vitrectomy and lens implantation can be carried out in most of the cases during the same procedure.
