Purpose • To evaluate visual outcomes and complications in patients with immediate pars plana vitrectomy for posteriorly dislocated intravitreal lens fragments during phacoemulsification

Methods • Patients with posteriorly dislocated intravitreal lens fragments during phacoemulsification • Underwent immediate pars planavitrectomy by a vitreoretinal surgeon • As part of the routine management strategy in a tertiary eye center. • A retrospective review of all consecutive cases from 2001 to 2006 was performed. • Data collected included demographics, best corrected visual acuity (BCVA) and complications including retinal detachment, raised intraocular pressure (IOP) and cystoid macular edema (CME).

Results Demographics • 45 eyes of 46795 cases of phacoemulsification were included in the study • Median age of patients: 69 years • Median follow-up : 11 months after vitrectomy.

Best Corrected Visual Acuity

Patients with BCVA 20/40 or better

Conclusion • The majority of cases of posteriorly dislocated intravitreal lens fragments had good visual outcome. Immediate pars plana vitrectomy has minimal sight-threatening complications and is a good management strategy to adopt in a tertiary setting.
