Summary

Pars plana vitrectomy effectively removes dislocated lens fragments after cataract surgery, improving visual acuity. This procedure reduces inflammation and speeds visual recovery, with no significant difference between early and delayed interventions.

Area of Science:

Ophthalmology
Retinal Surgery

Background:

Posteriorly dislocated lens fragments are a complication of phacoemulsification during cataract surgery.
Pars plana vitrectomy is a surgical option for managing these fragments.

Purpose of the Study:

To evaluate the clinical features and outcomes of eyes treated with pars plana vitrectomy for posteriorly dislocated lens fragments.

Main Methods:

Retrospective chart review of 126 eyes undergoing pars plana vitrectomy for dislocated lens fragments.
Analysis of clinical features, visual acuity, and postoperative outcomes.

Main Results:

Elevated intraocular pressure (52.4%) and uveitis (69.6%) were common at presentation.
Mean final visual acuity improved significantly to 20/40 (median, 20/50) from 20/278 (median, 20/400).

44% achieved 20/40 or better final visual acuity; posterior chamber IOLs showed better outcomes than anterior chamber IOLs or aphakia.

Conclusions:

Pars plana vitrectomy is effective for removing dislocated lens fragments, reducing inflammation, and improving vision.
No significant difference in outcomes was observed between early (<7 days) and delayed (≥8 days) vitrectomy.
