Purpose
To compare visual acuity outcomes and adverse events in patients with retained lens fragments who underwent same-day versus later pars plana vitrectomy (PPV).Design
Retrospective, interventional case series.
Methods
Single-center study evaluating all patients with retained lens fragments that underwent PPV over a 22-year period (1990 through 2011).
Results
The study included 569 eyes of 568 patients with a mean age of 74.6 years and a median follow-up of 8?months (range, 1?week to 100?months). One hundred seventeen patients (22 % ) underwent same-day vitrectomy, 131 patients (23 % ) underwent PPV within 1?week, and 321 patients (57 % ) underwent PPV more than 1?week later. Median time to vitrectomy in the same week group was 5?days, compared with 22?days in the delayed group. At the last examination, 61 % , 63 % , and 56 % of patients undergoing PPV on the same day, within 1?week, and more than 1?week later, respectively, achieved best-corrected visual acuity (BCVA) of 20/40 or better (<em>Pem>?= .35), and 16 % , 15 % , and 21 % , respectively, had BCVA of 20/200 or worse (<em>Pem>?= .29). There were no differences between groups when assessing cystoid macular edema (<em>Pem>?= .96), retinal detachment (<em>Pem>?= .096), elevated intraocular pressure (<em>Pem>?= .88), or suprachoroidal hemorrhage (<em>Pem>?= .26).
Conclusions
Patients undergoing same-day versus a later PPV (within 1?week or more than 1?week later) for retained lens fragments had similar visual acuity outcomes and complication rates. Although same-day surgery may be attractive logistically in many cases, our retrospective data suggest equivalent outcomes for surgical timing.
