Summary: | To analyze outcomes and complications related to cataract surgery complicated by retained lens fragment (RLF) requiring pars plana vitrectomy (PPV) in a county hospital where procedures are performed by trainees.
Retrospective study of consecutive patients who met inclusion criteria and underwent PPV for RLF in the vitreous cavity at an urban teaching hospital between January 2010 and January 2016 (N=20).
Visual acuity was recorded pre- and post-operatively over a follow-up period of 3 to 12 months. Complications and patient factors contributing to outcomes were assessed using paired and unpaired t-tests and multiple linear regression.
The average rate of cataract surgery with RLF requiring PPV was 0.75%. Twenty patients met inclusion criteria. Mean pre-operative visual acuity (VA) was logMAR 1.7 (Snellen 20/1000). Nearly half (8/20) had nuclear cataracts grade 3+ or higher. The majority (14/20) had factors predisposing them to cataract surgery complications. Most patients underwent PPV within 1 week (median 6.5 days). At 12-month follow-up, significant (p=0.001) visual acuity (VA) improvement from initial VA was observed, with final mean logMAR 0.6 (± 0.75; Snellen 20/80) and median logMAR 0.35 (Snellen 20/45). Nearly half of the patients had a final Snellen VA ≥20/40. Factors associated with less VA improvement were older age and greater proportion of lens dropped (p<0.01). Complications following PPV included hypotony (5 patients), corneal edema (4), elevated intraocular pressure (IOP) (3), and cystoid macular edema (3).
Despite patients with advanced pathology and trainee surgeons, rates of cataract surgery-associated RLF requiring PPV at a large tertiary care teaching hospital are similar to reported rates in the literature. |
