Complications and patient factors contributing to outcomes were assessed using paired and unpaired t-tests and multiple linear regression.Results: 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).Conclusions/Relevance: 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.Keywords: trainee, complicated cataract surgery, retained lens fragments, resident, fellow, pars plana lensectomy, pars plana vitrectomy, teaching, surgical educationLin WVScott MNTendhar CAli SFAl-Mohtaseb ZShaikh RWeng CYDove Medical Pressarticletraineecomplicated cataract surgeryretained lens fragmentsresidentfellowpars plana lensectomypars plana vitrectomyteachingsurgical educationOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 939-946 (2020)
