Purpose: To identify risk factors for intraoperative vitreous complications in resident-performed phacoemulsification surgery

Setting: Two urban public county hospitals

Design: Case series

Methods: Phacoemulsification cataract surgeries performed by residents between January 4, 2005, and January 8, 2008, were retrospectively reviewed. Clinical characteristics of patients with and without intraoperative vitreous complications were compared and independent factors associated with vitreous complications identified using univariate and multivariate analysis.

Results: Of 2,434 cases meeting inclusion criteria, there were 92 vitreous complications (3.8%). On univariate analysis, significant pre-operative risk factors for vitreous complications included older age (P=.020), poor pre-operative corrected distance visual acuity (CDVA) (P=.007), left eye (P=.043), history of trauma (P=.045), prior pars plana vitrectomy (P=.034), dementia (P=.020), phacodonesis (P=.014), zonule dehiscence (P<.0001), posterior polar cataract (P=.037), white/mature cataract (P=.005), dense nuclear sclerotic cataract (P=.0006), and poor red reflex (P=.002). Factors that remained significant on multivariate analysis were older age (odds ratio [OR], 1.03; 95% confidence interval [CI], 1.01-1.05), poor pre-operative CDVA (OR, 1.52; 95% CI, 1.14-2.03), left eye (OR, 1.63; 95% CI, 1.05-2.51), prior pars plana vitrectomy (OR, 1.88; 95% CI, 1.01-3.51), dementia (OR, 3.65; 95% CI, 1.20-11.17), and zonule dehiscence (OR, 8.55; 95% CI, 3.92-18.63).

Conclusion: Elements of the pre-operative history and examination can identify patients at higher risk for intraoperative complications during resident-performed phacoemulsification surgery.
