摘要
PURPOSE: To describe the posterior capsule rupture rates and visual outcomes after phacoemulsification, analyze risk factors for poor vision, and compare results of faculty (F) and residents (R). DESIGN: Retrospective audit study. METHODS: Visual success of all capsule ruptures (2006-2010) was analyzed and compared to uneventful cases. Rupture rates of faculty and residents were compared (chi(2), P < .05). Success was defined as % best-corrected visual acuity (BCVA) >= 20/40 at 3 months (excluding poor-prognosis eyes) and studied in relation to age, sex, surgeon type, stage of surgery, vitreous loss, dropped nucleus, and other complications (eg, retinal detachment, corneal decompensation, dislocated intraocular lens [IOU. Final risk factors were identified using multivariate logistic regression analysis. RESULTS: From 2006 to 2010, there were 887 capsule ruptures in 48377 phacoemulsification cases (rate 1.8%). Uneventful cases had significantly better visual outcomes than capsule ruptures (98.5% vs 93.9%; P < .01). Faculty rupture rates were lower (F = 1.4%) than residents' (R = 3.4%; P < .01), but visual outcomes were similar (F = 93.8%, R = 93.7%; P > .05). Ruptures most frequently occurred during phacoemulsification (59.6%) and irrigation and aspiration (24.8%) stages. Risk factors for poor outcomes included age >65 years, dropped nuclei, and other complications. " CONCLUSION: The overall capsule rupture rate was 1.8%. Although residents had higher rates, visual success matched faculty's, possibly attributable to case mix and close supervision. Associated risk factors for poor vision included age >65 years, dropped nuclei, and postoperative retinal, corneal, and IOL complications.
