Abstract: Objective To identify the risk factors for rupture of the posterior capsule during phacoemulsification cataract surgery. Methods The clinical data for patients who underwent phacoemulsification cataract surgery at our hospital between January 1, 2014 and December 31, 2016 were retrospectively reviewed. The data for 42 eyes(38 patients)in which posterior capsule rupture occurred intraoperatively were compared to those for 215 randomly selected eyes(190 patients)in which posterior capsule rupture did not occur(ratio 1∶5). Univariate and multivariate logistic regression models were used to identify risk factors for posterior capsule rupture during phacoemulsification cataract surgery. Results Univariate analysis revealed that patient sex, preoperative visual acuity <20/200, surgery for retinal detachment, vitreous surgery, vitreous hemorrhage, and nuclear stage were associated with rupture of the posterior capsule during phacoemulsification cataract surgery. In multivariate analysis, preoperative visual acuity <20/200, vitreous hemorrhage, and degree of nuclear sclerosis remained as independent risk factors for posterior capsule rupture in phacoemulsification cataract surgery. Conclusion Posterior capsular rupture is more likely to occur during phacoemulsification cataract surgery in patients with a preoperative visual acuity <20/200, vitreous hemorrhage, and a higher degree of nuclear sclerosis.
