The incidence of postoperative endophthalmitis after cataract surgery in China: a multicenter investigation of 2006–2011

Aims To estimate the cumulative incidence of postoperative endophthalmitis, identify risk factors and determine clinical outcomes in China. Methods Medical records were reviewed for all patients with acute-onset endophthalmitis after cataract surgery from January 2006 to December 2011 at eight eye centres of tertiary care hospitals in China. Results Sixty-six cases of presumed endophthalmitis occurred after 201 757 cataract surgeries, yielding a cumulative incidence of 0.033% (95% CI 0.025 to 0.041). Logistic regression analysis revealed that the risk of endophthalmitis increased with intraoperative communication with vitreous (multivariate OR 9.96; 95% CI 4.54 to 21.84; p
