Incidence of acute postoperative endophthalmitis after cataract surgery a nationwide study in France from 2005 to 2014

International audience; PURPOSE:To report the incidence of acute postoperative endophthalmitis (POE) after cataract surgery from 2005 to 2014 in France.DESIGN:Cohort study.PARTICIPANTS:Patients undergoing operation for cataract surgery by phacoemulsification and presenting acute POE.METHODS:We identified acute POE occurring within 6 weeks after phacoemulsification cataract surgery and the use of intracameral antibiotic injection during the surgical procedure by means of billing codes from a national database.MAIN OUTCOME MEASURES:Incidence of acute POE.RESULTS:From January 2005 to December 2014, 6 371 242 eyes in 3 983 525 patients underwent phacoemulsification cataract surgery. The incidence of acute POE after phacoemulsification decreased from 0.145% to 0.053% during this 10-year period; the unadjusted incidence rate ratio (IRR) (95% confidence interval) was 0.37 (0.32-0.42; P < 0.001). In multivariate analysis, intracameral antibiotic injection was associated with a lower risk of acute POE 0.53 (0.50-0.57; P < 0.001), whereas intraoperative posterior capsule rupture, combined surgery, and gender (male) were associated with a higher risk of acute POE: 5.24 (4.11-6.68), 1.77 (1.53-2.05), and 1.48 (1.40-1.56) (P < 0.001), respectively.CONCLUSIONS:Access to a national database allowed us to observe a decrease in acute POE after phacoemulsification cataract surgery from 2005 to 2014. Within the same period, the use of intracameral antibiotics during the surgical procedures increased.
