ObjectiveAcknowledging the rates of endophthalmitis after cataract surgery is very important to understand the seriousness of the disease. Until now, there is no data of this situation in Argentina. The aim of this study was to estimate the incidence of postoperative endophthalmitis after cataract surgery at a tertiary hospital, a medical facility which provides a high degree of subspecialty expertise, in Buenos Aires, Argentina.MethodRetrospective cohort study of adult patients who underwent cataract phacoemulsification surgery between 2006 and 2020 at Hospital Italiano de Buenos Aires, was performed. Patients with endophthalmitis diagnosis within the first 6 weeks after surgery were included. Those who underwent extracapsular surgery or combined surgeries were excluded.ResultsA total of 29 326 cataract surgeries were performed in ten years. The annual incidence of acute postoperative endophthalmitis after cataract surgery was 0.102% (95% CI 0.069-0.146). Thirty cases of endophthalmitis were diagnosed. The main microorganism was Pseudomonas aeruginosa (45.4%). Final visual acuity was higher than 0.3 (LogMAR) in 46.6% of the patients.ConclusionThe incidence of endophthalmitis after cataract surgery in this hospital is within the range reported globally. Knowing the regional incidence contributes to decide if new prophylaxis measures are necessary.
