Background: Endophthalmitis is a serious infectious complication of cataract surgery, which may lead to vision loss. Aim: To evaluate the effectiveness of intracameral moxifloxacin in reducing endophthalmitis after cataract surgery in Chilean patients. Material and Methods: We reviewed all phacoemulsification surgeries performed between 2012 and 2020 at a public hospital. The use of intraoperative intracameral moxifloxacin and possible surgical complications were recorded. In patients with postoperative endophthalmitis, we reviewed their risk factors and clinical characteristics. Results: In the study, 22,869 phacoemulsification surgeries were registered, with an annual average of 2,541. The use of prophylactic intracameral moxifloxacin started progressively in 2014. In 2018 it was used in 88% of the surgeries. Fifteen eyes evolved with postoperative endophthalmitis, but none of these surgeries used intracameral moxifloxacin. Five and seven cases occurred in 2012 and 2013, respectively. There was a trend favoring moxifloxacin use, as a preventive measure for endophthalmitis, but the difference between groups was not significant (p = 0.56). In the group with endophthalmitis, 33.3% of the eyes were from patients with type 2 diabetes mellitus, in 13.3% there was rupture of the posterior capsule and 60% of the eyes corresponded to female patients. Since 2018 there is no record of endophthalmitis after cataract surgery performed in this center. Conclusions: Intracameral moxifloxacin showed a tendency to reduce the frequency of endophthalmitis after phacoemulsification surgery, but a longer observation period is required to reach statistical significance, due to the low frequency of this complication.
