Objective. The purpose of the study is an assessment of the clinical and cost-effectiveness of perioperative antibiotic prophylaxis systemic fluoroquinolones cataract. Methods. It was conducted a retrospective randomized study of the incidence of postoperative infectious complications that developed after the 9314 cataract surgery carried out by ‹small sections’ technology from 2012 to 2014. Patients of the 1st group received 0.5 % levofloxacin instillation (4 times a day for three days before surgery), patients of the 2nd group received additional systemic levofloxacin (orally, 500 mg/day). We calculated relative risk (RR), relative risk reduction (RRR) and absolute risk reduction (ARR) of complications, and the number of patients needed to treat (NNT). Results. In the group of patients receiving antibiotic prophylaxis just as instillation fluoroquinolones , infection rates were 0.25 %, while in the group where the patients received additional systemic fluoroquinolone – 0.02 %. RR was 0.08, RRR – 0.92, ARR – 0.23 %, NNT was 422.8. Systemic antibiotic prophylaxis costs exceed the costs for local antibiotic prophylaxis 1.8 times. At the same time the costs of treatment which developed 12 endophthalmitis in the 1st group exceeded the cost of the system and antibiotic treatment of endophthalmitis after systemic use of levofloxacin. Conclusions. System use of fluoroquinolones in the perioperative period of cataract surgery is an effective method of preventing infectious postoperative complications, both in clinical and economic aspects.
