Prophylactic intracameral cefazolin after cataract surgery

A 2.5 mg/0.1 mL intracameral bolus of cefazolin provided excellent prophylactic effectiveness, with a reduction in the incidence of endophthalmitis from 0.422% to 0.047%, corresponding to a relative risk reduction of 88.7% (95% CI, 72.6%-95.4%). Cefazolin fulfills international recommendations on antimicrobial prophylaxis for surgical site infections and is easier to obtain in developing countries.
