A study with more than 1.5 million cataract surgeries found that endophthalmitis rates lowered with the use of intracameral moxifloxacin prophylaxis.

Intracameral moxifloxacin was found to be a safe and effective prophylactic antibiotic to reduce endophthalmitis rates in both phacoemulsification and manual small-incision cataract surgery patients, according to a study presented by Aravind Haripriya, MBBS, Aravind Eye Hospital, Chennai, India.
The treatment also was shown to be effective in eyes that had posterior capsule rupture, leading Dr. Haripriya and the study’s coauthors to recommend using it in that particular subset of eyes, which are at higher risk for endophthalmitis. Dr. Haripriya cited studies that reported the overall postoperative endophthalmitis rate increases by 7- to 10-fold when posterior capsule rupture occurs.1,2
The study done by Dr. Haripriya and co-researchers was a retrospective review of all cataract surgeries performed from 2012 to 2017 at 10 centers of Aravind Eye Hospital. The use of intracameral moxifloxacin began in August 2014 at one center and then expanded to the other nine centers over the following 6 months.
The intracameral moxifloxacin was ready to use, with no mixing or dilution required. It was available in a 1-ml vial, with each milliliter containing 5 mg of moxifloxacin. The dosing given was 0.5 mg/0.1 ml that was injected in the anterior chamber at the end of surgery.
Standardized operating room and sterilization protocols were used across all Aravind eye hospitals. Patients also received topical ofloxacin at 1 day before surgery and for 15 days after surgery.
“Topical povidone–iodine was used immediately prior to surgery to prep the periorbital area and the conjunctival cul-de-sac,” Dr. Haripriya said.
