Ocular Flora and Their Antibiotic Resistance Patterns in the Midwest: A Prospective Study of Patients Undergoing Cataract Surgery

Our cohort harbored organisms with similar rates of antibiotic resistance as elsewhere in the country, including oxacillin resistance; however, the rate of fluoroquinolone resistance was less than in other reports. A surprisingly large proportion of different CNS strains from the same eye harbored different antibiotic susceptibility profiles. Our in vitro results, along with those of other investigators, should prompt further dialogue regarding antibiotic of choice for perioperative surgical prophylaxis in ophthalmic surgery.
