Brief Summary:
The purpose of the present study is to elucidate the spectrum of ocular flora and their antimicrobial susceptibility profiles in patients undergoing routine cataract surgery.

Condition or disease
Disorders of the Eye Following Cataract Surgery

Detailed Description:
A conjunctival and palpebral swab will executed at least 14 days before routine cataract surgery. Isolates will be identified using standard microbiological protocols. In vitro susceptibility will be determined using a breakpoint minimal inhibitory concentrations. In case of positivity, the swab will be repeated the day of surgery. Topical antibiotic may be used in case of positivity at the discretion of the surgeon. Descriptive statistics will be calculated.

Study Type : Observational

Primary Outcome Measures :
  1. Positive Culture in Subjects Scheduled for Cataract Surgery [ Time Frame: At least 14 days before surgery ]
    Number of participants with positive culture at the screening visit

Secondary Outcome Measures :
  1. Antibiotic Susceptibility [ Time Frame: At least 14 days before surgery ]
    Isolated bacteria were tested for their in vitro susceptibility to commercially available ophthalmic antibiotics by the disk diffusion test and categorized as susceptible, intermediate or resistant.

  2. Eradication Rate [ Time Frame: Day of surgery ]
    Number of participants having positive culture at the screening visit with bacterial eradication before surgery
