Primary Outcome Measures :
  1. Rate of culture positive results in thioglycolate broth from conjunctival swabs at defined time points [ Time Frame: maximum 7 days before surgery until conclusion of surgery ]

Secondary Outcome Measures :
  1. Numbers of colony forming units (CFUs) found on solid media. Specimens were cultured aerobically and micro-aerobically on blood agar plates and anaerobically on chocolate agar plates and CFUs were determined on each plate using a magnifying glass. [ Time Frame: maximum 7 days before surgery until concluison of surgery ]
