Further study details as provided by Ludwig-Maximilians - University of Munich:

Primary Outcome Measures:
  • 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:
  • 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 ]
