Purpose

The purpose of this study is to determine whether additional topical application of 0.5% levofloxacin is more effective in reducing the load of the conjunctival bacterial flora in patients scheduled for intraocular surgery than preoperative irrigation of the conjunctiva with povidone iodine alone.

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 ]
