Effectiveness of Topical 0.5% Levofloxacin to Reduce the Conjunctival Bacterial Flora Before Intraocular Surgery

Summary

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.
