Sponsors and Collaborators:	Ludwig-Maximilians - University of Munich Santen Gmbh
Information provided by:	Ludwig-Maximilians - University of Munich
ClinicalTrials.gov Identifier:	NCT00491049

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.

Condition	Intervention	Phase
Conjunctival Bacterial Flora	Drug: 0.5% levofloxacin eye drops	Phase IV

Drug Information available for: Tetrahydrozoline Tetrahydrozoline hydrochloride Levofloxacin Ofloxacin Ofloxacin hydrochloride

U.S. FDA Resources

Study Type:	Interventional
Study Design:	Prevention, Randomized, Double-Blind, Active Control, Parallel Assignment, Safety/Efficacy Study
Official Title:	Phase 4 Study on Effectiveness of Topical 0.5% Levofloxacin on Reduction of Preoperative Conjunctival Flora in Patients Scheduled for Intraocular Surgery

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 ]

Enrollment:	140
