Primary Outcome Measures:
  • Exploratory Outcomes From Digital Photography [ Time Frame: 24 hours after administration of first dose ]
    Photographs were taken before and after treatment. Outcome is the number of patients whose photographs showed a subjective visual change based upon an exploratory review of patient photographs in signs of bacterial conjunctivitis before and after treatment.

Secondary Outcome Measures:
  • Exploratory Evaluation of Changes in Ocular Signs and Symptoms [ Time Frame: Baseline (Day 1) to Day 2 ]

    Number of patients who had clinical resolution (0 on all scales below) from baseline (Day 1) to Day 2 in ocular and symptoms of bacterial conjunctivitis:

    Bulbar Conjunctival Injection - 0 (none) to 4 (Severe) scale. Conjunctival Discharge (Mucopurulent) - 0 (none) to 3 (Severe) scale. Lid Erythema - 0 (none) to 3 (Severe) scale. Lid Swelling - 0 (none) to 3 (Severe) scale. Palpebral Conjunctiva - 0 (none) to 3 (Severe) scale. Foreign Body Sensation - 0 (none) to 3 (Severe) scale. Tearing - 0 (none) to 3 (Severe) scale. Photophobia - 0 (none) to 3 (Severe) scale.

  • Microbiological Culture Evaluation/Eradication Percent - Enterobacter Faecalis and Candida Albicans [ Time Frame: 24 hours after administration of first dose ]
    Eradication percent (absence of specified bacteria) of each bacteria identified at Day 1

  • Microbiological Culture Evaluation/Eradication Percent - Eradication of All Other Isolates and Corynform-like [ Time Frame: 24 hour after administration of first dose ]
    Eradication percent (absence of specified bacteria) of each bacteria identified at Day 1

  • Microbiological Culture Evaluation/Eradication Percent - Staphylococcus Aureus, Steptococcus Pneumoniae, and Enterobacter Cloacae [ Time Frame: 24 hours after administration of first dose ]
    Eradication percent (absence of specified bacteria) of each bacteria identified at Day 1

  2. Any current lid disease on clinical examination.
  3. Known or suspected allergy or hypersensitivity to fluoroquinolones.
  4. Suspected fungal, viral (e.g. Herpes simplex) or Acanthamoeba infection, based on clinical observation.
  5. Any systemic or ocular disease or disorder, complicating factors or structural abnormality that would negatively affect the conduct or outcome of the study (e.g., hepatitis, acute or chronic renal insufficiency).
  6. Use of topical ocular medications during the study period.
  7. Antibiotics (systemic or topical) may not be used within 7 day of visit 1 or anytime after this visit for the duration of the study.
  8. Women of childbearing potential not using reliable means of birth control.
  9. Women who are pregnant or lactating.
