Primary Outcome Measures:
  • The primary efficacy endpoint for this study is the change from baseline to Day 15 in the signs and symptoms composite score [ Time Frame: 15 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The distribution of Investigator global assessment at each visit. [ Time Frame: Visit 2, 3 & 4 ] [ Designated as safety issue: No ]
  • The percentage of eyes that were considered improved or cured at each visit based on the Investigator global assessment. [ Time Frame: Visit 2, 3 & 4 ] [ Designated as safety issue: No ]
  • The change from baseline to Day 7 (Visit 3) and to Day 3 (Visit 2) in the signs and symptoms composite score. [ Time Frame: Visit 2 & 3 ] [ Designated as safety issue: No ]
  • The change from baseline to each visit in the signs composite score and the symptoms composite score. [ Time Frame: Visit 1, 2, 3 & 4 ] [ Designated as safety issue: No ]
  • The change from baseline to each visit in the Blepharitis signs composite score, the conjunctivitis signs composite score, and the Keratitis signs composite score. [ Time Frame: Visit 1, 2, 3 & 4 ] [ Designated as safety issue: No ]
  • The change from baseline to each visit in individual signs and symptoms. [ Time Frame: Visit 1, 2, 3 & 4 ] [ Designated as safety issue: No ]
  • VA, Biomicroscopy, and IOP assessments at each visit [ Time Frame: Visit 1, 2, 3 & 4 ] [ Designated as safety issue: No ]
  • Adverse Events [ Time Frame: Visit 1, 2, 3 & 4 ] [ Designated as safety issue: No ]
