Outcome Measures

Primary Outcomes (1)

  • Visual Analog Scale (VAS) Global Ocular Discomfort Score, Area Under the Curve, Day 0 to Day 28

    An electronic Visual Analog Scale (eVAS) was used by the subject to assess ocular discomfort, both frequency and severity, at Day 0 (pre-treatment) and daily thereafter for 28 days. Assessments were entered into a LogPad® (handheld electronic device). The VAS frequency score ranged from 0 (rarely) to 100 (all the time), and the VAS severity score ranged from 0 (very mildly uncomfortable) to 100 (very severely uncomfortable). The Global Ocular Discomfort Score is a composite of the frequency and severity VAS scores (0-100).

    Up to 28 days
