Primary Outcome Measures:
  • To evaluate physical effects of Systane and Refresh Tears in subjects to moderate to severe dry eye. [ Time Frame: Baseline to visit 3 (Day 42) ]
    This is a descriptive study in which changes from baseline in Tear Break up Time, corneal staining, and the Ocular Symptoms Questionnaire will be evaluated by treatment group at every visit. The outcome of the IDEEL questionnaire at Visit 3 will be compared to Visit 1 by treatment group; the results of treatment satisfaction questionnaires will be tabulated by treatment at Visit 3.

Enrollment: 78
