Primary Outcome Measures:
  • Change From Baseline in Subjective Evaluation of Symptom of Dryness (SESoD)Score at Day 90 [ Time Frame: Baseline (Day 1), Day 90 ] [ Designated as safety issue: No ]
    Change from baseline in SESoD score at day 90. The SESoD is a 5-point scale where 0 equals no dryness, 1 equals trace dryness, 2 equals mild dryness, 3 equals moderate dryness, and 4 equals severe dryness. A negative number change from baseline indicates a decrease (improvement) in the symptom of dryness.


Secondary Outcome Measures:
  • Change From Baseline in the Ocular Surface Disease Index (OSDI) Total Score at Day 90 [ Time Frame: Baseline (Day 1), Day 90 ] [ Designated as safety issue: No ]
    Change from baseline in the OSDI total score at day 90. The OSDI is a 12-question survey for patients to document their dry eye disease symptoms. The OSDI consists of a 5-point scale (0=none of the time and 4=all of the time), with higher scores representing greater disability. The scores are totaled over the 12 questions and converted to a score of 0-100 (0=no disability and 100=complete disability). A negative number change from baseline represents an improvement.

  • Change From Baseline in Tear Break-up Time (TBUT) at Day 90 [ Time Frame: Baseline (Day 1), Day 90 ] [ Designated as safety issue: No ]
    Change from baseline in TBUT at day 90. TBUT is the time required for dry spots to appear on the surface of the eye after blinking. The longer it takes, the more stable the tear film. A short TBUT is a sign of poor tear film. A positive number change from baseline indicates an increase in TBUT (improvement).

  • Change From Baseline in Corneal Staining at Day 90 [ Time Frame: Baseline (Day 1), Day 90 ] [ Designated as safety issue: No ]
    Change from baseline in corneal staining at day 90. The cornea is the transparent front part of the eye which covers the iris and pupil. Corneal staining following administration of fluorescein dye in the eye is graded using a 6-point scale (0=no staining, 5=severe staining) over 5 areas of the clear central part of the eye for a minimum score of 0 and maximum score of 25. The higher the grade score, the worse the dry eye condition. A negative number change from baseline represents a decrease in corneal staining (improvement).

  • Change From Baseline in Conjunctival Staining Severity Score at Day 90 [ Time Frame: Baseline (Day 1), Day 90 ] [ Designated as safety issue: No ]
    Change from baseline in conjunctival staining severity score at day 90. The conjunctiva is the clear membrane covering the white surface of the eye. Conjunctival staining following ocular administration of lissamine green dye was graded using a 6-point scale (0=no staining, 5=severe staining) over 6 areas of the white part of the eye for a minimum score of 0 and a maximum score of 30. The higher the score, the worse the dry eye condition. A negative number change from baseline represents a decrease in the severity of conjunctival staining (improvement).
