Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Symptom Assessment in Dry Eye (SANDE) Questionnaire	Mean change from baseline in total SANDE score at Visit 7/Day 84; The SANDE questionnaire contained two questions regarding the frequency and severity of DED symptoms, with a total score being the square root of the frequency score times the square root of the severity score (range 0 100). A higher score indicates more severe DED symptoms.	84 days
Secondary	Tear Breakup Time	Mean change from baseline at each visit	84 days
Secondary	Anesthetized Schirmer's Test	Mean change from baseline at Visit7/Day 84	84 days
Secondary	Conjunctival Hyperemia	Mean change from baseline at each visit.; Reported on a scale of 0-15 with values greater than 3 indicating abnormal incidence of conjunctival surface irregularity.	84 days
Secondary	Corneal Fluoroscein Staining	Mean change from baseline at each visit; Reported on a scale of 0-15 with values greater than 3 indicating abnormal incidence of corneal surface irregularity.	84 days
