What researchers measure

Primary outcomes

  1. Change From Baseline in the Ocular Surface Disease Index© (OSDI©) Score

    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.

    Time frame: Baseline, Day 30

Secondary outcomes

  1. Change From Baseline in the OSDI© Score

    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.

    Time frame: Baseline, Day 7

  2. Change From Baseline in Tear Break-up Time (TBUT)

    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). The eye with shorter average TBUT at baseline is reported for each patient.

    Time frame: Baseline, Day 30

  3. Change From Baseline in the Combined Corneal and Conjunctival Staining Scores

    The cornea is the transparent front part of the eye which covers the iris and pupil. The conjunctiva is the clear membrane covering the white surface of the eye. The cornea is divided into 5 zones and the nasal and temporal conjunctiva is divided into 6 zones. The combined staining score is based on the sum of the five zones on the cornea and the six zones on the conjunctiva. Each zone is graded on a 0-5 scale (0=None; 1=trace; 2=mild; 3=moderate; 4=severe; 5=very severe), for a total score ranging from 0-55. The higher the score, the worse the dry eye condition. A negative number change from baseline represents a decrease in the severity of staining (improvement). The eye with higher score at baseline is reported for each subject.

    Time frame: Baseline, Day 30

  4. Change From Baseline in the Schirmer Test

    The Schirmer's Test measures the rate of the secretion of tears produced by the eye over 5 minutes. The results indicate the presence of dry eye. The eye with the lower value at Baseline was used for Analysis. Normal = greater than or equal to 15 millimeters (mm) of tears, Dry Eye = less than 15 mm of tears.. The smaller the number, the more severe the dry eye. A positive number change from Baseline indicates improvement. The eye with the lower value at baseline is used for each subject.
