Primary Outcome Measures
NameTimeMethod
Ocular Symptom: Change From Baseline in Patient-Reported Ocular Dryness Score to Day 14, Using Ora Calibra® Ocular Discomfort & 4-Symptom Questionnaire2 weeks

Ocular dryness from the Ora Calibra® Ocular Discomfort \& 4-Symptom Questionnaire was assessed at the subject level in regard to how both eyes felt. The Ora Calibra® Ocular Discomfort \& 4-Symptom Questionnaire was used, which included rating the severity of 5 symptoms: ocular discomfort, burning, dryness, grittiness, and stinging. Each symptom rating ranged from 0 to 5, where 0 = None and 5 = Worst.

Ocular Sign: Change From Baseline in Total Corneal Staining Score to Day 142 weeks

Corneal staining was performed to grade the degree of corneal epithelial cell injury as measured by fluorescence using slit-lamp examination. Ora Calibra® Scale from 0 to 4 with the use of half grade (0.5) increments, where grade 0 = None and 4 = Severe. Regions assessed were the central, superior, inferior, temporal, and nasal. Total corneal staining score was the sum of all five regions. Analyses were for study eye only.

Secondary Outcome Measures
NameTimeMethod
Eye Dryness: Change From Baseline in Patient-Reported Ocular Symptom to Day 14, Using Visual Analog Scale (VAS)2 weeks

Visual analog scale (VAS) was measured by asking subjects to rate each ocular symptom due to ocular dryness by placing a vertical mark on a horizontal line of length 100 mm to indicate the level of discomfort where 0 mm = No Discomfort and 100 mm = Maximal Discomfort. Symptoms assessed were burning/stinging, itching, foreign body sensation, blurred vision, eye dryness, photophobia, and pain.
