Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in Corneal Staining Scores for Study Eye From Baseline at Week 8
Time Frame: Baseline, Week 8

Based on the National Eye Institute (NEI) dry eye clinical trials workshop, the cornea was divided into 5 different zones. Each corneal zone was graded independently using a 0 to 3 grading scale:0=none, 1=slight, 2=moderate, 3=severe. Sum of scores of each zone led to total score. Total score range: 0 to 15, higher score indicated greater staining. Results from study eye are reported. The study eye was defined as the eye with the worse (higher) corneal staining score at baseline.

Change: score at observation minus score at baseline. Negative change from baseline indicated improvement.
