What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Patients With Clinical Success at Month 6
Time Frame: Month 6
Percentage of patients with clinical success at month 6. Clinical success is defined as the percentage of patients with corneal sensitivity (the capability of the cornea to respond to stimulation) >= 50 millimeters in all regions of the study eye at month 6 of the Treatment Phase.
Month 6

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Keratocyte Density in the Anterior Flap of the Eyes at Month 6
Time Frame: Baseline, Month 6
Change from baseline in keratocyte (specialized cells in the cornea activated after injury or inflammation) density (thickness) in the anterior flap of the eyes (better eye and worse eye) at month 6 of the Treatment Phase. A positive number change from baseline represents an increase in density (improvement). A negative number change from baseline represents a decrease in density (worsening).
Baseline, Month 6
Change From Baseline in Goblet Cell Density of the Eyes at Month 6
Time Frame: Baseline, Month 6
Change from baseline in goblet cell density of the eyes (better eye and worse eye) at month 6 of the Treatment Phase. Goblet cells are special cells in the eye that support a healthy tear film. A positive number change from baseline represents an increase in goblet cells (improvement).
Baseline, Month 6
