Outcome Measures
Primary Outcomes (10)
Corneal Epithelial Immune Dendritic Cell Density (Central Cornea)
The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.
Six weeks
Corneal Epithelial Immune Dendritic Cell Density (Inferior Cornea)
The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.
Six weeks
Corneal Epithelial Immune Dendritic Cell Density (Nasal Cornea)
The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.
Six weeks
Corneal Epithelial Immune Dendritic Cell Density (Superior Cornea)
The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.
Six weeks
Corneal Epithelial Immune Dendritic Cell Density (Temporal Cornea)
The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.
Six weeks
Corneal Epithelial Immune Non-Dendritic Cell Density (Central Cornea)
The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.
