SECONDARY outcome

Timeframe: 2 weeks

Population: Only the participants who completed the study per protocol (n=78)

Measured for 5 zones of the cornea (superior, nasal, central, inferior, temporal)on a 0 to 3 grade scale (NEI 0-3 scale). Grade 0 = Normal/ grade 1 = mild, superficial stippling/ grade 2 = moderate, punctate staining including superficial abrasion of the cornea/ grade 3 = severe, abrasion or corneal erosion, deep corneal abrasion or recurrent erosion.
