SECONDARY outcome

Timeframe: 4 weeks

Population: analysis was per protocol

Grading based on Type (0=None; 100=patch)and extent of staining (0=None; 100= Entire corneal region). Final value is Type multiplied by Extent. Corneal staining is a test that uses an orange dye (fluorescein) and a blue light to detect damage to the cornea (front surface of eye) from minor abrasions. A strip of blotting paper containing the dye was touched to the eyelid margin. Upon blinking, the dye spreads and coats the front surface of the eye along with the tear film covering the surface of the cornea. The investigator then rated the size, location and shape of the staining.
