Primary Outcome Measures
NameTimeMethod
Number of Eyes With No Change in Corneal StainingChange from baseline after 1, 2, 4 and 6+ hours of wear

Subjects examined after corneal staining (a method used to assess the condition of the cornea) using a slit lamp to determine change from baseline and rated based on the following scale: 0=no change from baseline, 1=trace, 2=mild, 3=moderate, 4=severe.
