- Primary Outcome Measures
Name Time Method Corneal Staining by Wear Time 1 hour on Day 1, 2 hours on Day 2, 4 hours on Day 3 and End of Day on Day 4 All participants were contact lenses wearers and were evaluated with a Corneal Staining at 1 hour, 2 hours, 4 hours and end of day. The corneal staining test is performed using fluorescein drops in the eye and ultraviolet illumination to determine if there has been any damage to the cornea from the use of the lens solutions or from the use of the contact lens.
- Secondary Outcome Measures
Name Time Method Subjective Solution Preference Day 4 All subjects were asked which solution they prefer based on comfort level: Biotrue MPS, Investigational MPS, or no difference.
Overall Ocular Comfort Day 4 All subjects were asked to rate their lens comfort at each visit based on an 11 point scale where 0 meant that the lens could not be tolerated and 10 indicated that the lens could not be felt.
