PRIMARY outcome
Timeframe: after 1 week of lens wearPopulation: This analysis includes all participants that completed the study per protocol.
Investigators examined subjects using a slit lamp and the following scale: 0=none, 1=trace, 2=mild, 3=moderate, 4=severe. This outcome measures the number of eyes that had corneal edema graded 2 or higher at the 1-week visit.
