Current Primary Outcome Measures  ICMJE
 (submitted: April 18, 2012)
Average Subjective Comfort [ Time Frame: Insertion, 4 hours, 8 hours each: Day 1, Day 2, and Day 3 ]
Participants were asked, "How would you rate your comfort with your study lenses?" and indicated their response by marking a continuum line ranging from 0=very poor comfort to 100=excellent comfort. Subjective comfort was collected at three time points (insertion, 4 hours, 8 hours) for 3 days, and the comfort ratings were averaged together.
Original Primary Outcome Measures  ICMJE
 (submitted: July 1, 2010)
The primary outcome is subjective comfort. [ Time Frame: 60 days ]
