Comfort Upon Insertion
Time Frame: 4 weeks of wear
|
Comfort upon insertion, as interpreted by the participant, was recorded on a questionnaire by the participant using a 10-point scale, with 1 being poor and 10 being excellent.
Comfort upon insertion was assessed as a single, retrospective evaluation of 4-weeks' wear time.
