Lotrafilcon B / Galyfilcon A
Lotrafilcon B commercially marketed contact lens randomly assigned to one eye, with galyfilcon A commercially marketed contact lens in the fellow eye for contralateral wear. Lenses were worn in a daily wear (DW) modality for approximately 5 days or more per week, at least 10 hours per day, for up to 4 weeks.

As interpreted and recorded by the participant on a questionnaire as a single, retrospective evaluation of 4 weeks of wear. The participant was asked, "How likely would you be to purchase these lenses?" Purchase intent was graded on a 5-point Likert scale: Definitely would purchase, probably would purchase, may or may not purchase, probably would not purchase, definitely would not purchase. The Top-2-box response (definitely would purchase, probably would purchase) was calculated and reported as a percentage of all responses.
