Outcome Measures
Primary Outcomes (1)
On-eye Wettability
On-eye wettability, as assessed at the 4-week visit by a masked observer from a video taken of the eye 5 minutes after lens insertion. On-eye wettability was recorded on a 5-point scale, with 0=excellent and 4=very poor.
4 weeks of wear
Study Arms (4)
lotrafilcon B
ACTIVE COMPARATORLotrafilcon B contact lens randomly assigned to one eye, with balafilcon A contact lens assigned to the fellow eye for contralateral wear. Both products to be worn on a daily wear basis for 4 weeks, after which participant will wear senofilcon A contact lens randomly assigned to one eye and enfilcon A contact lens in the fellow eye for an additional 4 weeks of daily wear.
balafilcon A
ACTIVE COMPARATORBalafilcon A contact lens randomly assigned to one eye, with lotrafilcon B contact lens assigned to the fellow eye for contralateral wear. Both products to be worn on a daily wear basis for 4 weeks, after which participant will wear senofilcon A contact lens randomly assigned to one eye and enfilcon A contact lens in the fellow eye for an additional 4 weeks of daily wear.
