Primary Outcome Measures:
  • On-eye Wettability [ Time Frame: 4 weeks of wear ] [ Designated as safety issue: No ]
    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.

Arms Assigned Interventions
Active Comparator: lotrafilcon B
Lotrafilcon 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.
Device: lotrafilcon B
Commercially marketed, silicone hydrogel, spherical contact lens
Other Name: Air Optix
Active Comparator: balafilcon A
Balafilcon 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.
Device: balafilcon A
Commercially marketed, silicone hydrogel, spherical contact lens
Other Name: PureVision
Active Comparator: senofilcon A
Senofilcon A contact lens randomly assigned to one eye, with enfilcon 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 lotrafilcon B contact lens randomly assigned to one eye and balafilcon A contact lens in the fellow eye for an additional 4 weeks of daily wear.
Device: senofilcon A
Commercially marketed, silicone hydrogel, spherical contact lens
Other Name: Acuvue OASYS
Active Comparator: enfilcon A
Enfilcon A contact lens randomly assigned to one eye, with senofilcon 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 lotrafilcon B contact lens randomly assigned to one eye and balafilcon A contact lens in the fellow eye for an additional 4 weeks of daily wear.
