Arm Intervention/treatment
Experimental: Lotrafilcon A
Investigational contact lens worn in both eyes for three months
Device: Lotrafilcon A contact lens
Investigational silicone hydrogel, single vision, soft contact lens worn on a daily wear basis, flexible wear basis, or extended wear basis for three months

Primary Outcome Measures :
  1. Comfort After Insertion [ Time Frame: 3 months ]
    Comfort after insertion (30 seconds to 1 minute) as interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of three months' wear time. Comfort after insertion was measured on a 10-point scale, with 1 being poor and 10 being excellent.
