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.

Primary Purpose: Treatment
Myopia
  • Device: Lotrafilcon B contact lens
    Commercially marketed, silicone hydrogel, spherical contact lens having a recommended replacement schedule of monthly.
  • Device: Habitual contact lens
    Habitual soft spherical contact lens having a recommended replacement schedule of 2 weeks or monthly.
  • Lotrafilcon B / Habitual
    Lotrafilcon B contact lenses worn first, with habitual contact lenses worn second. Both products worn bilaterally as often as is typical for habitual lenses, and in the same modality as is typical for habitual lenses, as prescribed by regular eye care practitioner, with extended wear not to exceed 6 nights.
    Interventions:
    • Device: Lotrafilcon B contact lens
    • Device: Habitual contact lens
  • Habitual / Lotrafilcon B
    Habitual contact lenses worn first, with lotrafilcon B lenses worn second. Both products worn bilaterally as often as is typical for habitual lenses, and in the same modality as is typical for habitual lenses, as prescribed by regular eye care practitioner, with extended wear not to exceed 6 nights.
