Primary Outcome Measures :
  1. Subjective Rating of Overall Comfort [ Time Frame: Up to Day 28 ]
    Overall comfort, as rated by the participant on a 10-point scale, with 1 being poor and 10 being excellent. The participant rated both eyes together by providing one single rating.


Secondary Outcome Measures :
  1. Subjective Rating of Overall Vision [ Time Frame: Up to Day 28 ]
    Overall vision, as rated by the participant on a 10-point scale, with 1 being poor and 10 being excellent. The participant rated both eyes together by providing one single rating.

  2. Proportion of Subjects Preferring Study Lens (Strongly or Somewhat) [ Time Frame: Day 28 ]
    Participants were asked to compare the study lenses to their habitual lenses using a 5-point scale: strongly prefer study lenses, somewhat prefer study lenses, no preference, somewhat prefer habitual lenses, and strongly prefer habitual lenses, where 'study lenses' refer to either test or control depending on the treatment group. Proportion of subjects preferring study lens is reported as the percentage of participants who strongly or somewhat preferred the study lens.

  • History of at least 5 days of successful use with both lenses (minimum of 8 hours/day) of one of the protocol-specified lens care solutions/multi-purpose solutions (MPS).
  • Other protocol-specified inclusion criteria may apply.

Exclusion Criteria:

  • Any ocular or systemic medical condition that may, in the opinion of the investigator, preclude safe administration of the test articles or affect the results of this study.

  • Monovision, monocular (only one eye with functional vision) or fit with only one lens.
  • History of intolerance or hypersensitivity to any component of the test articles.
  • Use of any over-the-counter or prescribed topical ocular medications within the previous 7 days (excluding rewetting drops).
  • Moderate or severe corneal edema, corneal vascularization, corneal staining, injection, tarsal abnormalities, "other" complications; and any corneal infiltrates.
  • Current or history of ocular infection, severe inflammation, or disease within previous 6 months.
  • Any systemic disease (including allergies, respiratory infections or colds) that may affect the eye or be exacerbated by use of contact lenses or contact lens solutions.
  • Participation in any investigational clinical study within previous 30 days.
  • Other protocol-defined exclusion criteria may apply.
