Primary Outcome Measures:
  • Solution-Related Corneal Staining [ Time Frame: Day 7 ]
    Corneal staining was assessed by the investigator using fluorescein dye, a yellow filter, and a slit lamp. Corneal staining was graded on a continuous scale of 0% (no staining in the region) to 100% (staining covers entire region) in 1% increments for 5 corneal regions (central, nasal, temporal, inferior, and superior). Solution-related corneal staining was defined as ≥20% corneal staining area in at least 3 corneal regions of both eyes.

Secondary Outcome Measures:
  • Mean Lens Comfort [ Time Frame: Day 7 ]
    Lens comfort was assessed by the participant on a 5-point Likert scale prior to any examination. The participant was instructed to select a single response to the statement, "Over the previous 2-3 hours, my lenses felt comfortable," with 1 = strongly disagree, 2 = disagree, 3 = undecided, 4 = agree, and 5 = strongly agree.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 18 years of age or older.
  • Wear contact lenses a minimum of 8 hours per day for at least 7-10 days prior to Visit 1 (screening visit).
  • Vision correctable to 20/30 (Snellen) or better in each eye at distance with contact lenses at Visit 1.
  • Must discontinue contact lens wear for at least two consecutive days before Visit 2 (baseline visit).
  • Other protocol-specified inclusion criteria may apply.

Exclusion Criteria:

  • Any medical condition (systemic or ophthalmic) that may, in the opinion of the investigator, preclude safe administration of test article or safe participation in the study.
  • Known sensitivity or intolerance to any protocol-specified contact lens solutions, eye drops, or products containing similar ingredients (e.g., generic products).
  • Monocular vision (only one eye with functional vision) or fit with only one contact lens.
  • Use of topical ocular over-the-counter or prescribed topical ocular medication, with the exception of rewetting drops, within 7 days prior to screening visit.
  • Current or history of ocular infection, inflammation, disease, structural abnormality or conditions within the last 6 months that could affect study participation or may preclude safe administration of the investigational lens care solution, in the opinion of the investigator.
  • Any corneal surgery, cataract surgery, intraocular lens implants or glaucoma filtering surgery within the last 12 months.
  • Any slit-lamp finding score of 1 (or rated 3 or 4 for limbal and bulbar conjunctival injection) at screening or baseline visits.
  • Corneal staining area assessment ≥ 20% in any corneal region in either eye at baseline visit.
  • Corneal staining graded as 2 (macropunctate) or greater in any corneal region in either eye at baseline visit.
  • Participation in any investigational clinical study within 30 days of baseline visit.
  • Other protocol-defined exclusion criteria may apply.
