Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Supportive Care
Official Title: Wettability of Silicone Hydrogel Lenses With SiH MPDS FID 114675A vs. A Marketed Multi-Purpose Solution

Primary Outcome Measures:
  • Mean Ex-Vivo Wetting Angle [ Time Frame: Day 7, Hour 14 ]
    Study lens was removed from the eye according to protocol-specified procedures. The OCA15 (Optical Contact Angle) Instrument was used to observe, record, and calculate contact angle measurements. The wetting angle measurement was recorded in degrees (0-180), and a lower wetting angle measurement indicates a more wettable lens.


Secondary Outcome Measures:
  • Mean Lens Comfort [ Time Frame: Day 7, Hour 14 ]
    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, "My lenses feel comfortable right now," with 1 = strongly disagree, 2 = disagree, 3 = undecided, 4 = agree, and 5 = strongly agree.

  • Percentage of Participants With Solution-Related Corneal Staining [ Time Frame: Day 7, Hour 14 ]
    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 and is reported as a percentage of total participants.

Criteria

Inclusion Criteria:

  • 18 years of age or older.
  • Must be successfully wearing assigned study lens brand (either ACUVUE® OASYS™ or PureVision® contact lenses) for at least 7-10 days, minimum 8 hours a day, prior to Visit 1 (screening).
  • Vision correctable to 20/30 (Snellen) or better in each eye at distance with study lenses at Visit 1 (screening).
  • Must have discontinued contact lens wear for at least two consecutive days before Visit 2 (baseline).
