入选标准

  • Must sign the informed consent form.
  • Stable, tear lipid layer thickness ≤ 75 nm without contact lenses.
  • Successfully wearing bi-weekly or monthly replacement soft contact lenses in both eyes for a minimum of 5 days/week during the past 2 months prior to Visit
  • Vision correctable to 20/25 Snellen (feet) or better at distance with habitual contact lenses at Visit
  • Willing to wear lenses 5 days a week, 8 hours a day for at least 2 days during the study.
  • Demonstrate symptoms of contact lens discomfort.
  • Other protocol-defined inclusion criteria may apply.

排除标准

  • Routinely sleeping in lenses.
  • Any active eye inflammation or condition that contraindicates contact lens wear.
  • Any systemic diseases that could prevent successful contact lens wear.
  • Use of systemic or ocular medications that contraindicate lens wear.
  • Fit with only 1 contact lens.
  • Unwilling to discontinue the use of cosmetics (such as eyeliner, mascara, or eye shadow) or facial creams on or around the eyelids on Day 1 and Day 14 of the study.
  • Women of childbearing potential who are currently pregnant, test positive for pregnancy at Screening visit, breast feeding, or unwilling to use adequate birth control throughout the study.
  • Other protocol-defined exclusion criteria may apply.

结局指标

主要结局

Mean Pre-lens Tear Lipid Layer Thickness After 2 Hours of Lens Wear on Day 1

时间窗: Day 1, after 2 hours of lens wear

The pre-lens tear film is the layer of tears located on top of the contact lens (i.e., between the eye lid and the contact lens). The anterior-most layer of the pre-lens tear film consists of lipids. Lipid layer thickness (LLT) is measured with the LipiView® Interferometer. LLT is measured in interferometric color units (ICUs), where 1 ICU reflects about 1 nanometer (nm) lipid layer thickness. Higher values of LLT indicate a better lubrication of the ocular surface. A thicker tear lipid layer helps reduce evaporation and is indicative of a more stable tear film. The right eye only was used for this measure.

次要结局

  • Mean Comfortable Lens Wear Time (Time Uncomfortable - Time Insertion) at Baseline and Day 14(Baseline (Day 0), Day 14)
  • Percentage of Participants That Experienced At Least 1 Unit Increase From Baseline Score to Day 14 for Overall Comfort With Lenses(Baseline (Day 0), Day 14)
  • Mean Change From Baseline in Comfortable Lens Wear Time (Time Uncomfortable - Time Insertion) to Day 14(Baseline (Day 0), Day 14)
  • Mean Pre-lens Tear Lipid Layer Thickness After 2 Hours of Lens Wear on Day 14(Day 14, after 2 hours of lens wear)
