Outcome Measures

Primary Outcomes (2)

  • Average Corneal Staining Area

    Percentage corneal staining was assessed by the investigator for each of five regions of the cornea, i.e., four quadrants plus central. The investigator instilled fluorescein dye and examined the cornea with a slit lamp, i.e., biomicroscope and a yellow filter. Percentage corneal staining area was recorded in increments of ten, and the percentages of the five regions were averaged together.

    After 2 hours of wear

  • Total Corneal Staining Type

    Total corneal staining type was assessed by the investigator for each of 5 regions of the cornea, i.e., four quadrants plus central. The investigator instilled fluorescein dye and examined the cornea with a slit lamp, i.e., biomicroscope and a yellow filter. Corneal staining type was recorded on a 5-point scale for each region: 0-none; 1-micropunctate; 2-macropunctate; 3-coalesced macropunctate; 4-patch (\>/= 1mm). The five regions were summed.

    After 2 hours of wear

Secondary Outcomes (2)

  • Ocular Comfort

    After 2 hours of wear

  • Ocular Redness

    After two hours of wear
