What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall Comfort

    Subjects rated study contact lens for overall comfort using the following scale: 5=excellent, 4=very good, 3=good, 2=fair, 1=poor.

    Measured: 1 week

Secondary outcomes (4)
  1. Inferior Region Corneal Staining

    The investigator assessed abrasion to the lower portion of the cornea using the following scale:0 = None 1 = Slight micropunctate (1-10 spots) 2 = Moderate micropunctate (11-20 spots) 3 = Severe micropunctate (>20 spots)4 = Slight macropunctate (1-5 spots) 5 = Moderate macropuntate (>5-10 spots) 6 = Severe macropunctate (>10 spots) 7 = Slight patch (1-2mm)8 = Moderate patch (>2-4mm) 9 = Severe patch (>4mm)

    Measured: 1 week

  2. End of the Day Comfort

    Subjects rated study contact lens comfort at the end of a day of lens wear using the following scale: 5=excellent, 4=very good, 3=good, 2=fair, 1=poor.

    Measured: 1 week

  3. Initial Comfort

    Subjects rated study contact lens for comfort immediately when they first put the lenses on using the following scale: 5=excellent, 4=very good, 3=good, 2=fair, 1=poor.

    Measured: 1 Week

  4. Overall Lens Handling

    Subjects rated study contact lens for overall ease of handling using the following scale: 5=excellent, 4=very good, 3=good, 2=fair, 1=poor.

    Measured: 1 week
