What is being measured

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

  1. End of Day Comfort

    End of day comfort was interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of 5 days of wear. End of day comfort was measured on a 10-point scale, with 1 being poor and 10 being excellent.

    Measured: 5 days of wear, lenses replaced daily

  2. End of Day Dryness

    End of day dryness was interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of 5 days of wear. End of day dryness was measured on a 10-point scale, with 1 being very dry and 10 being not dry.

    Measured: 5 days of wear, lenses replaced daily

  3. Handling at Removal

    Handling at removal was interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of 5 days of wear. Handling at removal was measured on a 10-point scale, with 1 being poor/difficult and 10 being excellent/easy.

    Measured: 5 days of wear, lenses replaced daily

  4. Overall Vision

    Overall vision was interpreted and reported by the participant on a questionnaire as a single, retrospective evaluation of 5 days of wear. Overall vision was measured on a 10-point scale, with 1 being poor and 10 being excellent.

    Measured: 5 days of wear, lenses replaced daily

Secondary outcomes (1)
  1. Overall Fit

    Overall lens fit was assessed by the investigator at study visit using a biomicroscope, which magnifies the appearance of the contact lens on the participant's eye. Lens fit was assessed by eye and graded on a 5-point scale, with 2=unacceptably loose, 1= acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight

    Measured: Day 5, lenses replaced daily
