What is being measured

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

  1. Overall Comfort

    As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 3 months of wear time. Overall comfort was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.

    Measured: 3 months of wear, replacing lenses monthly

Secondary outcomes (1)
  1. Overall Lens Fit

    As 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 graded by eye on a 5-point scale, with 2=unacceptably loose, 1=acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight

    Measured: 3 months of wear, replacing lenses monthly
