Primary outcomes

  1. On-eye Wettability

    Time frame: 4 weeks of wear

    On-eye wettability, as assessed at the 4-week visit by a masked observer from a video taken of the eye 5 minutes after lens insertion. On-eye wettability was recorded on a 5-point scale, with 0=excellent and 4=very poor.
