What is being measured

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

  1. Comfort

    Comfort of lenses (VAS 0-10, 0,5 steps) after insertion, subjects will be graded on a scale from 0 to 10 with 0=painful, 10= can't feel the lenses

    Measured: 1 week

  2. Comfort

    Comfort of lenses (VAS 0-10, 0,5 steps) after insertion, subjects will be graded on a scale from 0 to 10 with 0=painful, 10= can't feel the lenses

    Measured: 1 month
