What is being measured

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

  1. Distance Visual Acuity (VA) With Study Lenses

    Distance VA was assessed with study lenses in place. VA was collected for each eye separately using logarithmic of the Minimum Angle of Resolution (logMAR) charts. A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal visual acuity), with a negative value denoting better than 20/20 visual acuity. No formal hypothesis was predefined for the primary endpoint. No inferential testing was performed.

    Measured: Day 8 (-0/+3 days) after 10 (-2/+6) hours of wear, each study lens type

What does the primary outcome measure?

Distance Visual Acuity (VA) With Study Lenses (time frame: Day 8 (-0/+3 days) after 10 (-2/+6) hours of wear, each study lens type). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
