What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT05741450
Study groupRoleWhat they receive
Lens 1ExperimentalAll participants wore Lens 1 for 15 minutes (Period 1)
Receives: Device: Lens 1 (monthly replacement)
Lens 2ExperimentalAll participants wore Lens 2 for 15 minutes (Period 2)
Receives: Device: Lens 2 (daily disposable)

What is being measured

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

  1. Subjective Overall Score

    Subjective overall score was assessed using 0-100 visual analogue scale, where 0=Extremely poor, cannot use lenses and 100=Excellent, highly impressed with these lenses overall

    Measured: 15 minutes

Secondary outcomes (2)
  1. Subjective Comfort

    Subjective comfort score was assessed using 0-100 visual analogue scale, where 0=Causes pain, cannot be tolerated and 100=Excellent, cannot be felt

    Measured: 15 minutes

  2. Subjective Vision

    Subjective vision score was assessed using a 0-100 visual analogue scale, where 0=Unacceptable, lens cannot be worn and 100=Excellent, unaware of any visual loss

    Measured: 15 minutes
