What participants receive

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

  • Lens 1 (ocufilcon D)Device

    15 minutes of daily wear

  • Lens 2 (somofilcon A)Device

    15 minutes of daily wear

Study groups in NCT06758089
Study groupRoleWhat they receive
Lens 1 (ocufilcon D)ExperimentalAll participants will wear lens 1 for 15 minutes (Period 1).
Receives: Device: Lens 1 (ocufilcon D)
Lens 2 (somofilcon A)ExperimentalAll participants will wear lens 2 for 15 minutes (Period 2).
Receives: Device: Lens 2 (somofilcon A)

What is being measured

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

  1. Subjective Overall Score

    The primary outcome measure for this study is the subjective overall score on a scale of 0-100. (0 = Extremely poor. Unmanageable. Cannot use lenses. 100 = Excellent. Highly impressed with these lenses overall.)

    Measured: At the end of 15 minutes of daily wear

Secondary outcomes (2)
  1. Subjective Vision

    The secondary outcome measure for this study is the subjective vision on a scale of 0-100. (0 = Extremely poor. Intolerable. Lenses cannot be worn. 100 = Excellent. Unaware of any visual loss.)

    Measured: At the end of 15 minutes of daily wear

  2. Subjective Comfort

    The secondary outcome measure for this study is the subjective comfort on a scale of 0-100. (0 = Extremely uncomfortable. Causes pain. Cannot be tolerated. 100 = Excellent. Cannot be felt.)

    Measured: At the end of 15 minutes of daily wear

Questions about this trial

What is this clinical trial studying?

A study testing Lens 1 (ocufilcon D) and Lens 2 (somofilcon A) in people with Astigmatism, run by CooperVision International Limited (CVIL) at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Subjective Overall Score (time frame: At the end of 15 minutes of daily wear). 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Feb 2026.
