What is being measured

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

  1. Mean Distance Visual Acuity (logMAR) With Study Lenses

    Visual acuity (VA) was collected for each eye individually with study lenses in place at a distance of 4 meters using a letter chart. VA was measured in logarithm minimum angle of resolution (logMAR). On Day 30, VA was assessed after 6-8 hours of wear. A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with a lower logMAR value indicating better visual acuity. No formal hypothesis testing was planned.

    Measured: Day 1, Day 30 after 6-8 hours of wear, each product

Questions about this trial

What is this clinical trial studying?

A study testing Lehfilcon A contact lenses, Comfilcon A contact lenses and CLEAR CARE in people with Myopia, run by Alcon Research at 5 sites in United States.

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

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 26 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Oct 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Mean Distance Visual Acuity (logMAR) With Study Lenses (time frame: Day 1, Day 30 after 6-8 hours of wear, each product). 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 26 Oct 2021.
