  • Is willing and able to follow instructions and maintain the appointment schedule;
  • Habitually wears soft contact lenses in daily wear, for minimum of 6-months;

  • Can be fit with study contact lenses with a power between -2.00 and -5.00 DS;
  • Demonstrates an acceptable fit with the study lenses;
  • Habitually wears single vision soft contact lenses for at least 8 hours per day, 5 days a week, and is willing to wear contact lenses for at least 12 hours a day in the study.

Who cannot join

  • Is participating in any concurrent clinical or research study;
  • Has any known active* ocular disease and/or infection;
  • Has a systemic condition that in the opinion of the investigator may affect a study outcome variable;
  • Is using any systemic or topical medications that in the opinion of the investigator may affect a study outcome variable;
  • Has known sensitivity to the diagnostic pharmaceuticals to be used in the study;
  • Is pregnant, lactating or planning a pregnancy at the time of enrolment because the associated hormonal changes cause changes in the tear layer which impact contact lens comfort. Verbal confirmation at the screening visit is sufficient;

About this study

The objective of the study is to evaluate and compare the performance of study test lens to study control lens, when worn on a daily disposable modality over a period of approximately one week each

Read the detailed description

The study is a prospective, double masked (investigator and participant), bilateral, randomized,one week cross-over dispensing study, which evaluates the study test lens and control lens.

What participants receive

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

  • Test Contact LensDevice

    Also called stenfilcon A

    Subjects will be randomized to wear test lenses.

  • Control Contact LensDevice

    Also called verofilcon A

    Subjects will be randomized to wear control lenses.

What is being measured

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

  1. Overall Lens Fit Acceptance

    Overall fit acceptance (0-4, 0.50 steps) (0 - lens should not be worn at all,1 - Borderline but unacceptable, 2 - Minimally acceptable, 3 - Not perfect but OK to dispense, 4 - Perfect)

    Measured: 1 week

Secondary outcomes (6)
  1. Lens Centration

    Lens Centration was measured on a scale (0-3) (0 = "Optimally centered", 1 = "Slightly decentered", 2 = Moderate decentration but not encroaching limbus, 3 = "Excessive \& occasionally encroaching limbus")

    Measured: Baseline

  2. Lens Centration

    Lens Centration was measured on a scale (0-3) (0 = "Optimally centered", 1 = "Slightly decentered", 2 = Moderate decentration but not encroaching limbus, 3 = "Excessive \& occasionally encroaching limbus")

    Measured: 1 week

  3. Post-blink Movement

    Post-blink lens movement was measured using an eyepiece reticule while viewing the contact lens in-vivo at 8x magnification in primary gaze, in 0.1mm steps

    Measured: Baseline

  4. Post-blink Movement

    Post-blink lens movement was measured using an eyepiece reticule while viewing the contact lens in-vivo at 8x magnification in primary gaze, in 0.1mm steps

    Measured: 1 week

  5. Push-up Tightness

    Push-up tightness in primary gaze measured on a scale (0-100, 5% steps) (0% = falls from cornea without lid support, 50% = optimum, 100% = no movement)

    Measured: Baseline

  6. Push-up Tightness

    Push-up tightness in primary gaze measured on a scale (0-100, 5% steps) (0% = falls from cornea without lid support, 50% = optimum and 100% = no movement)

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

A study testing Test Contact Lens in people with Myopia, run by CooperVision, Inc. at 1 site in Canada.

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 9 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. 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 21 Jun 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?

Overall Lens Fit Acceptance (time frame: 1 week). 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 23 Jun 2021.
