About this study

Demonstrate that refraction measurements from the device agree with refraction measurements from a phoropter within clinically meaningful limits.

Read the detailed description

The primary purpose of this study is to attain scientific objective evidence to support the VisionCheck Indications for Use by demonstrating that refraction measurements from the device agree with refraction measurements from a phoropter within clinically meaningful limits. The Indications for Use are:

"The EyeQue VisionCheck automated subjective refraction system provides an estimate of sphere, cylinder, and axis measurements of the eye"

Furthermore, the purpose of this study is to attain scientific objective evidence regarding the precision of the VisionCheck device.

What participants receive

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

  • EyeQue VisionCheckDevice

    Automated subjective refraction system provides estimates of sphere, cylinder, and axis measurements of the eye.

  • PhoropterDevice

    Standard of care, ophthalmic testing device, used by eye care professionals to measure the refractive error of the eye and determine prescription.

VisionCheckActive comparatorSelf-administered refraction performed using the EyeQue VisionCheck device.
Receives: Device: EyeQue VisionCheck

What is being measured

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

  1. Assess agreement between the VisionCheck refraction measurement and a phoropter (standard of care) refraction measurement.

    Bland-Altman limits of agreement (LoA) for within-eye differences between refraction measurements of sphere, cylinder, and axis obtained from VisionCheck and the subjective phoropter

    Measured: 3 months

  2. Assess total variability and variance components for between- replicates (repeatability) and between-device/operator while adjusting for between-participant and between-site variability.

    Percent coefficient of variation (%CV) and standard deviation (SD) of refraction measurement outputs in the form of sphere, cylinder, and axis obtained from VisionCheck

    Measured: 3 months

Secondary outcomes (2)
  1. Assess improvement in visual acuity brought forth by the VisionCheck refraction measurement.

    95% upper prediction limit of improvement in visual acuity from refraction measurements obtained from VisionCheck compared to best corrected visual acuity from the subjective phoropter

    Measured: 3 months

  2. Assess the safety of the VisionCheck device.

    Adverse events (AEs), serious adverse events (SAEs), adverse device effects (ADEs), serious adverse device effects (SADEs), anticipated and unanticipated serious adverse device effects (ASADEs and USADEs, respectively)

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing EyeQue VisionCheck and Phoropter in people with Refractive Errors and Astigmatism, run by EyeQue Corp..

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 6 inclusion and 27 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: status not confirmed, as of the sponsor's last update on 21 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact Noam Sapiens, PhD (510-455-8168, noam.sapiens@eyeque.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assess agreement between the VisionCheck refraction measurement and a phoropter (standard of care) refraction measurement. (time frame: 3 months). The study lists 2 primary outcomes in all. 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 21 Sep 2023.
