About this study

This study is intended to evaluate the agreement between Intraocular pressure(IOP) measurements obtained with the FT-1000 non-contact tonometer and a GAT to confirm the feasibility of the measurement procedures.

This is a prospective comparative study that will be conducted at one clinical site in the United States. Subjects who sign an informed consent form and fulfill all inclusion and exclusion criteria will undergo FT-1000 measurements followed by Goldmann applanation tonometry during a single study visit.

The primary analysis will be performed using one preselected study eye from each subject. Measurements from the fellow eye, when available, may be summarized as exploratory analyses but will not contribute to the primary effectiveness analysis.

In general, descriptive statistics (n, mean, standard deviation, median, minimum and maximum) will be used to summarize continuous variables. Frequencies and percentages will be used to summarize categorical variables. The number of accepted scans and the total number of scans evaluated will be summarized by scan type, device, and subject population.

Agreement between the FT-1000 and the Goldmann applanation tonometer will be evaluated using the study eye measurements by calculating the mean difference, standard deviation (SD), 95% limits of agreement (LOA), Bland-Altman plots, Deming regression, and Pearson correlation coefficient.

Exploratory analyses may also be performed using fellow-eye measurements.

What is being measured

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

  1. Agreement of the Intraocular pressure (IOP) mmHg between the test devices and predicate device

    Agreement of the Intraocular pressure (IOP) mmHg between the FT-1000 and the Goldmann Applanation Tonometer(GAT) will be evaluated using the study eye measurements by calculating the mean difference, standard deviation (SD), 95% limits of agreement (LOA), Bland-Altman plots, Deming regression, and Pearson correlation coefficient.

    Exploratory analyses may also be performed using fellow-eye measurements.

    Measured: Through study completion, approximately 3 days

  2. Safety of the test devices

    Any adverse events observed or reported during the study visit will be assessed and documented.

    Measured: Through study completion, approximately 3 days

Questions about this trial

What is this clinical trial studying?

An observational study of Glaucoma, run by Tomey Corporation at 1 site 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 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: looking for participants now, as of the sponsor's last update on 6 Oct 2026. 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 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?

This study is still under way. Results are not available in the source record yet.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Agreement of the Intraocular pressure (IOP) mmHg between the test devices and predicate device (time frame: Through study completion, approximately 3 days). 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 6 Oct 2026.
