An observational study of Glaucoma and Ocular Hypertension, run by Intuor Technologies, Inc. at 2 sites in United States.
Trial summary
The CATS Tonometer prism clinical study is intended to determine repeatability of intraocular pressure measurement in human corneas which have undergone a LASIK procedure when compared to a standard Goldmann prism, validating the human LASIK eye findings comparing CATS Tonometer and Goldmann prisms to intracameral… Read more about this study

Questions about this trial
What is this clinical trial studying?
An observational study of Glaucoma and Ocular Hypertension, run by Intuor Technologies, Inc. at 2 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 3 inclusion and 12 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 5 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
IOP measurement difference between CATS and GAT in LASIK patients (time frame: single measurement 1 day). 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 5 Nov 2024; AzTrials last refreshed its copy on 7 Nov 2026.
