What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether the Tomey FT-1000, a non-contact tonometer that measures eye pressure with a puff of air, agrees with the standard Goldmann applanation tonometer, which touches the eye. Researchers will enroll 30 adults with glaucoma and measure eye pressure with both devices during one visit. The goal is to see if the FT-1000 can be a reliable alternative for monitoring eye pressure.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Tomey FT-1000 non-contact tonometer
What this could lead to
If the FT-1000 matches the Goldmann tonometer's accuracy, it could offer a faster, non-contact way to measure eye pressure in glaucoma care.
What could go wrong
This is a small, early study with 30 participants. The device may not match the Goldmann tonometer's precision, and results may not apply to broader populations.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Male or female subjects 22 years of age or older who have full legal capacity to volunteer on the date the informed consent is signed. 2. Subjects who are able to understand and follow the study procedures and instructions provided by the clinical staff. 3. Subjects who voluntarily provide written informed consent. 4. Subjects who satisfy all study eligibility requirements and are able to undergo both FT-1000 and Goldmann applanation tonometry measurements during the study visit. Exclusion Criteria: 1. Subjects with only one functional eye. 2. Subjects with poor or eccentric fixation in either eye. 3. Subjects with a history of corneal surgery, including corneal laser or refractive surgery (e.g., LASIK). 4. Subjects with corneal scarring, keratoconus, or any other clinically significant corneal pathology. 5. Subjects with an active corneal or conjunctival infection or inflammation in either eye. 6. Subjects with microphthalmos or buphthalmos. 7. Subjects who are unable or unwilling to remove contact lenses before study measurements. 8. Subjects with clinically significant dry eye disease that, in the investigator's opinion, may affect tonometry measurements. 9. Subjects with blepharospasm (lid squeezing) or nystagmus that may interfere with accurate measurements. 10. Subjects with abnormal central corneal thickness (CCT). 11. Subjects with any condition or circumstance that, in the opinion of the investigator, could place the subject at significant risk, interfere with study participation, or confound interpretation of the study results.
