Comparison of FT-1000 non-contact tonometry with Goldmann applanation tonometry in glaucoma patients
Official title: Comparative Study of the Tomey FT-1000, and Goldmann Applanation Tonometer (GAT)
Run by Tomey Corporation · NCT07804277 · Data updated 2026-11-12
This study tests whether the FT-1000 non-contact tonometer gives measurements that agree with the Goldmann applanation tonometer in adults with glaucoma.

Is this trial a fit for you?
✓Likely a good fit
Adult patients (age 22+) with glaucoma who can undergo both FT-1000 and Goldmann tonometry in a single visit.
✕Probably not a fit
Patients whose IOP measurements differ substantially between devices or with corneal pathology may not benefit from this approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective, single-site observational study conducted in the United States. One eye per participant will be used for primary analysis, with fellow-eye data explored if available. Researchers will measure IOP with both the FT-1000 and Goldmann tonometers during the same visit and summarize results with basic descriptive statistics. The study aims to determine if the FT-1000 can feasibly be used alongside standard tonometry in this patient group.
Why it matters
Potential benefit: If successful, the FT-1000 could provide a quicker, non-contact option for IOP measurement in glaucoma care.
How similar studies have gone: Similar non-contact vs. Goldmann comparisons have been explored before, but this study adds a focused, single-site prospective confirmation.

Show full inclusion / exclusion criteria
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.
