Diaton tonometer is a handheld device that measures IOP through the eyelid & completely  satisfies present-day  requirements of diagnostic equipment.

 

Spheres of diaton tonometer application

  • ophthalmology (including children's)
  • general medical practice
  • optometry
  • neurology

Method for measuring the intraocular pressure through the eyelid and the device realizing this method are protected by the Patent of Russia № 2123798, United States Patent № US 6,394,954 В1 and Patent of Japan №3593314.

Nowadays transpalpebral scleral tonometry has no other  alternative in the world. It is the most favourable method to carry out  preclinical medical research of the population and , moreover,it works in such  complicated clinical cases when it is impossible to use  classical tonometry methods. Diaton is a helpful tool for ophthalmologists faced with pediatric patients or who have corneal abnormalities such as corneal edema, erosions or keratoprostheses. 

Approved by the FDA in 2006, the instrument has been the subject of numerous clinical trials, where it has been found to be comparable with the gold standard, the Goldmann tonometer, and with many other devices.

Innovative approach to IOP measurement opens up wide medical opportunities and undisputable benefits both for doctors &  patients:

for doctors:

  • Accurate results
  • Wide range of medical opportunities
  • Quick & efficient  procedure of measuring (IOP measurement takes several seconds)
  • Сreates an image of a modern doctor working in an up-to-date equipped medical center
  • Wide medical opportunities
  • Low dispensable materials' expenses

for patients:

  • No contact to the cornea
  • No risk of infection
  • No anesthesia drops
  • No pain
  • No need to take out contacts

Transpalpebral "diaton" tonometer is effective and irreplaceable in complicated medical cases:

  • Can measure IOP even in the presence of viral infections, allergic reactions, dry eye syndrome, contraindications for corneal tonometry
  • Can serve as non-invasive day monitoring tool while selecting the adequate hypotensive medical treatment
  • Can measure IOP  on patients after corneal surgeries
  • Сan measure IOP with contact lenses on
  • Can measure IOP on immobilized patients
  • Screening tool for elevated IOP by PCPs
  • Trained family members  can monitor IOPs of glaucoma patients at home
