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
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:
Transpalpebral "diaton" tonometer is effective and irreplaceable in complicated medical cases:
|No contact with the cornea||+|
|Displays independence from cornea's crookedness.||
|Digital IOP indication||+||+||+||+|
|Measurement in sitting position||+||+||+||+|
|Measurement in reclining position||+||+||+|
|Sterilization is not required||+||+||+|
|Anesthesia is not required||+||+||+|
