Diaton tonometer is the only one device for intraocular pressure measuring through the upper eyelid. It completely meets modern diagnostic equipment requirements.
Fields of diaton tonometer application
ophthalmology (including children's)
general medical practice
optometry
neurology
Method for measuring the intraocular pressure through the eyelid and device for realizing the same are protected with the Patent of Russia № 2123798, United States Patent № US 6,394,954 В1 and Patent of Japan №3593314.
Currently, transpalpebral scleral tonometry has no alternative and is the most optimum method when carrying out prophylactic medical examination of the population and in complicated clinical cases when the use of classical tonometry methods is impossible.
Innovative approach to IOP measurement opens up wide clinical possibilities and unquestionable advantages to the doctor and to the patient:
for the doctor:
accurate tonometry result,
wide clinical possibilities,
image of modern doctor and health center,
quickness and efficiency (no disposables, IOP measurement takes several seconds),
spectrum service spreading.
for the patient:
safety,
quickness,
comfort,
painless,
no necessity to take off contact lenses
Transpalpebral "diaton" tonometer is effective and irreplaceable in various situations:
screening examinations of the patients
IOP control during selection of adequate medicines
IOP measuring in the presence in a patient of chronical conjunctivitis, erosions, edema and cornea dimness
IOP measuring in patients after corneal surgeries
ophthalmotone day monitoring
IOP measuring in immobilized patients and in children
IOP measuring during contact correction (lenses are not taken out).
