The Handheld Diaton Tonometer provides high reliability of measuring results and makes it possible to diagnose glaucoma on the early stage and appoint necessary treatment and medicines.

The unique methodology of intraocular pressure measuring through the eyelid applied in the device provides new resources in ophthalmotonometry, simplicity and safety of tests.
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).

Comparison tests of handheld diaton tonometer tonometer and Goldman tonometer are the evidence of high reliability of diaton tonometer displays.
