Diaton tonometer is the only one device for intraocular pressure measuring through the upper eyelid. It completely meets modern diagnostic equipment requirements.
Method for measuring the intraocular pressure through the eyelid and device for realizing the same are protected with the Patent of Russia No 2123798, United States Patent No US 6,394,954 ?1 and Patent of Japan No3593314.
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:
|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||+||+|
Comparison tests of diaton tonometer and Goldman tonometer are the evidence of high reliability of diaton tonometer displays.
