IOP MEASURING DEVICE

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 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:

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).
