Unique method of IOP measurement combines original approaches to eye tonometry: transpalpebral (measurement through the eyelid) and scleral (measurement is realized in sclera area but not in cornea area)

Fields of application:

  • ophthalmology (including children’s)
  • optometry
  • general medical practice (family medicine)
  • neurology

Indication for application:

  • Screening examinations

  • image of modern doctor and health centre
  • services spectrum spreading

For the patient:

  • quickness
  • safety
  • painless
  •  no necessity to take off contact lenses

Method for measuring the intraocular pressure through the eyelid and device for realizing the same are protected with the Patent of Russia в„– 2123798, United States Patent в„– US 6,394,954 Р’1 and Patent of Japan в„–3593314.
