This device can be used not just in hospitals but also at home. The device is easy in use and you don’t need special education to use it.

ТVGD-02 has two IOP measuring modes:

  • tonometric IOP measurement mode (Maklakov tonometer scale); 
  • true IOP measurement mode (Goldmann tonometer scale).
The device has the following advantages:

  • The time of measurement is just 1-2 seconds.
  • The high accuracy of the measurements.
  • Makes it possible to measure IOP through the eyelid both in the sclera and in the cornea.
  • The device has a self-test feature.
  • During the measurement process the cornea of the eye isn't touched by the device that excludes the infection.
  • To take measurements both in sitting or prone position.
  • The soft measurement rod impact provides maximum patient comfort.
  • ТVGD-02 ensures quick, accurate and painless measurements even for hypersensitive patients or children.

With TVGD-02 you get easy, safe and accurate IOP pressure measurements at any time and in any place.
