It's a brand new device that no one has ever used. This device was received as a gift for my father, but has been left for over 5 years without use. I have checked the device, it is fully operational and functional and takes correct measurements. I have compared its values with the values of other IOP pressure measuring devices available to me and they are completely identical. Printed instructions in English included.

Intraocular pressure indicator IGD-02 PRA is designed to measure tonometric intraocular pressure (IOP) through the eyelid in the area of sclera according to Maklakov at a load of 10 g, which allows to completely exclude the impact of the device on the mucous membrane of the eye.

IGD-02 PRA indicator is used in ophthalmology departments of hospitals and neurology, as well as in pre-medical examination rooms. Can be used at home, but the patient can't measure their own IOP without assistance. Requires the assistance of a second person to measure IOP.

- Non-contact principle of work - no impact on the mucous membrane of the eye, which eliminates the risk of infection;
- Possibility to perform the study in any position - lying or sitting;
- Accuracy of readings - the original algorithm of control of the IOP measurement process eliminates accidental errors
- Portability and mobility for use when working in the field;
- Possibility of daily IOP monitoring for medication selection;
- Ability to be used for corneal pathology;
- Availability of a case for easy storage and transportation.
