EYE TONOMETRY METHOD Russian patent published in 2018 - IPC A61B3/16 A61B5/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely, to ophthalmology, and can be used for eye tonometry. Affect the eye with a vibrating sensor. Approach the vibrating sensor to the eye before contact with it. Act on their eyes until the signal disappears at the output of the vibrating sensor. Remove the vibrating sensor from the eye and measure the amplitude of the signal at the output of the vibrating sensor. Normalized equivalent is the spectral calibration characteristic ƒ(ω) with amplitude parameters a_n, b_n, which are formed by the Fourier transform of the amplitude-time characteristic approximated by the signal amplitudes. Comparing the amplitude parameters a_n, b_n spectral characteristic ƒ(ω) with parameters a_n0, b_n0 equivalent ƒ₀(ω) of a healthy person, judge the ophthalmotonus.

EFFECT: method provides an increase in metrological efficiency, namely, the accuracy of tonometry due to the reduction of the methodological and the elimination of the dynamic error.
