Abstract
The present invention provides an acoustic wave intraocular pressure detecting device and a method thereof, which uses a driver to generate a vibration wave on the skin or bones. The energy of the vibration wave is transmitted to the orbital bones via the skin and the skeletons. A standing wave of the basin effect is generated on the eyeball inside the orbital bones. The standing wave vibrates the eyeball or the cornea to generate an acoustic wave signal with a resonance frequency. The eyeball or the cornea emits the acoustic wave outwardly. A receiver receives the acoustic wave and converts the acoustic wave into an intraocular pressure (IOP) value.
