Abstract
An ultrasonic tonometer, which measures an intraocular pressure of a subject eye using an ultrasonic wave, has an ultrasonic actuator including an ultrasonic element that generates an ultrasonic wave and a sonotrode that propagates the ultrasonic wave generated from the ultrasonic element, and irradiating the subject eye with the ultrasonic wave. The sonotrode includes an uneven portion in which a thickness of the sonotrode varies in a sound axis direction of the ultrasonic wave.
Claims8
An ultrasonic tonometer that measures an intraocular pressure of a subject eye using an ultrasonic wave, comprising:
- an ultrasonic actuator including an ultrasonic element that generates an ultrasonic wave and a sonotrode that propagates the ultrasonic wave generated from the ultrasonic element, and irradiating the subject eye with the ultrasonic wave,
