A non-contact ultrasonic tonometer for measuring the eye pressure of an examinee's eye by use of ultrasound includes a Langevin transducer. The Langevin transducer applies ultrasound to the examinee's eye to measure the eye pressure of the examinee's eye. Further, A non-contact ultrasonic tonometer for measuring the eye pressure of an examinee's eye by use of ultrasound includes: ultrasonic generating means for generating ultrasound; a support base supporting the ultrasonic generating means; and attaching means for attaching the ultrasonic generating means to the support base.

Non-contact ultrasonic ophthalmotonometer

An ultrasonic tonometer for measuring the eye pressure of an examinee's eye by means of an ultrasonic wave includes an ultrasonic actuator having an ultrasonic element and configured to irradiate the examinee's eye with the ultrasonic wave, and current adjustment means configured to adjust a current applied to the ultrasonic element to control the sound pressure or acoustic radiation pressure of the ultrasonic wave. With this configuration, the ultrasonic tonometer solving at least one of typical problems can be provided. For example, the ultrasonic tonometer capable of properly irradiating the examinee's eye with the ultrasonic wave can be provided.

Ultrasonic tonometer

Provided is a method for an ophthalmic examination by an ophthalmic examination system including an ophthalmic examination apparatus and an examiner-side apparatus that is connected to the ophthalmic examination apparatus by a network and is provided with an interface for input/output, the method including: a transmission step of transmitting an error signal from the ophthalmic examination apparatus to the examiner-side apparatus upon occurrence of an error in the ophthalmic examination apparatus; a selection step of, upon the examiner-side apparatus receiving the error signal, notifying an examiner of the occurrence of the error via the interface and also accepting selection input for selecting any of a plurality of predetermined handling methods of the error; a response step of the examiner-side apparatus transmitting a response signal to the ophthalmic examination apparatus on the basis of the selection input; and a notification step of, upon the ophthalmic examination apparatus receiving the response signal, notifying the examinee of guidance information on the action against the error on the basis of the response signal via an output device.
