Abstract: 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.

Abstract: A CPU of an eyeglass-prescription assisting apparatus is configured to obtain measurement data on an examinee's eye measured by a wavefront sensor, including first distribution data on a refractive error distribution of an examinee's eye and second distribution data on a refractive power distribution in an eyeglass lens to correct the refractive error of the examinee's eye. The CPU further makes arithmetic processing to obtain third distribution data on a refractive error distribution taking correction with the eyeglass lens into consideration based on the first distribution data and the second distribution data.

Abstract: 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.

Abstract: Provided is an ophthalmic apparatus for examining an examinee's eye, including: an examination device configured to examine the examinee's eye; an approacher in the examination device, configured to approach the examinee; a detector configured to detect approach of the approacher to the examinee; and a controller configured to switch an operation mode between a first mode where an avoidance operation for avoiding the approach is performed and a second mode where the avoidance operation is not performed, upon the detector detecting the approach.
