OCULAR AXIAL LENGTH MEASUREMENT APPARATUS

摘要

An ocular axial length measurement apparatus is provided with: a measurement section for obtaining the ocular axial length of an examinee's eye by using an optical interferometer; a drive mechanism for adjusting the relative positions of the measurement section and the examinee's eye; an operation section operated by an examiner; and a control unit. The ocular axial length measurement apparatus is equipped with an ultrasonic probe for obtaining length information in an axial direction of the examinee's eye in advance, or configured to mount the ultrasonic probe. The control unit, when measuring the eye using the ultrasonic probe, changes a setting at the time of measuring the eye using the ultrasonic probe based on an operation signal output from the operation section.

1. An ocular axial length measurement apparatus comprising:
a measurement unit including a measuring optical system with an optical interferometer for optically measuring the ocular axial length of an examinee's eye in a contactless manner, and an imaging optical system for capturing an anterior segment observation image; a drive mechanism for adjusting the relative positions of the measurement unit and the examinee's eye; an operation section operated by an examiner so as to drive the drive mechanism or the measurement unit; a monitor capable of displaying the anterior segment observation image; and a controller that controls the measurement unit and the driving of the drive mechanism based on an operation signal output from the operation section, wherein the controller, in a state in which a ultrasonic probe for obtaining length information in an axial direction of the examinee's eye is mounted in advance or attached via a cable, changes a setting at the time of measuring the examinee's eye by controlling the ultrasonic probe based on an operation signal input from the operation section.
