Abstract:
A non-contact type tonometer includes: a measurement unit including a first measuring unit for measuring an eye pressure of an examinee's eye in a non-contact manner and a second measuring unit for measuring a corneal thickness of the examinee's eye in a non-contact manner; a moving mechanism for causing relative movement of the measurement unit with respect to the examinee's eye; a drive controller for driving the moving mechanism for aligning the measurement unit; and a setting switch controller for switching an alignment reference on the cornea used for aligning the measurement unit between first and second alignment references. The first alignment reference is a reference for measuring the eye pressure with the first measuring unit and the second alignment reference is a reference for measuring the corneal thickness with the second measuring unit and set closer to a corneal rear surface than the first alignment reference.
