摘要： A measuring unit is mounted on a movable stage, which is movable in the right-left and front-rear directions relative to a fixed base stage. When an examiner moves the movable stage to the right or to the left by manipulating a joy stick, a micro switch detects that movement. Upon reception of a detection signal from the micro switch, a microcomputer allows power to be supplied to measurement circuits, to initiate a measurement mode. When judging that proper alignment has been established, the microcomputer automatically calculates a cornea shape. Measurement and calculation of a cornea shape are repeated until a standard deviation of measurement data falls within a given value. Upon completion of the measurement operation, the microcomputer stops the supply of power to the measurement circuits, to cancel the measurement mode.
