Abstract
An ophthalmic surgery apparatus comprising a system for observing an anterior portion of an eye, and an optical system for irradiating a laser beam for treatment to the eye, the apparatus is a corneal surgery apparatus irradiating the laser beam to a cornea and ablating a surface thereof, the apparatus comprising a moving device for moving the optical system relatively against the eye, an illuminating device for illuminating a large area of the anterior portion of the eye, a photoelectric transducing device having a two-dimensional light sensing plane, for sensing distribution of light volume of the anterior portion of the eye, a pupil position sensing device for sensing the position of a pupil, a control device for controlling the moving device based on sensed results, a tracking signal generating device for generating a signal to track movement of the eye, whereby the moving device is controlled by the control device so as to track movement of the eye by inputting a signal generated by the tracking signal generating device, and a device for prohibiting irradiation of the laser beam in the case that the position of the pupil misses the predetermined limits.
