Abstract:
1. A laser corneal surgery apparatus for ablating a cornea of a patient's eye by a laser beam, comprising: a body having an opening; an observation optical system for observing the patient's eye; an irradiation optical system which is disposed in the body, for irradiating the laser beam onto the cornea through the opening; a movable protection plate for preventing water from adhering to an optical member which is included in the irradiation optical system and disposed at a position located nearest to the opening; an inserting and removing mechanism unit that inserts the protection plate into the opening when the water is used on the patient's eye and removes the protection plate from the opening when the laser beam is irradiated onto the cornea; a sensor that detects whether the protection plate is removed from the opening or is inserted into the opening; and a control unit that controls the irradiation optical system to permit irradiation of the laser beam when the protection plate is removed from the opening based on a result of the detection by the sensor.
