PROBLEM TO BE SOLVED: To execute accurately and easily aiming for focusing of a laser beam by image processing aiming light imaged by an imaging means, judging an aiming condition on the basis of the result of image processing and notifying an operator of the result of judgment by a notification means. SOLUTION: When executing laser operation for crushing a posterior capsule or the like in the treatment of a secondary cataract, first by using a control section 3, laser irradiation conditions such as an output or the like of a laser beam are set. Subsequently by operating a joystick 4, a body 1 is moved and adjusted so that a patient eye may be shown on a display 5. Namely, while jogging the joystick 4, two aiming beams 50a and 50b reflected onto a site to be treated that is shown on the display 5 are superposed. In the image processing section, the conditions of the aiming beams 50a and 50b are analyzed, and when it is confirmed that the two aiming beams 50a and 50b have been superposed on each other, the alphabet 'OK' or a specified graphic is displayed on the display 5. |
