Abstract
An ophthalmic laser treatment apparatus includes: an irradiation optical system including an optical scanner for two-dimensionally scanning spots of a treatment laser beam and an aiming beam on eye tissue; a control unit to control the irradiation optical system to irradiate the treatment beam to a spot position based on an irradiation pattern of spots for treatment beam irradiation and based on an aiming rule associated with the irradiation pattern to irradiate the aiming beam to indicate the treatment beam spot position; and a movement unit to move an irradiation position of each beam. The control unit irradiates the treatment beam to a sequence of spots from a n-th position to a m-th position in association with the irradiation pattern, and then controls the movement unit and irradiates the aiming beam based on the aiming rule to a position different from the spot position just irradiated by the treatment beam.
