Abstract: An ophthalmic laser treatment apparatus for generating plasma by focusing a treatment laser beam to treat a treatment target portion of a patient's eye with the plasma includes: an irradiation optical system configured to irradiate the treatment laser beam to the patient's eye; a position adjusting unit configured to adjust a focusing position of the treatment laser beam in an optical axis direction with respect to a predetermined focusing reference position; an energy adjusting unit configured to adjust irradiation energy of the treatment laser beam; a storage unit configured to store evaluation information to evaluate a permissible combination of the focusing position and the irradiation energy with respect to the focusing position; and an evaluation unit configured to evaluate a combination of the focusing position adjusted by the position adjusting unit and the irradiation energy adjusted by the energy adjusting unit based on the evaluation information.

Abstract: A laser treatment apparatus configured to emit laser light onto a tissue of a patient's eye, the laser treatment apparatus includes: a laser scanner configured to scan laser light emitted from a laser light source and switch a position of the tissue onto which laser light is emitted; a processor; and memory storing computer readable instructions, which are executed by the processor, causing the laser treatment apparatus to: (a) emit the laser light onto a first spot; (b) stop emitting the laser light onto the first spot for a stop time; (c) emit the laser light onto at least one second spot other than the first spot during the stop time; (d) emit the laser light onto the first spot again after the stop time elapses; and repeat (b), (c) and (d) several times to execute intermittent irradiation treatment onto a plurality of spots multiple times.

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.
