Ophthalmic laser apparatus

An ophthalmic laser apparatus, comprising:

• an excimer laser light source configured to generate an excimer laser beam;
• a light guide device configured to guide the excimer laser beam generated from the excimer laser light source;
• a support bracket configured to support a patient's head for an exposed surface of the patient's eye to be perpendicular to a horizontal plane;
• a positioning device configured to acquire a position of the patient's eye, said positioning device producing a positioning result corresponding to the position of the patient's eye;
• a laser beam projector, the laser beam projector being movable for alignment with the patient's eye based on the positioning result produced by the positioning device, wherein the excimer laser beam from the light guide device is projected toward the patient's eye through the laser beam projector for an ophthalmic procedure including Laser-Assisted In Situ Keratomileusis surgery, wherein the laser beam projector includes an eye tracking system and a fine adjustment device, the eye tracking system being configured to track the position of the patient's eye for generation of a repositioning result based on the patient's eye position, the fine adjustment device being operatively coupled to said eye tracking system and to said laser beam projector, wherein said fine adjustment device is configured to adjust a position of the laser beam projector relative to the patient's eye according to the repositioning result of the eye tracking system, thus accurately aligning the laser beam projector with the patient's eye;
• a moving stand, wherein the positioning device and the laser beam projector are disposed on the moving stand, the moving stand being configured to move the positioning device and the laser beam projector along an X direction, a Y direction, and/or a Z direction relative to the patient's eye;
• and
• a controller operatively coupled to the excimer laser light source and the laser beam projector to control the excimer laser light source to irradiate the excimer laser beam and to control the laser beam projector to project the excimer laser beam toward the patient's eye.
