Abstract
A laser surgery apparatus is provided to minimize a burden on a patient and to obtain a good result of a surgical operation. The laser surgery apparatus for performing surgery on a patient's eye by irradiating a laser beam thereonto comprises an irradiation device provided with an irradiation optical system for irradiating the laser beam onto the patient's eye, a control device for controlling the irradiation device, and an informing device for informing the patient of at least either a first period of a laser irradiation period or a second period of the laser irradiation period or both.
Claims16
A laser surgery apparatus for performing surgery on a patient's eye by irradiating a laser beam thereonto comprising:
- irradiation means provided with an irradiation optical system for irradiating the laser beam onto the patient's eye;
- eye fixation target presenting means for presenting an eye fixation target for the patient's eye fixation;
- computing means for computing control data based on data on conditions for a surgical operation and for dividing an operation period into a first period and a second period, the first period during which the patient's eye fixation is important and the second period during which the patient's eye fixation is relatively not important compared to the first period;
- control means for controlling the irradiation means based on the computed control data;
- and
- informing means for informing the patient of at least either that an operation step is in the first period or that the operation step is in the second period or both.
A laser surgery apparatus for performing surgery on a patient's eye by irradiating a laser beam thereonto comprising:
- irradiation means provided with an irradiation optical system for irradiating the laser beam onto the patient's eye;
- control means for controlling the irradiation means;
- and
- informing means including a vibrator giving the patient a vibration for informing the patient of at least either a first period of a laser irradiation period or a second period of the laser irradiation period or both.
A laser surgery apparatus for correcting a refractive error of a patient's eye by ablating its corneal tissue with a laser beam comprising:
- an ablation unit which includes a laser light source emitting the laser beam and an irradiation optical system provided with an aperture of which an opening region is changeable and with a projecting lens which projects the aperture on a cornea of the patient's eye;
- an eye fixation target presenting unit which presents an eye fixation target for the patient's eye fixation;
- a computing unit which computes control data based on data on conditions for a surgical operation and divides an operation period into a first period and a second period, the first period during which the patient's eye fixation is important and the second period during which the patient's eye fixation is relatively not important compared to the first period;
- an informing unit which informs the patient of at least either that an operation step is in the first period or that the operation step is in the second period or both;
- and
- a control unit which controls the informing unit in accordance with a change of the opening region of the aperture based on the computed control data.
A laser surgery apparatus for operating on a patient's eye by irradiating a laser beam thereonto comprising:
- an irradiation unit which includes a laser light source emitting the laser beam and an irradiation optical system for irradiating the emitted laser beam onto the patient's eye;
- an eye fixation target presenting unit which presents a fixation target for the patient's eye fixation;
- a computing unit which computes control data based on data on conditions for a surgical operation and divides an operation period into a first period and a second period, the first period during which the patient's eye fixation is important and the second period during which the patient's eye fixation is relatively not important compared to the first period;
- and
- a control unit which controls the eye fixation target presenting unit to inform the patient of at least either that an operation step is in the first period or that the operation step is in the second period or both by changing status of presentation of the fixation target.
