Abstract:
1. An ophthalmic surgery system comprising an ophthalmic measurement apparatus and a refractive correction surgery apparatus, wherein the ophthalmic measurement apparatus comprises: optometry means having a measurement optical system for measuring a patient's eye to obtain measurement data on the eye necessary for refractive correction; first alignment means for aligning an optical axis of the measurement optical system with a predetermined position of the eye; first photographing means for photographing an anterior segment of the eye under a condition that the optical axis of the measurement optical system is aligned with the predetermined position of the eye by the first alignment means; first identification code acquiring means for extracting an iris pattern, which is inherently unique to the eye, by processing a first image of the eye anterior segment photographed by the first photographing means during the measurement of the eye, and obtaining a first identification code based on the extracted iris pattern; storage means for storing the obtained measurement data or surgical data on the eye for the refractive correction generated based on the obtained measurement data in association with the obtained first identification code, and output means for outputting the measurement data or the surgical data along with the associated first identification code which are stored in the storage means, and the refractive correction surgery apparatus comprises: surgery means for performing surgery for the refractive correction on the eye by irradiating a cornea of the eye with a laser beam for ablation, the surgery means having an irradiation optical system for irradiating the laser beam onto the cornea; second alignment means for aligning an optical axis of the irradiation optical system with a predetermined position of the eye; second photographing means for photographing the eye anterior segment under a condition that the optical axis of the irradiation optical system is aligned with the predetermined position of the eye by the second alignment means; second identification code acquiring means for extracting the iris pattern by processing a second image of the eye anterior segment photographed by the second photographing means before the irradiation of the laser beam, and obtaining a second identification code based on the extracted iris pattern; comparison means for comparing the first identification code received from the ophthalmic measurement apparatus and the obtained second identification code to judge whether the first identification code and the second identification code match; and permission means for permitting the surgery to be performed by the surgery means based on the surgical data received from the ophthalmic measurement apparatus, or permitting the surgical data to be generated based on the measurement data received from the ophthalmic measurement apparatus when the comparison means judges that the first identification code and the second identification code match.
