Patent ID: 7971997

Claim:
An intraocular lens selection apparatus for selecting an intraocular lens (IOL) to be implanted into an examinee's eye, the apparatus comprising: storing means which stores information on a plurality of IOL models and IOL calculation formulae, the information including a model name, an A constant, and spherical aberration; first input means which inputs information on any one of a wavefront aberration and an eye refractive power of the examinee's eye, and corneal information including a three-dimensional shape of a cornea of the examinee's eye; second input means which inputs information necessary to determine an IOL diopter including an ocular axial length of the examinee's eye; setting means which sets, as target values, a residual wavefront aberration and an eye refractive power of the examinee's eye after the IOL is implanted; calculation means which (1) obtains a corneal wavefront aberration of the examinee's eye with a corneal aberration assumed to be zero based on the three-dimensional shape of the cornea, and (2) obtains one of the plurality of IOL models and a refractive power which are closest to the set target values based on the obtained corneal wavefront aberration, the information stored in the storing means, and the information input by the first and second input means; display means; and control means which controls the display means to display a result obtained by the calculation means.
