Patent ID: 8540370

Claim:
A method of selecting an IOL to be implanted in the eye of a subject comprising: a) determining an axial eye length and a pupil size at a desired light level and determining at least one of a desired postoperative refraction and a desired postoperative spherical aberration; b) determining an aspheric representation of a corneal curvature; c) selecting an IOL with predetermined power and asphericity, and determining a location of the lens haptic plane (LHP); d) employing the results of previous sections to establish an eye model for the eye of the subject, the eye model including the axial eye length, the pupil size, the aspheric representation of the corneal curvature, and the LHP; e) computing with a ray tracing routine and the axial eye length, the pupil size, the aspheric representation of the corneal curvature, and the LHP of said eye model, an expected at least one of a postoperative refraction and postoperative spherical aberration; f) in the case that the at least one of the expected postoperative refraction and postoperative spherical aberration is not within a predetermined criteria, selecting another IOL with different power and/or asphericity and repeating steps d) and e) until the at least one of the expected postoperative refraction and postoperative spherical aberrations is within the at least one of the desired postoperative refraction and desired postoperative spherical aberration; and g) selecting, for implantation, an implantable IOL of the nearest power and asphericity available.
