1. A method for determining the optical power of an intraocular lens to be inserted into the eye of a patient, the method comprising:

  • receiving as an input, from an input device, a value that indicates the aphakic refractive power of the patient'"'"'s eye, wherein the input device comprises a wavefront aberrometer aligned with the patient'"'"'s eye to measure the aphakic refractive power;

    determining, with a processor, an estimate of the post-surgical effective lens position (ELP) of the intraocular lens for the patient'"'"'s eye, the estimate being based on the value that indicates the aphakic refractive power of the patient'"'"'s eye; and

    determining an amount of optical power for the intraocular lens to be inserted into the patient'"'"'s eye based on the estimate of the post-surgical ELP of the intraocular lens in the patient'"'"'s eye.
