Claim:
1. A method of selecting an intraocular lens (IOL) configured to be implanted in a patient's eye, the method comprising: obtaining at least one characteristic of the patient's eye using a diagnostic instrument; and selecting an IOL having an optical power that reduces optical errors in an image produced at a peripheral retinal location of the patient's eye disposed at a distance from the fovea, wherein the IOL is configured to produce an image by focusing light incident on the patient's eye at an oblique angle with respect to an optical axis intersecting the patient's eye at the peripheral retinal location, wherein a modulation transfer function (MTF) of the IOL at one or more spatial frequencies for light incident on the IOL at the oblique angle having a value between 1 and 25 degrees with respect to the optical axis at the peripheral retinal location is greater than a modulation transfer function (MTF) of the IOL at one or more spatial frequencies for light incident on the optic at an angle less than 1 degree with respect to the optical axis at the fovea, wherein the optical power of the IOL is based on the obtained characteristic, and wherein a first surface of the IOL is a Zernike surface.
