Generalized presbyopic correction methodology

An adaptive optics phoropter is aligned with a Badal optometer and an adjustable aperture component to subjectively determine an optimal vision correction as a power profile for an ophthalmic lens or ablating a cornea. The optimal power profile is preferably determined in an iterative process by adj...

description	An adaptive optics phoropter is aligned with a Badal optometer and an adjustable aperture component to subjectively determine an optimal vision correction as a power profile for an ophthalmic lens or ablating a cornea. The optimal power profile is preferably determined in an iterative process by adjusting the vergence of the Badal optometer and aperture size of the adjustable aperture component for power profiles with presbyopic power zones having different amplitudes, shapes, widths, and/or de-centering. Also included is a method of recursively computing a refractive surface with a regular presbyopic power zone (e.g., according to the optimal power profile) and adding it onto an underlying irregular Zernike-basis-set aberration-corrected surface in a linear fashion for fabricating an ophthalmic lens.
