Abstract
In one aspect, the present invention provides methods for custom fabrication of IOLs. In some embodiments, such methods call for measuring one or more aberrations of a patient's eye, and determining the profile of at least one surface of an IOL that would ameliorate, and control those aberrations. The surface profile can then be imparted to a surface of a starting lens (or a lens blank) via ablation, e.g., by utilizing an excimer laser beam. In some other embodiments, the measured aberrations can be utilized to determine the profile of at least one surface of a wafer mold. A wafer mold having that surface profile can then be fabricated, e.g., by ablating a slab or an existing wafer of appropriate material, and the mold can be used to fabricate an IOL suitable for implantation in the patient's eye.
