Abstract
A lens for placement in a human eye, such as intraocular lens, has at least some of its optical properties formed with a laser. The laser forms modified loci in the lens when the modified loci have a different refractive index than the refractive index of the material before modification. Different patterns of modified loci can provide selected dioptic power, toric adjustment, and/or aspheric adjustment provided. Preferably both the anterior and posterior surfaces of the lens are planar for ease of placement in the human eye.
