A lens for placement in a human eye, such as intraocular lens, has at leastsome of its optical properties formedwith a laser. The laser forms modified loci in the lens when the modified locihave a different refractive index than the refractiveindex of the material before modification. Different patterns of modified locican provide selected dioptic power, toric adjustment,and/or aspheric adjustment provided. Preferably both the anterior andposterior surfaces of the lens are planar for ease of placementin the human eye.
