PROBLEM TO BE SOLVED: To provide a system for forming and modifying a lens, and also to provide a lens formed by the system.SOLUTION: 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 a modified locus in the lens when the modified locus has a different refractive index than the refractive index of the material before modification. Different patterns of a modified locus can provide selected dioptric 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. |
