Abstract
In general, the present invention relates to optical elements, which can be modified post-manufacture such that different versions of the element will have different optical properties. In particular, the present invention relates to lenses, such as intraocular lenses, which can be converted into aspheric lenses post-fabrication. Also, the present invention relates to a method for forming aspheric lenses post-fabrication.
