Abstract
The present invention provides methods, systems and software for scaling optical aberration measurements of optical systems. In one embodiment, the present invention provides a method of reconstructing optical tissues of an eye. The method comprises transmitting an image through the optical tissues of the eye. Aberration data from the transmitted image is measured across the optical tissues of the eye at a first plane. A conversion algorithm is applied to the data, converting it to corrective optical power data that can be used as a basis for constructing a treatment for the eye at a second plane.
