Abstract
“Universal improvement” of vision is achieved by effectively changing the shape of the anterior refracting surface of the cornea to an ideal “turtleback” shape, on which is imposed the necessary curvature adjustment to achieve correction of distance vision. In accordance with one embodiment, the cornea is actually formed to the turtleback shape through corneal surgery, preferably laser ablation surgery. In accordance with a second embodiment, a contact lens with the desired distance corrected ideal turtleback shape on its anterior surface is positioned over the cornea.

1-24. (canceled)
In a method for improving or planning the improvement of the vision of an eye, the steps of, on a surface model of the cornea of the eye, determining points of focus for different locations on the surface model and modifying the model so as to shift points of focus to a predetermined location relative to predefined reference axis, without forcing them to a common point, the modified model representing a desired restructuring of the cornea.
