Abstract
The present invention provides methods for measuring corneal characteristics and distortions to determine one or more appropriate designs for one or more corrective lenses used to reshape the cornea of an eye. The method includes measuring and/or mapping the topology of the cornea, identifying a desired new shape for the cornea, comparing the current shape of the cornea to the desired shape, and configuring one or more corrective lenses to apply force to the cornea to change its shape. The process of measuring and/or mapping, comparing, and configuring may be repeated until the cornea takes on the desired shape.
