Abstract
Continuous, aspheric optical molds for reshaping the surface of the cornea having an inner concave surface matched to the topography of the cornea. The curvatures of the molds are modified from a curve matched to a patient's corneal topography to include a flattened pressure zone applying relative pressure and thereby displacing underlying corneal tissue, a steepened relief zone raised away from the surface of the cornea to receive displaced corneal tissue, and a flattened anchor zone to control and direct movement of displaced corneal tissue into the relief zones.
