  • Patent number: 7682020
    Abstract: The present invention provides an orthokeratological contact lens to be worn on a patient's cornea and methods for prescribing the same. The contact lens comprises a parabolic lens having an inner surface configured to face an epithelium of the patient's cornea, wherein the parabolic lens is adapted to reshape the cornea by way of epithelium and/or stromal tissue growth. In a pre-treatment configuration, an outer surface of the epithelium does not conform to the contours of the inner surface of the parabolic lens such that there exits a gap comprising a hypertrophy volume that is disposed between the epithelium and the parabolic lens.
