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 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.
