  • Use of corneal hardening agents in enzymeorthokeratology
    Publication number: 20030175259
    Abstract: An Enzyme Orthokeratology method is provided for correcting refractive errors in the eye of a subject mammal. Accelerating reshaping of the cornea is accomplished by administering a corneal hardening amount of a corneal hardening agent to the eye of the subject. Reformation is accomplished under the influence of a rigid contact lens or a series of lenses having a concave curvature that will correct a refractive error. The cornea rapidly reshapes its convex curvature to the concave curvature of the contact lens, rendering the eye emmetropic. The cornea is permitted to “harden” to retain the new emmetropic shape. After “hardening” has occurred, the lens rendering the eye emmetropic is removed.
