  • Patent number: 6537545
    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.

  • Publication number: 20020119141
    Abstract: The invention disclosed herein relates to biochemical methods for the elimination of corneal collagen fiber disorganization to improve vision. Disorganization of corneal collagen fibers is seen in corneal scars, corneal opacification and corneal haze. In addition, the invention relates to biochemical methods for the elimination of corneal collagen fiber disorganization resulting from accidental traumatic injury to the cornea and from refractive surgery for such as radial keratotomy (RK), photorefractive keratectomy (PRK), and laser in situ keratomileusis (LASIK) so as to improve visual acuity and quality of vision.

  • Patent number: 6338847
    Abstract: Compositions and methods to disinfect contact lenses are disclosed. In one embodiment, the present composition comprises a cellulose decomposing enzyme component, e.g., lysozyme, and a hydrogen peroxide destroying component. The composition is structured so that the cellulose decomposing enzyme component is released in a liquid medium containing hydrogen peroxide before the hydrogen peroxide destroying component is released in the liquid medium. Such cellulose decomposing enzyme component is preferably effective to render hydrogen peroxide-resistant microorganisms, e.g., acanthamoeba cysts, which may contaminate the lens more susceptible to being killed by hydrogen peroxide.

  • Patent number: 6193963
    Abstract: The invention is based on the discovery of methods for purification of an acid active hyaluronidase found in human plasma (hpHAse), including both biochemical and immunoaffinity purification methods. The method of immunoaffinity purification of the invention is based on the discovery of a method for identifying antibodies that specifically bind native hpHAse (anti-native hpHAse antibodies), and anti-native hpHAse antibodies identified by this screening method. The invention also features an assay for sensitive detection of HAse activity using biotinylated hyaluronic acid (bHA). Purification and characterization of hpHAse lead to the inventors' additional discovery that hpHAse is encoded by the LuCa-1 gene, which gene is present in the human chromosome at 3p21.3, a region associated with tumor suppression. The invention additionally features methods of treating tumor-bearing patients by administration of hpHAse and/or transformation of cells with hpHAse-encoding DNA.
