  • Method of decellularizing porcine cornea
    Patent number: 8313893
    Abstract: Disclosed is a method for processing porcine cornea using an aqueous NaCl solution and an aqueous trypsin/EDTA solution to decellularize enucleated porcine cornea. The porcine cornea processed by the method causes neither inflammation nor immune rejection. The porcine corneal stroma decellularized by the method can be recellularized together with host keratocytes after transplantation.
    Type: Grant

  • OPHTHALMIC APPLICATOR FOR TREATMENT OF PTERYGIUM OR GLAUCOMA USING 32P ALONE OR IN COMBINATION WITH 103Pd
    Publication number: 20080300444
    Abstract: Disclosed is an ophthalmic applicator for the treatment of pterygium or or glaucoma using a radioisotope. It comprises a source volume for containing the radioisotope therein; a filter volume for controlling a radiation dose emitted from the radioisotope; and an encapsulation volume for encompassing the source volume and the filter volume, wherein the radioisotope is pure 32P or a combination of 32P and 103Pd. Ensuring the formation of more ideal dose distributions than do the conventional 90Sr ophthalmic applicators, as described hitherto, the ophthalmic applicator for the treatment of pterygium or glaucoma using 32P or a combination of 32P and 103Pd can promise both high therapeutic effects on pterygium or glaucoma and high safety effects on the eye lens. Further, 32P and 103Pd are easier to produce and treat than is 90Sr, thereby allowing the radiotherapy to be useful.

  • Artificial cornea and implantation thereof
    Patent number: 6254637
    Abstract: An artificial cornea capable of preventing a separation thereof from an eyeball of the patient during an implant operation thereof while avoiding post-operative complications at the interface between the artificial cornea and the patient's cornea, such as erosive tissue necrosis (melting), leakage of aqueous humor, infection, extrusion of the implant, and intraocular inflammation.
