  • Therapeutic device for pain management and vision
    Patent number: 10555804
    Abstract: A therapeutic lens for the treatment of an epithelial defect comprises a layer of therapeutic material disposed over the stroma and/or Bowman's membrane to inhibit water flow from the tear liquid to the stroma and/or Bowman's membrane, such that corneal deturgescence can be restored to decrease corneal swelling and light scattering. The layer may cover and protect nerve fibers to decrease pain. The layer may comprise an index of refraction to inhibit light scatter from an anterior surface of the stroma and/or Bowman's membrane. The lens may comprise a curved anterior surface that provides functional vision for the patient when the epithelium regenerates. The layer of therapeutic material can be positioned on the eye in many ways, for example with a spray that is cured to adhere the layer to the exposed surface of the stroma and/or Bowman's membrane.

  • Method of removing organic contaminants from air and water with organophilic, quaternary phosphonium ion-exchanged smectite clays
    Patent number: 5635075
    Abstract: An quaternary phosphonium ion-exchanged clay and method of removing organic contaminants from air and/or water, by contacting the contaminants in the air or water with a quaternary phosphonium organo-clay. The clay is prepared by ion-exchange of an ion-exchangeable clay with (a) tetra-short chain alkyl (C.sub.1 -C.sub.4) quaternary phosphonium ion or (b) a di- or tri-short chain alkyl (C.sub.1 -C.sub.4) quaternary phosphonium ion having 1 or 2 mono-substituted or unsubstituted cycloakyl moieties, or one or two alkaryl moieties for removing air-laden and water-laden organic contaminants. The new organo-clays and methods are particularly adapted for removal of aromatic petroleum-based contaminants from water, such as benzene; alkylbenzenes, such as toluene; xylenes (o-, m- and p-isomers); and chlorinated 1 and 2 carbon compounds, such as CCl.sub.4.

  • Anterior segment drug delivery
    Patent number: 10004636
    Abstract: A therapeutic system comprises an ocular insert placed on a region outside an optical zone of an eye. The ocular insert comprises two structures: a first skeletal structure and a second cushioning structure. The first structure functions as a skeletal frame which maintains positioning of the implant along the anterior portion of the eye and provides support to the second, cushioning structure. This first structure maintains the attachment of the therapeutic system to the anterior portion of the eye for at least thirty days. In some embodiments the first structure remains a constant size and shape, e.g. a ring shape, a ring with haptics, or a curvilinear ring that is confined to and restrainingly engages the inferior and superior conjunctival fornices so as to retain the implant within the tear fluid and/or against the tissues of the eye.

  • Method and system in a wireless communications network for providing restricted user termination areas based on originator location
    Patent number: 6256503
    Abstract: A method and system in a wireless communications network are provided for restricting communication transactions based on the geographic location of originators and terminators within the wireless communications network. First, a communications transaction is initiated. In response to an initiation of the communications transaction, a geographic location of an originator of the communications transaction is determined. In response to determining the geographic location of the originator, a geographic location of a terminator of the communications transaction is determined. The geographic location of the originator is thereafter automatically compared to the geographic location of the terminator. The communications transaction is completed based upon a selected proximity of the geographic location of the originator to the geographic location of the terminator.
