  • Publication number: 20180193133
    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.

  • Publication number: 20180177634
    Abstract: A comfortable insert comprises a retention structure sized for placement under the eyelids and along at least a portion of conjunctival sac of the upper and lower lids of the eye. The retention structure resists deflection when placed in the conjunctival sac of the eye and to guide the insert along the sac when the eye moves. The retention structure can be configured in many ways to provide the resistance to deflection and may comprise a hoop strength so as to urge the retention structure outward and inhibit movement of the retention structure toward the cornea. The insert may move rotationally with deflection along the conjunctival sac, and may comprise a retention structure having a cross sectional dimension sized to fit within folds of the conjunctiva. The insert may comprise a release mechanism and therapeutic agent to release therapeutic amounts of the therapeutic agent for an extended time.

  • 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.

    Abstract: Described herein are devices and methods for treating eye conditions. Described is an ocular implant including an elongate member having an internal lumen forming a flow pathway, at least one inflow port communicating with the flow pathway, and at least one outflow port communicating with the flow pathway. The elongate member is adapted to be positioned in the eye such that at least one inflow port communicates with the anterior chamber, at least one outflow port communicates with the suprachoroidal space to provide a fluid pathway between the anterior chamber and the suprachoroidal space when the elongate member is implanted in the eye. The elongate member has a wall material imparting a stiffness to the elongate member. The stiffness is selected such that after implantation the elongate member deforms eye tissue surrounding the suprachoroidal space forming a tented volume.
