  • Publication number: 20110071454
    Abstract: A glaucoma drainage device has a tube shunting the anterior chamber to a drainage location. A power generator has a rotor coupled to a micro-generator. The power generator is configured to generate energy from aqueous flowing through the tube. The force required to drive the rotor can be controlled to control the flow of aqueous through the tube. Alternatively, energy generated by the power generator is stored in a power source that powers an active valve, a pressure sensor, or telemetry.

  • Publication number: 20110071458
    Abstract: A glaucoma drainage device may comprise a main drainage tube with a first end configured to be located in an anterior chamber of an eye and a second end configured to be located in a drainage location. A bypass drainage tube is fluidly coupled to and in parallel with the main drainage tube. A pump is in communication with the bypass drainage tube. The pump comprises a first driver and a first flexible membrane enclosing a first chamber. A first check valve is located upstream of the pump, and a second check valve is located downstream of the pump. An active valve is located upstream of the first check valve. The active valve comprises a second driver and a second flexible membrane enclosing a second chamber. A third check valve is located between the active valve and the second end of the main drainage tube. A volume of the first chamber is changed to pump fluid from the anterior chamber to the drainage location.

  • Publication number: 20110071459
    Abstract: A glaucoma drainage device has an active valve configured to be located between an anterior chamber of an eye and a drainage location, a power source coupled to the active valve, and a controller coupled to the power source. A first pressure sensor is located in fluid communication with the anterior chamber, a second pressure sensor is located in the drainage location, and a third pressure sensor located remotely from the first and second pressure sensors. The controller reads the first, second, and third pressure sensors once during a period of time and adjusts the active valve to control intraocular pressure.

  • Publication number: 20110059039
    Abstract: The use of poly(oxyethylene)-poly(oxybutylene) block copolymers in pharmaceutical compositions useful for modifying the surfaces of contact lenses and other medical devices is disclosed. The present invention is based in-part on a discovery that this class of compounds is particularly efficient in wetting hydrophobic surfaces, such as the surfaces of silicone hydrogel contact lenses and other types of ophthalmic lenses. Such compounds are also useful for cleaning purposes. The use of the compounds as surfactants in various types of compositions for treating contact lenses therefore represents a preferred embodiment of the present invention.
