Abstract: Ophthalmic compositions suitable for use as artificial tears or as vehicles for ophthalmic drugs are disclosed. The compositions contain a combination of three polymers that have a synergistic effect on viscosity.
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.

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.
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.

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.

Abstract: An ophthalmic injection system has a tip segment attachable to and removable from a limited reuse assembly. The tip segment has a dispensing chamber housing, a plunger, a needle, a temperature control device, a thermal sensor, and a first housing at least partially enclosing the dispensing chamber housing, the temperature control device and the plunger. The limited reuse assembly has an actuator with a shaft, a power source for providing power to the actuator, a controller for controlling the actuator, a mechanical linkage interface, and a second housing at least partially enclosing the power source, the controller, and the actuator. The mechanical linkage interface is coupled to the actuator shaft and has a mating surface on one end. The substance is injected after the temperature of the substance is altered.

Abstract: Disclosed are soft, high refractive index, acrylic device materials. The materials comprise di-block or tri-block macromers containing hydrophilic side-chains. The materials have improved glistening resistance.
Abstract: An injection device assembly includes a dispensing chamber housing and a plunger. The dispensing chamber housing is coupled to a needle. The dispensing chamber housing has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for holding a quantity of a substance. A dosage of a substance is cast into the dispensing chamber housing or cast onto a plunger that is inserted into the dispensing chamber housing.
