  • Publication number: 20190053704
    Abstract: An implantable intraocular physiological sensor for measuring intraocular pressure, glucose concentration in the aqueous humor, and other physiological characteristics. The implantable intraocular physiological sensor may be at least partially powered by a fuel cell, such as an electrochemical glucose fuel cell. The implantable intraocular physiological sensor may wirelessly transmit measurements to an external device. In addition, the implantable intraocular physiological sensor may incorporate aqueous drainage and/or drug delivery features.

  • Patent number: 10206813
    Abstract: Disclosed herein are drug delivery devices and methods for the treatment of ocular disorders requiring targeted and controlled administration of a drug to an interior portion of the eye for reduction or prevention of symptoms of the disorder. The devices are capable of controlled release of one or more drugs and may also include structures which allow for treatment of increased intraocular pressure by permitting aqueous humor to flow out of the anterior chamber of the eye through the device.

  • Publication number: 20190021991
    Abstract: Disclosed herein are drug delivery devices and methods for the treatment of ocular disorders requiring targeted and controlled administration of a drug to an interior portion of the eye for reduction or prevention of symptoms of the disorder. In several embodiments, the devices are configured to release a pro-drug form of a drug into a target tissue site, wherein the pro-drug is converted to an active drug that yields a therapeutic effect. The use of the device and pro-drug form advantageously, in several embodiments, provide a stable drug composition that can yield a therapeutic effect over an extended time period.
