  • 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.

  • Publication number: 20180333296
    Abstract: Disclosed herein are drug delivery implants configured to be implanted into the eye of a subject and serve as intraocular drug depots. The implants reside in an intraocular target site until activation, at which time the implants release the drug (or drugs) housed within the implant in a controlled release fashion.

  • Publication number: 20180161205
    Abstract: Implants and methods for treating ocular disorders are provided. One method involves introducing an implant into an anterior chamber of an eye. The implant is implanted into eye tissue adjacent the anterior chamber such that a proximal end of the implant resides in the anterior chamber following implantation. A therapeutic agent is eluted from the implant into the eye. Desirably, the release of the therapeutic agent from the implant is controlled. The controlled release of the therapeutic agent can be at a chosen rate and/or for a selected duration which can be episodic or periodic. The therapeutic agent can be an antiproliferative agent, an anti-inflammatory drug, or a compound for treating glaucoma or ocular hypertension.

  • Publication number: 20180085065
    Abstract: An implantable intraocular physiological sensor for measuring a physiological characteristic, such as intraocular pressure. The implantable intraocular physiological sensor may include a tubular main body configured to house one or more electrical components. The implantable intraocular physiological sensor may also include a sensor cap configured to be inserted into a first end of the tubular main body with a moisture barrier seal. The implantable intraocular physiological sensor may wirelessly transmit measurements to an external device.

  • Publication number: 20180070817
    Abstract: A gonioscopic attachment can attach to a gonioscope and can include atraumatic retention elements that are configured to engage an eye to retain the gonioscope relative to the eye. The gonioscopic attachment can be configured to position the gonioscope so that at least a portion of the concave distal surface of the gonioscopic optical element is spaced apart from the eye, and/or so that the curvature of the distal surface is angularly offset from the curvature of the eye. The gonioscope can include a fixation point configured to be visible to the subject when the gonioscope is positioned on the eye. In some embodiments, the retention elements can be incorporated directly into the gonioscope. A coupling mechanism can couple the gonioscope to a lid speculum. The gonioscope can include a light pipe, which can be configured to directly light into the eye.

  • Patent number: 9592151
    Abstract: Delivery devices, systems and methods are provided for inserting an implant into an eye. The delivery or inserter devices or systems can be used to dispose or implant an ocular stent or implant, such as a shunt, in communication with the suprachoroidal space, uveal scleral outflow pathway, uveoscleral outflow path or supraciliary space of the eye. The implant can drain fluid from an anterior chamber of the eye to a physiologic outflow path of the eye, such as, the suprachoroidal space, uveal scleral outflow pathway, uveoscleral outflow path or supraciliary space. Alternatively, or in addition, the implant can elute a drug or therapeutic agent. The delivery or inserter devices or systems can be used in conjunction with other ocular surgery, for example, but not limited to, cataract surgery through a preformed corneal incision, or independently with the inserter configured to make a corneal incision.
