A new and improved method and apparatus for treating glaucoma is described herein. A device for directing aqueous humor from an anterior chamber to Schlemm's canal comprises a seton, and may further comprise a pump operatively connected to the seton. The seton conducts aqueous directly from the anterior chamber to Schlemm's canal so that it can drain directly into the aqueous veins leading to the venous circulation. The seton for lowering intraocular pressure of an associated eye comprises a first tube adapted to be inserted into an associated anterior chamber of the eye; and, two wing tubes extending from the first tube. The two wing tubes are adapted to be inserted into Schlemm's canal. The two wing tubes and the first tube form a substantially continuous passageway, such that aqueous humor flows from the anterior chamber into Schlemm's canal through the substantially continuous passageway.

A method for enhancing aqueous outflow and thereby lowering intraocular pressure is disclosed. The method comprises vasodilating aqueous veins by dilating or relaxing the smooth muscle of an aqueous cavity. In one embodiment, the step of dilating or relaxing the smooth muscle of the aqueous cavity is accomplished by slowly releasing loaded smooth muscle relaxing drug at an effective dose over time. In another embodiment, the step of dilating the smooth muscle of the aqueous cavity is accomplished by introducing a smooth muscle drug through an implant.

Methods, devices and systems for draining fluid from the eye and / or for reducing intraocular pressure. A passageway (e.g., an opening, puncture or incision) is formed in the lamina cribosa or elsewhere to facilitate flow of fluid from the posterior chamber of the eye to either a) a subdural location within the optic nerve or b) a location within the subarachnoid space adjacent to the optic nerve. Fluid from the posterior chamber then drains into the optic nerve or directly into the subarachnoid space, where it becomes mixed with cerebrospinal fluid. In some cases, a tubular member (e.g., a shunt or stent) may be implanted in the passageway. A particular shunt device and shunt-introducer system is provided for such purpose. A vitrectomy or vitreous liquefaction procedure may be performed to remove some or all of the vitreous body, thereby facilitating creation of the passageway and / or placement of the tubular member as well as establishing a route for subsequent drainage of aqueous humor from the anterior chamber, though the posterior chamber and outwardly though the passageway where it becomes mixed with cerebrospinal fluid.

An apparatus and method for treating presbyopia and lowering intraocular pressure employing an intra-scleral implant into an elongated cavity oriented in the radial direction of the eye. The implant has a planar portion with a longitudinal axis running therethrough and a pair of extension portions extending a distance away from said planar portion and said longitudinal axis. The implant is implanted in an incision in four quadrants of the sclera. The incisions are shaped similar to the implants. The projecting extensions into side projections of the incisions, provide an anchor to maintain the implant in the sclera.

An eye mounted device configured to actively evacuate fluid from the anterior chamber of the eye to an exterior region or the sclera of the eye. The device employs a miniature pump powered by a photovoltaic cell which is mounted in the clear corneal tissue and which may be curved in the same shape as the eye. One or a combination of pressure sensors and timers determine the duration the device evacuates fluid from the user's eye.
