Disclosed are devices, methods and systems for treatment of eye disease, including open angle glaucoma and narrow angle glaucoma. Implants are described herein that create a directed flow field, such as between the anterior chamber and either the supraciliary space or suprachoroidal space. In addition, the implant can include a variety of features, including extruded features, such as rings and pegs, which can assist in preventing ocular tissue from collapsing onto the implant and occluding fluid pathways.

Apparatuses and methods for the treatment of glaucoma are provided. The instrument uses either cauterization, a laser to ablate, sonic or ultrasonic energy to emulsify, or mechanical cutting of a portion of the trabecular meshwork. The instrument may also be provided with irrigation, aspiration, and a footplate. The footplate is used to enter Schlemm's canal, serves as a guide, and also protects Schlemm's canal.

A glaucoma treatment device applies electrolysis into an eye has a plurality of electrodes connected to a voltage source, and a controller coupled to a pressure sensor. The electrodes apply an electric field within an eye, and the controller regulates the delivery of current to the electrodes based on intraocular pressure measurements from the pressure sensor. The device has an enclosure for the pressure sensor, controller, and voltage source. The voltage source can recharge via an external source and the controller can accept adjustments remotely. The device also operates as a component in a method to convert aqueous humor into gas. The method utilizes electrolysis to reduce the volume of fluid in the anterior chamber of an eye. The method modulates electric current during usage of the invention. The method and device combine to reduce intraocular pressure within an eye thus lessening the progression of glaucoma.

An ocular implant comprising a shunt and a fluid absorbing conduit for reducing intraocular pressure, and optionally comprising a biodegradable ring.

Devices and methods for the ab interno delivery of two or more fluid compositions into Schlemm's canal through a single insertion point in the eye with minimal trauma. The hand-held delivery device includes a handle coupled to an elongated shaft that terminates in a self-trephinating tip through which one or more cannulae are slidably disposed and can be extended or retracted therethrough. The handle further defines a chamber for receiving one or more cartridges each containing at least one fluid composition. Each cartridge is fluidly connected to a respective cannula such that sequential actuation of each cartridge causes dispensation of the fluid compositions at the site for delivery without having to repeatedly enter the target site multiple times. Ab interno methods for localized delivery of a fluid composition into Schlemm's canal are further described.

Systems and methods for delivering multiple ocular implants to reduce intraocular pressure are disclosed. The ocular implants can be implanted at multiple sites within a single human eye without requiring removal of the delivery apparatus from the eye. A system for delivering multiple ocular implants can include at least two implants preloaded within a delivery device and configured to be implanted within the eye, a metering device configured to transfer energy to the implants for delivery at selected locations within the eye, wherein the metering device is configured to meter a variable amount of energy for each implant delivery event in the eye. The system can further include an injector mechanism configured to serially engage and drive each of the implants.

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.

An ophthalmic surgical system includes a cannula having a receptacle. The receptacle includes a valve and a first lip extending inwardly and defining at least a portion of a chamber in the receptacle. The ophthalmic surgical system also includes a surgical instrument having a second lip that is sized and shaped to engage with the first lip of the cannula to couple the surgical instrument to the cannula.

The present invention provides for a deformable, insertable device for relieving intraocular pressure comprising a body portion composed of a biocompatible porous material with pores throughout to permit drainage of fluid from the anterior chamber to the scleral tissue without collapse of the anterior chamber. The invention also includes a method for inserting the device into the eye and for using ultrasound intraoperatively to determine the position of surgical tools and devices within the sclera. The invention also includes a device excising sclera in an eye to create a chamber for insertion of the insertable device into the eye.

Glaucoma can be treated by implanting an intraocular shunt into an eye. The eye has an anterior chamber and sclera. A shunt can be placed into the eye to establish fluid communication from the anterior chamber of the eye through the sclera, and a pharmaceutical or biological agent can be administered to the eye.
