A process for producing silicone intraocular lenses (IOLs) capable of absorbing blue light. Intraocular lenses so produced block blue light from reaching the retina of an eye implanted with the IOL. By blocking blue light from reaching the retina, the IOL thereby prevents potential damage to the retina.

Novel azo-based reactive yellow dyes and a process for manufacturing and using ocular devices having blue light absorption properties. Intraocular lenses so produced block blue light from reaching the retina of an eye implanted with the IOL. By blocking blue light from reaching the retina, the IOL thereby prevents potential damage to the retina.

A process for producing intraocular lenses (IOLs) capable of absorbing blue light and ultraviolet light using photo curing. Intraocular lenses so produced block blue light and ultraviolet light from reaching the retina of an eye implanted with the IOL. By blocking blue light and ultraviolet light from reaching the retina, the IOL thereby prevents potential damage to the retina.

A surgical blade is disclosed for use with a surgical tool for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The surgical blade comprises a rotatable support arm capable of being rotated by the surgical tool and a detachable curved cutting blade for making incisions in the sclera of an eye. The surgical tool causes the curved cutting blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the curved cutting blade is detached from the rotatable support arm. The curved cutting blade is then removed from the incision by pulling the curved cutting blade forward out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.

A three-coil electromagnetic induction power transfer system is disclosed for epiretinal prostheses and other implants. A third, buffer coil is disposed between an external transmitting coil and a receiver coil buried within the body to improve efficiency and robustness to misalignments. One or more of the coils can be manufactured using micromechanical machining techniques to lay out conductors in a ribbon of biocompatible insulator, folding lengths of the insulated conductor traces longitudinally over one another, and then spiraling them into a ring. The traces change axial position in the ring by shifting across fold lines. One or more U-shaped sections on the traces can be folded so that adjacent traces can project opposite one another, lengthening the resulting ribbon that can be wound into a coil.

The invention relates to an artificial eye implant, especially as a substitute for an eye lens or a vitreous body of a human or animal eye consisting of a hollow body, wherein the hollow body is made of a biocompatible, flexible and extensible material and is able to be filled with a medium. The present invention further relates to methods of positioning an artificial eye implant within the eye of a human or an animal generally comprising the steps of: preparing an eye to receive an intraocular artificial eye implant wherein said implant consists of a hollow body made of a biocompatible, flexible and extensible material, said hollow body is able to be filled with a medium; inserting said intraocular eye implant into said eye via a small cut in said eye; positioning said implant in the non-filled state in the capsule bag or the posterior orbit of the eye; filling said implant with said medium; and closing the eye where said implant was inserted.

Apparatus is provided for expanding a Schlemm's canal of an eye of a subject, the apparatus including an introducer having a lumen and a plurality of expandable porous structures sized and shaped to be disposed with the lumen. The expandable porous structures are configured (a) to be inserted into the Schlemm's canal at discrete locations around the canal, (b) to be inserted into the Schlemm's canal while in a collapsed form, and (c) to expand while inside the Schlemm's canal.

An apparatus for safely retaining an eye implant lens for transport and access for inspection and use in which a holding apparatus has a chamber for holding a lens. In one embodiment the chamber has aligned transparent portions and a lens can be placed in alignment with the transparent portions to enable inspection. Also, a system including the apparatus and a bottle assembly that will hold the apparatus in the bottle. A method for holding an eye implant lens in which a lens is placed in the apparatus which can then be placed in a bottle assembly.

Systems and methods for delivering a plurality of ocular implants to reduce intraocular pressure are disclosed. The ocular implant can be implanted at multiple sites within a single human eye without the need to remove the delivery device from the eye. A system for delivering multiple ocular implants may include multiple implants, an outer housing, and an introducer assembly. The outer housing can provide access to the implant segmentation actuator and the implant delivery actuator. The introducer assembly may include a self-retracting introducer portion. The delivery device may include an infinite activation mechanism / section and / or a manual dividing mechanism / section.

A visual prosthesis in the form of a retinal implant, which is distinguished by the least possible space requirement inside the eye, is achieved by a visual prosthesis having an intraocular implant and an extraocular implant, which supplies the intraocular implant with energy and controls it. Virtually all the electronic components, which do not necessarily need to be accommodated with the intraocular implant inside the eye, can be arranged outside the eyeball, for example on the sclera. In this way, the space requirement of the stimulation system inside the eye is reduced and the operative intervention for implanting the stimulation system inside the eye is kept as small as possible. A bidirectional inductive interface between an extracorporeal part of the visual prosthesis and an intracorporeal part, including the intraocular and extraocular implants, via which a current supply and bidirectional data transmission can be carried out is provided.

The present disclosure discloses an apparatus to be implanted in eyes, including: a configuration memory used for storing signal parameter configuration; a signal generator connected to the configuration memory and used for generating stimulating signals according to the signal parameter configuration in the configuration memory; electrodes connected to the signal generator and contact with outer surface of eye ball after implanted; a communication assembly connected to the configuration memory and used for receiving the signal parameter configuration, storing the received signal parameter configuration in the configuration memory; and a power supply connected to the configuration memory, signal generator and communication assembly, used for providing power. An update system for the apparatus is also disclosed. By using the above apparatus and update system, when it needs to change waveform parameter of stimulating signals, there is no need to take the apparatus out, reducing harm on human body and improving safety.
