A deformable, insertable device for relieving intraocular pressure comprising a body portion composed of a biocompatible porous material, said body portion comprising a first end portion and a second end portion, said body portion defining pores therethrough, said pores being of such size and quantity as to permit drainage of fluid from the anterior chamber to the scleral tissue without collapse of the anterior chamber; and

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.

The invention discloses an artificial lens with an iris diaphragm, comprising an optical zone (1) which is transparent at the center, the iris diaphragm (2) surrounding the optical zone (1) and a loop (3); the artificial lens is in an integrated style and is composed of an entire block of material, the material is selected from foldable materials such as hydrophobic acrylic ester, hydrophilic acrylic ester, silica gel, etc. The artificial lens with the iris diaphragm of the invention has soft texture, can be filled or implanted in the eyes by a small incision after being folded; in addition, the artificial lens has high refractive index, thin lens, small incision and slow formation of after cataract and can slowly restore in 2-30 seconds after being implanted, thus cyst membrane is not easy to be damaged; moreover, the artificial lens has the advantages of little astigmia developed in post-operation, quick healing, fast recovery of visual performance and little postoperative treatment; a brown iris, which is the natural color iris of Chinese, can be adopted, and the eye implanted with such an artificial lens looks more natural.

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.

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.

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.

The present invention relates to preparation process of cross-linked sodium hyaluronate gel as eye implant. The process of preparing the cross-linked sodium hyaluronate gel includes the following steps: pouring the reactant liquid comprising sodium hyaluronate, hydrazide compound, carbodiimide as carboxyl group activator and proper buffer into the gap between two plates to form gel in certain thickness; purifying; cutting; packing and sterilizing. The cross-linked sodium hyaluronate gel is used as eye implant, especially for the non-penetrating glaucoma treating operation, to prevent adhesion of the aqueous humor filtering passage, raise the filtering effect and control the post-operational intraocular pressure.

An apparatus for supplying energy to and/or communicating with an eye implant by means of illumination radiation is provided, wherein the apparatus (1) comprises a positioning unit (3), which sets anillumination position of the eye of a user, an optical input interface, by means of which the illumination radiation (10) is suppliable to the apparatus (1), and an illumination optical unit (7), wherein the illumination optical unit (7) focuses the supplied illumination radiation (10) in such a way that a focus (16) with a lateral extent of at least 0.1 mm in air is present and such that, when the eye of the user is in the set illumination position, the illumination radiation (10) enters into the eye (14) as a convergent beam such that the focus (16) lies within the eye (14).

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.

The invention belongs to the field of medical implants, and relates to a foldable integrated artificial lens with a brown iris diaphragm. The foldable integrated artificial lens comprises the iris diaphragm, a central transparent optical area and/or haptics and is characterized in that the optical part of the artificial lens is integrated and formed by one whole material, and the material is a foldable hydrophobic acrylate material. The artificial lens has the advantages that the artificial lens is soft and can be folded and implanted into an eye through a small cut, surgical operation is simple, little postoperative astigmatism is caused, fast healing and fast visual function recovery are achieved, and little postoperative treatment is needed; and the brown iris diaphragm (which is the natural-color iris of Chinese) is used, the eye implanted with the artificial lens looks natural, and the width of the iris diaphragm can be appropriately selected according to the measuring result of the white to white distance of the eyeball.

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.

An ocular implant for treating glaucoma includes a tube (32) and a flanged disc (34) connected to the outlet end of the tube (32). The tube channel (38) is sized small enough to inhibit the outflow of aqueous humor from the tube channel (38) when the IOP is below a threshold. An inlet end of the tube has a beveled surface (40) and one or more peripheral holes (42). One or more outwardly extending retention protrusions are provided for anchoring the implant in the eyeball. The flanged disc has an outer rim and one or more inner posts. The implant is implanted by a handle and a rod-mounted instrument (60), the rod-mounted instrument (60) has a tip for insertion into the tube channel of the implant, and a retaining structure for securing implant.
