Provided is an artificial retina system for improving contrast sensitivity. The artificial retina system includes an artificial retina which is installed under the retina and includes a plurality of photodiode cells and a microcomputer. The microcomputer compares, with at least one reference value, the magnitude of an electric signal outputted from a photodiode in each of the photodiode cells. The microcomputer controls to amplify or reduce the electric signal outputted by each of the photodiode cells according to the result of comparison. Visual cells corresponding to each of the photodiode cells can be stimulated with an electric signal controlled by the microcomputer.

A method for performing a corneal transplantation comprising the steps of: inserting at least part of a corneal implant into the anterior chamber of the eye, the corneal implant comprising an implant portion and a manipulating portion, the manipulating portion comprising non-endothelial tissue; positioning the implant portion of the implant to adhere to the posterior surface of the cornea using the manipulating portion.

A capsular tension ring inserter (10) and method includes a cannula (54) adapted to house a capsular tension ring (CTR) (26) having a leading eyelet (32), a hook element (56) disposed within the cannula (54) that engages and moves the CTR (26) during deployment, and a suture (28) placed on the leading eyelet (32) and fed back through the cannula (54) to allow a user to control insertion of tile CTR (26) into a capsular bag (42) of an eye (40) by pulling on the suture (28) during insertion of the CTR (26).

Corneal implant (1) designed for correcting irregularities of the corneal curvature of a subject, the implant (1) having a generally dome-shaped structural body (2) configured to impose a regular curvature to the corneal portions designed to be in contact with the implant, wherein the structural body comprises an outer peripheral ring (10) and an inner reticular structure (20), wherein the inner reticular structure (20) comprises at least one first and one second series of beams (21, 22) intersecting each other, the beams (21) of the first series having a respective first end (31) connected to the outer peripheral ring (10), wherein the total area of void portions (24) within the meshes of the reticular structure (20) is between 50 and 99.9% of the surface area of the reticular structure (20).

A structured artificial construct that allows corneal endothelium to be regenerated from isolated cells outside the human or animal body is provided. The structured artificial construct is formed from a dome-shaped base body with a honeycomb structure formed in a concave side of the base body. Methods for generating the structured artificial construct are also provided.

Contact lens that, during use, creates a hollow space between its concave internal surface and the convex external surface of the eye and contacts the corneal epithelium only for a fraction of its internal surface facing toward the eye thanks to the presence of a plurality of micro-protuberances which allow to raise the contact lens by a few micrometers with respect to the corneal surface.

An ophthalmic pinhole prosthetic and a method of fabricating the same. The ophthalmic pinhole prosthetic comprises an annular portion, an inner perimeter, and an interior light transmitting portion. The annular portion may be optically opaque or at least partially optically opaque. The inner perimeter may include surface modifications configured to reduce or substantially eliminate diffraction of light compared to an ophthalmic pinhole prosthetic without the surface modifications. The interior light transmitting portion may be located within the annular portion and function to allow passage of light to interact with a retina.

An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.
