Reversibly deformable corneal implants for replacing excised corneal tissue, the implants including an optical portion and an anchoring portion having different mechanical properties from each other.

Reversibly deformable corneal implants for replacing excised corneal tissue, the implants including an optical portion and an anchoring portion having different mechanical properties from each other.

An intraocular lens includes a substantially circular lens element formed of a transparent material and one or more haptics extending outwardly from an outer edge of the lens element. The one or more haptics are formed of a polymer foam material having a negative Poisson's ratio (NPR) and are configured to couple the intraocular lens to an eye of a patient. The lens includes an inner region having a first index of refraction and an outer region disposed circumferentially surrounding the inner region, the outer region having a second index of refraction different from the first index of refraction.

An embodiment in accordance with the present invention provides an apparatus and method for inserting a lens into pocket in the cornea. The apparatus includes a handle, a plunger extending movably through the lumen of the handle, and a first and a second actuators. In particular the plunger includes a distal segment which extends beyond the distal end of the handle and the first and second actuators are coupled to the plunger configured in such a way to provide different ranges of motion and synchronized movement of a bottom, middle, and top tines of the plunger for improved and safer lens insertion into the corneal pocket.

A method of inserting and securing a corneal implant in engaging and fluid-flow limiting relation to the posterior cornea, such as to treat edema. The method includes securing a corneal implant in fluid flow limiting relation to the posterior cornea through an incision in the eye and securing it in place by a variety of steps such as corneal insertion or laser bonding, and preferably by inserting a removable corneal implant including a central region and a plurality of retention member(s) disposed on the periphery thereof into the eye so as to releaseably and removably engage a portion of the eye and thereby retain the corneal implant in abutting and engaging relation with the posterior cornea. The retention members of the corneal implant may also comprise haptic leg(s) extending from the central region.

A device (1) for eye surgery includes a metallic ring (2) for suturing to the sclera of a patient's eye. A locking element (3) can be coupled to the metallic ring (2). The locking element (3) includes a lens (31) and a coupling ring (32) fixed to the lens (31) along the entire circumference of the inner edge of the lens (31). The coupling ring (32) is configured for coupling to the metallic ring (2).

The invention provides keratoprosthesis devices and kits and surgical methods of their use.

Disclosed herein is a prosthesis that may be used to replace standard prosthetic material used in osteo-odonto-keratoprosthesis (OOKP) surgery. The disclosed prosthesis is not prepared from tissue removed from a patient's tooth and jaw bone, but rather is a synthetic prosthesis. The synthetic prosthesis typically includes a solid part for supporting an optical cylinder and a porous part that facilitates bio-integration of the implanted prosthesis into the patient's eye.

A tear shaping structure or structures that shape a tear film of an eye thereby enabling a desired refractive effect. The tear shaping structure includes a supporting structure supporting a plurality of capillary action members, the capillary action members being spaced apart and arranged in such a way as to create a desired refractive lens effect by shaping the tear film of an eye.

A corneal implant (10) includes a central portion (12) and a peripheral skirt (14) extending outwards from the central portion (12), and at least a portion of the peripheral skirt (14) includes a mesh (16).
