An ophthalmic prosthetic and method for correcting negative and positive dysphotopsia. The ophthalmic prosthetic comprises a peripheral light blocking implant member adapted to locate in a gap between an iris and an intraocular implant lens. The gap is between the anterior surface of the lens and the posterior portion of the iris. An opacity of the peripheral light blocking implant member is selectively positioned to block passage of light.

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.

The invention relates to an implant for implanting in and/or an eye using fixing means enabling improved fixing, in particular with respect to the natural variability of the anatomical conditions of the eye. According to the invention, the fixing means comprise at least one support element which can be mounted on a tissue structure in the direction traverse to the optical axis of the eye.

Intraocular lenses and related assemblies and intraocular attachment methods are disclosed herein. In one embodiment, an intraocular lens assembly comprises a helical-shaped coil fastener to affix an intraocular lens to an iris to correct for astigmatism, presbyopia, and/or myopia or hyperopia. The helical-shaped coil fastener comprises a head and a helical wire extending from a bottom surface of the head and comprising a pointed tip opposite the head. The helical-shaped coil fastener is configured to be affixed to the iris by rotatable penetration of the iris, and thus can be removed from the iris by reverse rotation of the helical-shaped coil fastener. The helical-shaped coil fastener has a low volume, large surface area, low cross-sectional area of penetration, and an oblique angle of penetration. Thus, the helical-shaped coil fastener is easy to apply, easy to remove, minimizes tissue damage, maximizes stability, and minimizes penetration force.

Systems and methods can advantageously leverage the pupillary accommodation reflex to provide improved quality of vision throughout the range of focus distances. As such, some embodiments include an accommodating pupillary lens (APL) that sits at least partially within the pupil and/or is partially or fully attached, adhered, or otherwise held in place with respect to the iris, and/or is anchored in the sulcus and/or elsewhere in the eye. The optical power of the lens can be configured to change with changes in pupil diameter.

An intraocular lens 1 includes a lens 2 and a haptic 3 connected to the lens 2. The lens 2 is disposed behind an iris 7 in an eye of a patient. The haptic 3 has a main body 3a and first and second projections 3d and 3e. The main body 3a extends from the lens 2 outward in a radial direction about a visual axis C of the patient. The first and second projections 3d and 3e are located so as to project from the main body 3a toward spaces between a plurality of ciliary zonules 10 connecting a crystalline lens 11 and a ciliary body 8 in the eye. Accordingly, an intraocular lens and a haptic for an intraocular lens that are able to inhibit the position of a lens from being displaced are provided.

A hook portion 4 is provided which is formed so as to extend from base portions 21a of the ciliary processes 21 along the outer surfaces of the ciliary processes 21 via anterior end portions 21b of the ciliary processes 21 to base portions 21c at the opposite side. A leg portion 3 extending from the hook portion 4 toward the visual axis C is connected to the hook portion 4, and a lens 2 to be mounted in the eye of the patient is supported by the leg portion 3. The lens 2 is held in the eye of the patient in a state where the hook portion 4 is hooked or fitted to the ciliary processes 21.

A method of positioning an accommodating intraocular lens assembly in an eye can include implanting an accommodating intraocular lens assembly having a positive power lens in the eye. The accommodating intraocular lens assembly can also include a plurality of stanchions extending between base ends and distal ends. The base ends can be disposed in spaced relation to one another about a first arcuate periphery positioned in a ciliary sulcus of the eye. The distal ends can be disposed about a second arcuate periphery extending in a second plane positioned forward and outside of a capsular bag of the eye. The positive-power lens can be connected with the plurality of distal ends whereby a center of the positive power lens is moved along the central optic axis in response to contraction of the first arcuate periphery by contraction of the ciliary sulcus.
