An artificial iris having a pouch includes a top iris, a bottom iris, and more than two fixing rings. The center of the top iris is formed with an inner hole. The outer edges of the top iris and the bottom iris are fixed together to form the pouch. Atop junction of the top iris and the bottom iris is formed with an opening for implanting an intraocular lens. The more than two fixing rings are fixedly mounted on a back surface of the bottom iris. A suture passes through the fixing rings of the artificial iris and is fixed to the scleral wall.

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.

A refractive intraocular lens (104) and method of locating the lens within the eye and attaching the lens to the iris. The refractive intraocular lens (104) may be attached via a staple (230), a fastener (312), anchor (412) or by the tip of the haptic (118). The intraocular lens (104) works in combination with the human crystalline lens to treat conditions selected from the group consisting of myopia, hyperopia and astigmatism.

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 releasably 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 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.

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.
