Abstract: A multi-focus intraocular prosthesis is provided that makes use of fluid substitution to change the power of the prosthesis. Also provided are methods of making and using the same.

Abstract: A prosthesis is provided, which includes anterior and posterior lenses spaced from one another and aligned along an optical axis, and an optic body supporting the lenses in spaced relation to one another to establish a chamber between the lenses. Optically transmissive primary and secondary fluids are contained in the chamber. Orienting the optical axis in a horizontal orientation for far vision positions the optical axis through the primary fluid. Orienting the optical axis for near vision at a range of effective downward angles relative to the horizontal orientation positions the optical axis to extend through the primary fluid and the secondary fluid. The prosthesis may further include an internal plate between the lenses, which may be offset at an oblique angle relative to perpendicular to the optical axis. Related methods are also provided.

Abstract: An intraocular device including a prism and shift amplifier is provided. Also provided is a system containing the intraocular device, and a method for improving vision of a person with central vision loss. The method involves implanting the intraocular device in the person so that the prism and shift amplifier cumulatively shift a retinal image away from the fovea of an eye to a functional retinal portion of the eye. Also provided is a method for correcting a binocular misalignment of a person using the intraocular device.

Abstract: This intraocular lens includes an optic body having anterior and posterior walls, a chamber, and optically transmissive primary and secondary fluids, and method for making and using the same. The secondary fluid is substantially immiscible with the primary fluid and has a different density and a different refractive index than the primary fluid. The primary fluid is present in a sufficient amount that orienting optical body optical axis horizontally for far vision positions the optical axis through the primary fluid, thereby immersing the anterior and posterior optical centers in the primary fluid. The secondary fluid is contained in the optic body in a sufficient amount that orienting the optical axis at a range of effective downward angles relative to the horizontal for near vision positions the optical axis to extend through the primary fluid and the secondary fluid, thus changing the focus of the intraocular lens.

Abstract: A magnifying contact lens storage unit that comprises a body having at least one cavity with a top opening, at least one magnifying lens, and a fluid-tight closure lid fixedly attached to the top opening. The body may further have a planar flange, and the magnifying lens may be within the flange, the cavity, the closure lid, or within any combination of those structures. The magnifying lens has a predetermined magnification power for permitting viewing and inspection of the contact lens after removal of the contact lens from the storage unit. The body, flange, and/or closure lid may be optically transparent, and may fit exteriorly within an orbital aperture of a contact lens wearer's face.

Abstract: A soft or rigid gas permeable silicon elastomer contact lens bonded with either titanium, titanium monoxide, titanium dioxide, dititanium trioxide, trititanium pentoxide, and mixtures thereof to form contact lens having high oxygen permeability, improved wetting ability, decreased fogging ability, an enhanced self-cleaning characteristic, and decreased transmissibility to ultraviolet radiation. Preferred methods of incorporating the additives is by cationic polymerization of either a coating of or in situ bonding to a silicon polymer resulting in the expression of the additive toward the exterior surface of the chemical matrix of the contact lens. Other bonding methods are electron beam evaporation., sputtering and ion implantation of the titanium additive.
