An apparatus includes an intraocular pseudophakic contact lens configured to be implanted in an eye and mounted on or attached to an artificial intraocular lens in the eye. The intraocular pseudophakic contact lens includes (i) an optical lens and (ii) haptics extending radially from the optical lens and configured to be inserted under an anterior leaflet of a capsular wall in the eye. Posterior surfaces of the haptics include ridges configured to capture at least one edge of the artificial intraocular lens. The haptics are flexible such that outer portions of the haptics are configured to drive the ridges into the at least one edge of the artificial intraocular lens based on surface pressure from the anterior leaflet against the outer portions of the haptics.

An intraocular lens for implantation in a capsular bag of an eye comprising a membrane, an internal cavity, and a gas. The membrane may include an anterior face and a posterior face. The anterior and posterior faces may be joined together at a periphery of the membrane. The membrane may include at least one optical element associated therewith. The internal cavity may be defined within the membrane. The gas may be positioned within the internal cavity. The gas may be operable to separate the anterior and posterior faces of the membrane. The intraocular lens may be neutrally buoyant within the capsular bag.

A tunable prism for vision correction of a patient and other applications is disclosed herein. The tunable prism includes a first transparent plate; a second transparent plate; and a transparent balloon, a transparent ball, a transparent gel, or a transparent bag filled with a transparent gel disposed between the first and second transparent plates. A tilt of at least one of the first and second transparent plates is configured to be modified so as to adjust a prism diopter of the tunable prism.

A lens for use in an intraocular lens system for treating age-related macular degeneration (AMD), the lens including an anterior surface, a posterior surface, and a plurality of haptics configured to align the anterior light-converging intraocular lens with an optical axis of the eye. The plurality of haptics may have a symmetrical design and comprising ciliary-sulcus-engaging surfaces configure to position the lens within in a ciliary sulcus of an eye. At least one of the anterior surface and the posterior surface may be rendered as aspherical surfaces selected to induce spherical aberration while minimizing optical aberration and thereby provide for a continuum of retinal images to be focused at an area macula of a retina of the eye between two retinal eccentricities.

Accommodating intraocular lenses with a combination of variable power lenses including, firstly, a variable lens with cubic surfaces fitted onto two optical elements to vary focal power by lateral shift of the elements and, secondly, a variable lens with spherical lenses fitted onto the same elements to vary focal power by axial shift of the elements. A mechanical construction with hinges provides both the shifts of the elements.

An eye lens having a front lens element and a rear lens element, which each have a positive optical power and an optical region, and an intermediate element, which is connected to the lens elements outside the optical regions so that the lens elements and the intermediate element form a cavity. The eye lens allows the width of an access incision necessary for implantation to be reduced. The eye lens includes the lens elements and the intermediate element that are shaped such that, in the implanted state, a distance between the front lens element and the rear lens element is fixed and the cavity has an opening which allows liquid to flow into the cavity. Embodiments of the invention include a method for producing such an eye lens and a method for implantation.
