Abstract: An intra-ocular artificial lens with variable optical strength, having at least two optical elements, at least two of which are movable relative to each other in a direction extending transversely of the optical axis, wherein the optical elements have a form such that in different positions of the movable optical elements the artificial lens has a different optical strength, wherein the artificial lens has a fixed, positive optical basic strength wherein the variable optical strength caused by the relative movement of the movable elements is added to obtain the total optical strength of the artificial lens. Providing a different form results in the possibility of incorporating the greatest optical power in one of the optical elements. This optical element can then be optimized for the desired optical properties. The remaining optical element or the remaining optical elements can then be dimensioned for variation of the optical strength.

Abstract: The embodiments herein provide a pupil centered and fovea focused optics assembly comprising a ring platform provided inside a capsular bag of a mammalian eye to support an intraocular lens. The optical center of the intraocular lens is decentered with respect to the geometric center of the intraocular lens to align the optical centre of the lens with a visual axis of a pupil of the mammalian eye to improve the visual quality and to prevent an aberration. A plane of the intraocular lens is turned and tilted through a preset angle to point an optic axis of the intraocular lens to the Fovea.

Abstract: An accommodating intraocular lens implantable in an eye. The lens comprises an anterior portion having an anterior biasing element and an anterior optic having refractive power. The lens further comprises a posterior portion having a posterior biasing element and a posterior optic having refractive power. The anterior optic and the posterior optic are relatively moveable in response to action of the ciliary muscle to change the separation between the optics and the refractive power of the lens. The lens has an aberration-inducing force characteristic of about 70 mg to about 115 mg to allow aberration-inducing relative movement of the optics when the lens is in the eye, thereby adding optical aberration to the lens which increases depth of focus of the lens. In one variation, the lens has an aberration-inducing force characteristic of 70 mg to 115 mg. Related methods are also disclosed.

Abstract: An intraocular lens for implantation within an eye after cataract surgery. The intraocular lens has a haptic having an elongated gently curving seating portion having a free end and a weakened portion about which such seating portion pivots. The weakened portion is spaced from the fulcrum formed at the location at which the haptic is anchored to the lens body such that the free end of the seating portion moves toward the lens body in response to compression of the seating portion toward the lens body for facilitating seating thereof, while minimizing the risk of injury to the delicate membranes in the eye by outwardly extending distal portions of the haptics. The construction of the lens being such that except for the weakened portion of the haptic, the entire haptic, including the seating portion, would pivot about the point of connection of the haptic to the lens body with the result that the free end portion would move away from, or at least not toward, the lens body, in response to such compression of the seating portion.

Abstract: The present disclosure provides an ophthalmic lens (such as an IOL) that is designed to enhance depth of focus for intermediate vision performance, while maintaining distance vision. The lens may include an optic having an anterior surface and a posterior surface disposed about an optical axis. One of the surfaces (e.g., the anterior surface) may have a surface profile involving a superposition of at least three structures or profiles, including a base structure, a phase shift structure having an inner region, an outer region and a transition region, and a zonal structure having an inner power zone and an outer transition zone.

Abstract: A multi-piece IOL assembly is provided that includes a platform and an optic. The platform has an inner periphery surrounding an inner zone of the platform. The optic has an optical zone, an outer periphery and a retention mechanism disposed on the outer periphery. The optic is configured to be disposed in the inner zone of the platform and to extend to a location between the inner periphery and the outer periphery of the platform to be secured to the platform at the location. The platform can be secured to an inner periphery of the eye or can be formed into a natural lens by cutting the lens using a laser or other energy source.
