Abstract: A foldable intraocular lens for providing vision contains an optic body that includes an optical zone and a peripheral zone entirely surrounding the optical zone. The optic body has an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis. The anterior face comprises a central face, a peripheral face, and a recessed annular face therebetween that is disposed posterior to the peripheral face. The intraocular lens further comprises at least one haptic that is integrally formed with the peripheral zone. The haptic comprises a distal posterior face, a proximal posterior face, and a step edge disposed at a boundary therebetween. The haptic further comprises a side edge disposed between the optic edge and the step edge. The proximal posterior face and the posterior face of the optic body form a continuous surface. An edge corner is formed by the intersection of the continuous surface with the optic edge, the side edge, and the step edge.

Abstract: An ophthalmic lens for providing enhanced vision includes a finished optic comprising a base optic and a membrane. The base optic has an anterior surface and an opposing posterior surface, at least one of the surfaces having a first value of a surface quality parameter. The base optic also includes a membrane including an inner surface and an outer surface, the inner surface covering one or more of the surfaces of the base optic. The outer surface has a second value of the surface quality parameter, wherein the second value is greater than the first value.

Abstract: This apparatus treats the lens capsule so as to increase accommodation of the eye. The treatment of the lens capsule may comprise treating a portion of the lens capsule so as to stiffen the treated portion and improve accommodation of the eye. The intermediate portion of the lens capsule may be located between an optically used central portion of the lens capsule and a peripheral portion of the lens capsule connected to zonules of the eye. The stiffened intermediate portion of the lens capsule can improve coupling of the peripheral portion of the lens capsule to the central portion of the lens capsule, such that an amount of accommodation of the optically used central portion of the lens is increased. As the force of the lens capsule to a lens disposed within the lens capsule is increased, the lens may comprise the natural lens of the eye or an artificial lens such as an accommodative IOL.

Abstract: An accommodating IOL comprises an optic adapted to focus light toward a retina of an eye, and a movement assembly coupled to the eye to provide effective accommodating movement, preferably axial movement, of the optic. At least a portion of the movement assembly is made from a material that is less stiff and/or more resilient than the material used to make the optic. Optionally, an outer ring or support portion made at least partially from either a relatively stiff material such as the material used in the optic or a relatively resilient material such as the material used in the movement assembly is also provided.

Abstract: An intraocular lens for providing a range of accommodative vision, an extended depth of focus, or enhanced performance through the asymmetric transfer of ocular forces to the lens. The intraocular lens contains an optic and a haptic. The shape and/or material of the haptic results in the transmission of ocular forces to particular regions in the optic. Greater forces applied to particular regions result in deformation of that region and increased power.

Abstract: An intraocular lens implantable in an eye includes an optic for placement in the capsular bag of the eye and for directing light toward the retina of the eye. The optic has a central optical axis, an anterior face, an opposing posterior face and a peripheral edge between the faces. The peripheral edge has one or more curved or angled surfaces that reduce glare within the IOL. For instance, a rounded transition surface on the anterior side of the peripheral edge diffuses the intensity of reflected light, or a particular arrangement of straight edge surfaces refracts the light so as not to reflect, or does not reflect at all. The intersection of the peripheral edge and at least one of the anterior face and the posterior face, preferable both of such faces, forms a peripheral corner located at a discontinuity between the peripheral edge and the intersecting face or faces.

Abstract: A rear-loaded injector cartridge for an intraocular lens (IOL) having a proximal opening that provides a haptic slot. The haptic slot receives a leading haptic of an IOL loaded therein, and temporarily retains the leading haptic while the optic of the IOL is inserted into a holding area of the cartridge. As the optic passes by, the leading haptic folds over the top of the optic, on its anterior side. The length of the haptic retention slot is sufficient to maintain the leading haptic in its anteriorly folded position while the IOL remains in holding area, typically while the cartridge is mated with a handpiece of the injector. The cartridge also has a rear or proximal cut out which advantageously keys with a similarly-sized rail on the handpiece so that the cartridge cannot be inserted in the wrong way.

Abstract: An intraocular lens includes a deformable optic, a rigid optic, and a support structure. The deformable optic is disposed about an optical axis and comprises a solid material and a deformable surface. The rigid optic is disposed about the optical axis and comprises a solid material and a rigid surface. The support structure is operably coupled to at least one of the optics for pressing the deformable surface and the rigid surface together in response to or in the absences of an ocular force, whereby at least a portion of the deformable surface changes shape such that the optical power of the at least a portion of the deformable surface and/or the intraocular lens changes by at least 2 Diopter.

Abstract: A haptic is provided for use in an accommodating intraocular lens. The haptic has multiple filaments, each connected to the edge of the optic at one end. Each filament has a shape that conforms to an equatorial region of the capsular bag. The haptic couples the forces exerted by the capsular bag of the eye during accommodation radially to the edge of the optic, produce a diametric expansion or compression of the optic. This diametric motion distorts the optic, producing a change in any or all of the anterior radius, the posterior radius, and the thickness. These changes affect the power of the lens and/or location of the image. The haptic may optionally have a thin membrane joining the filaments at the optic end, and may optionally have a connecting ring that joins the filaments at the end opposite that of the optic.
