    Abstract: Disclosed is an intraocular lens assembly provided inside a capsular sac. The intraocular lens assembly according to one embodiment of the present invention includes an intraocular lens and an intraocular lens supporter, and therefore the intraocular lens assembly may be useful to transfer a force to the intraocular lens, inserted inwardly into the capsular sac, to allow the intraocular lens to move like a natural eye lens, the force being generated from the ciliaris muscle and transferred through the zonule of Zinn and the capsular sac.

  • Publication number: 20130317606
    Abstract: A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

  • Publication number: 20130304206
    Abstract: Provided herein are a devices, ophthalmic lens systems and methods for restoring natural tension and anatomy of a lens capsule post-surgically in an eye of a subject. The device generally comprises an inward tensioning ring-like structure having a shape configured to circumferentially fit within and be anchored to a post-surgical lens capsule of the eye. The device may have one or both of external and internal grooves formed to receive the lens capsule and one or both of an intraoptical lens or a tensioning element. The ophthalmic lens system generally comprises the device and an intraocular lens inserted therein. The anchored device provides tension to an equatorial area of the capsule resulting in a decrease in equatorial diameter.

  • Publication number: 20130231742
    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.

  • Patent number: 8496701
    Abstract: An intraocular lens for providing accommodative vision to a subject includes a frame disposed about an optical axis, a first optical element, a second optical element, and a connecting element operably coupling the frame to the optical elements. The frame comprises an anterior frame element and a posterior frame element. The connecting element is configured to convert a first displacement between the frame elements in a direction that is substantially parallel to the optical axis into a second displacement between the optical elements that is substantially perpendicular to the optical axis. The second displacement may be translational and/or rotation. In some embodiments, the optical elements are two varifocal lenses.

  • Publication number: 20130184816
    Abstract: The invention is directed to a lens that comprises an optic and at least two haptic rings, one positioned to rest against the posterior capsule distally outward from the optic zone, the other to rest on the anterior capsule some distance from the equator. The haptic rings of the lens are connected by segments of haptic material that may be arched or straight, and sections of open space to provide for ample circulation of the aqueous humor. The optic is suspended between the two haptic rings such that the distance between the optic and the anterior ring is constant while the distance between the optic and the posterior ring may vary according to the overall capsular dimensions of the eye of the patient.

  • Patent number: 8475529
    Abstract: An accommodating intraocular lens, for use in an eye, is made from flexible, optionally elastic, bio-compatible lens body material surrounding a closed and sealed lens cavity. One or more compressible struts is in the cavity. The cavity is filled with bio-compatible optical liquid. The optical liquid has a refractive index sufficiently high to, in cooperation with the ciliary muscle and the compressible strut, focus light, incident on the eye, on the retina, thus to provide accommodation. The curvature of the surface of the lens is deformable, by the forces expressed by the ciliary body and the strut, thus to change the radius of curvature of the anterior body member and/or the posterior body member, thus providing focusing, including from relatively farther distance in the relaxed state to relatively nearer distance in the accommodative state.

  • Publication number: 20130166026
    Abstract: An accommodating intraocular lens for providing a range of accommodative vision contains an optic and a haptic. The optic is disposed about an optical axis and includes an anterior surface and a posterior surface defining a clear aperture of the optic. The haptic is at least partially disposed inside the optic and includes an inner structure, an outer structure, and a plurality of arms disposed between and connecting the inner structure and the outer structure. The inner structure is circumferentially disposed about the optical axis, while the outer structure is circumferentially disposed about the inner structure and has an outer face. Each arm has proximal portion adjacent the inner structure and a distal portion adjacent the outer structure that is bifurcated in a radial direction from the proximal portion. The intraocular lens also has an outer surface defined by outer surfaces of the plurality of arms and an outer surface of the outer structure.

  • Patent number: 8449611
    Abstract: An intraocular lens comprises an optic portion having a peripheral edge and at least two haptics. Each haptic is integrated with the peripheral edge of the optic portion by a corresponding haptic integration region. Also, each haptic comprises a distal segment region and a deformation segment region. The distal segment region has an outer distal length bounded by a proximate endpoint and a distal endpoint on an outer surface of the haptic, and is scribed by a distal segment angle ? of 20° to 30°. The distal segment angle has a segment origin that lies within a radial segment bound by a radial distance 1.5 mm to 1.9 mm from an optic center and a segment angle ? of from 30° to 45° from a vertical axis. The vertical axis extends through the distal endpoint of at least one haptic and the optic center.
