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.

Abstract: An accommodating intraocular implant apparatus is disclosed for implantation in the human eye. The apparatus includes an optic portion having a periphery and an optic axis, said optic portion lying substantially within an optic plane transverse to said optic axis; at least one flexible haptic extending from a point on or near the periphery of the optic portion; at least one flexible haptic having a fixation anchor portion distal to the periphery of the optic portion; and at least one flexible haptic having a centering anchor portion. The fixation anchor portion and the centering anchor portion are adapted to couple to a portion of the eye.

Abstract: An intraocular lens (IOL) assembly for correcting myopia, hyperopia and astigmatism is provided. The intraocular lens assembly comprises a lens extending along an optical axis between an anterior optical surface and a posterior optical surface. The IOL has a circumferential edge disposed about the optical axis at a junction of anterior and posterior optical surfaces with N haptics, where N is an integer greater than 1. Each haptic extends from an associated portion of the circumferential edge and along an associated haptic axis and extends between end portions joined to the lens at the circumferential edge. Each of the haptics includes M footplates extending symmetrically about its associated haptic axis, where M may be an integer greater than 0. The resultant vaulted structure provides an intraocular lens assembly that, when implanted in the eye, allows accommodation.

Abstract: A haptic for fixation to, and manufacture in conjunction with, an intraocular lens to be implanted in the natural lens capsule of the human eye is disclosed. The haptic secures the lens in an appropriate position within the natural capsule so as to provide optimal visual acuity through the aphakic lens. The haptic ends are designed to position the lens neutrally, anteriorly or posteriorly within the lens envelope. The haptic has a of an anterior retention ring and a posterior retention ring.

Abstract: The invention is directed to a lens that comprises an optic and 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 positioned against the posterior capsule as close as possible to the nodal zone of the eye.

Abstract: The invention is directed to an assembly comprising a haptic for fixation to, and manufacture in conjunction with, an intraocular lens to be implanted in the natural lens capsule of an eye. The haptic of the invention comprises a continuous ribbon forming an essentially oblong shape having anterior and posterior portions relative to the elliptical center of the haptic, wherein the ribbon loop includes two or more essentially congruent ribbon arches in each portion, and each ribbon arch has a natural index of curvature with an inner and outer edges. designed to expand the eye capsule and put tension on the zonules of the eye. The ribbon affixes to the lens on each side of the optic edge at a point or a series of points that provides suitable centration and stability of the optic, and to suspend the optic in the open capsular space.

Abstract: The invention is directed to a model comprising a diagrammatical and geometric simplification of the components of the natural eye whose functionality is fundamental to the successful performance of a pseudo-aphakic accommodative lens. This model allows for a functional correlation of each component of the ophthalmic device with the patient needs. The eye model was developed to show the movement of the eye from the distance vision to the near vision positions through multiple phases of accommodative motion. The inventive model was developed using a mathematical series of formulas to calculate each of the components of focal accommodation in a human eye, quantify these, and construct the pictorial ramifications of such calculations. The inventive model presents an analysis of accommodative dynamics in the human eye with the natural lens in place. The inventive model also demonstrates the accommodative dynamics with a proprietary IOL in place of the natural lens and situated within the lens capsule.
