International Classification:

G06G 7/60

US Classification:

703 11

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.

International Classification:

A61F 2/16

US Classification:

623 643

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.

International Classification:

A61F 2/16

US Classification:

623 643

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.

Anew Optics, Inc. - Bristol TN

International Classification:

A61F 2/16

US Classification:

623 643

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.

International Classification:

A61F 2/16

US Classification:

623 623

Abstract:

An intraocular lens optic (e.g. FIG. ) having a maximum thickness of 500 microns () and a diameter of 6 millimeters, with concentric rings on the anterior surface of the lens. The lens, coupled with suitable haptic designs, is to be implanted within the lens capsule () of the eye after surgical removal of the natural crystalline lens. The anterior surface of the lens () has concentric rings () with steps of approximately 10 microns () that can be concave, convex or piano, with the edge of the step parallel in each case to the light rays traversing the lens at that point. The posterior surface of the lens () is aspherical and smooth. The concentric rings focus 95% or better of light at a specific target point on the retina, thus making a monofocal lens, with focal flexibility provided through haptic design providing movement of the lens forward in the posterior chamber in response to contraction and expansion of the ciliary body and concomitant repositioning of the zonules. The inventive lens is a unitarily formed, seamless body comprised preferably of hydrophilic acrylates or acrylates and silicone blends. Other possible materials include hydrophobic acrylates, polymethylmethacrylate (such as for example PMMA) or acrylic blends. The inventive lens, being less than 500 microns thick, provides greater transfer of light through the lens, thus more closely replicating the function of a natural, emmotropic lens, while the thinness, making the lens lightweight, allows the ciliary body to move the lens with less effort, thus facilitating comfort in the presbyopic eye.

International Classification:

US Classification:

623 649

Abstract:

The inventive is directed to 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. 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. At the connection point of the ribbon portion to the solid end plate of the haptic, the haptic may be notched to facilitate compressing the lens into its injector for insertion into the eye through an incision in the cornea. Once compressed and passed through the cornea, the implanted lens will be secured by the haptics in the lens capsule once all possible natural lens material and epithelial cells have been removed.
