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.

A cannula for use in cataract surgery during the phases of hydrodissection and hydrodelamination/hydrodelineation/hydrodemarcation is described. The cannula has a hub for mating with a syringe and a needle originating from the distal end of the hub. The needle comprises a first section, second section, and truncated surface. The first section originates from the distal end of the hub and extends forward in a plane delineating the central longitudinal axis of the cannula. The second section originates from the distal end of the first section and is flattened and curved away from the central longitudinal axis of the hub. The truncated surface of the needle forms a rounded tip with beveled surfaces. The intersection of the bevel and sides of the cannula are sharpened to provide a cutting edge.

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.

The invention relates to a novel apparatus for the treatment of ocular disease, particularly glaucoma. The apparatus consists of a locating device to locate Schlemm's Canal within the anterior portion of the eye and a surgical tool to access the canal for treatment. The apparatus allows for guided, minimally invasive surgical access to Schlemm's Canal to enable surgical procedures to be performed on the canal and trabecular meshwork to reduce intraocular pressure. The apparatus may also deliver devices or substances to Schlemm's Canal in the treatment of glaucoma.

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.

An accommodating intraocular lens implant for implantation in a human eye, including an optic adapted for coaxial alignment with a vision axis of the human eye, and at least one haptic. The haptic includes an anchor portion for receipt in one of a periphery of a capsular bag of the human eye, a cilairy sulcus of the human eye, and an angle of the anterior chamber of the human eye, and a sinuous portion extending radially from the optic and including a proximal end connected to the optic, a distal end spaced from the optic and connected to the anchor portion, and at least four curves successively connected between the proximal end and the distal end. The sinuous portion is adapted to flex upon ciliary muscle action to move the optic along the vision axis and allow the intraocular lens implant to automatically accommodate.
