The haptic and optic may be refractive index-matched. The cap may be made of the haptic material, which is stiffer than the optic material, and can influence the deformation of the lens during accommodation. A cap on the anterior surface may produce an axial movement of the lens in an anterior direction during accommodation. The cap may also protect the surfaces of the optic during handling and installation.

    Abstract: An intraocular lens (IOL) has been provided with an accommodation assembly that effects axial movement of the IOL optic through both the radial action of ciliary muscles and the axial forces resulting from vitreous pressure on the posterior wall of the capsular bag. In a preferred embodiment, the assembly comprises an IOL having substantially rigid, posteriorly extending fixation members which extend through slots in an accommodation ring encircling the optic. Axial forces exerted by vitreous fluids on the posterior wall of the capsular bag are transmitted from the posterior wall to the ring to the fixation members at the slot areas, causing axial movement of the IOL. At the same time, the angulation of the haptics converts radial forces due to contraction or expansion of the capsular bag into axial forces, causing still more axial movement of the IOL.

  • Publication number: 20040260395
    Abstract: The invention comprises a device for treating presbyopia. A stretch segment is provided for implantation into the region extending between the outer circumference of the lens and extending to the sulcus region at the intersection of the iris and ciliary body. The stretch segment engages the equatorial zonules spanning between the lens and ciliary body. The segment is designed to take up slack in the equatorial zonules in the presbyopic eye, such that their effective working distance is enhanced. This aids in the accommodation process which affects the curvature of the lens for near viewing. The segment may a closed ring, or may be open ended.

  • Patent number: 6749634
    Abstract: An accommodating intraocular implant for locating in the capsular bag, the implant comprising a single piece of elastically deformable material constituting a central lens (1) and at least two haptic portions (2, 4) in the form of radial arms for bearing via their free ends against the equatorial zone of the capsular bag, the free end of each radial arm (2, 4) being fitted with a shoe (6, 7) of substantially toroidal outside surface enabling the implant to bear against the equatorial zone of the bag, the connection between each shoe (6, 7) and the corresponding arm (2, 4) being of the hinge type situated in the vicinity of the posterior edge of the shoe (6, 7) and being formed by a first thin portion (2d, 4d) of the arm, while the connection between each arm and the lens is of the hinge type implemented at the anterior surface of the lens by a second likewise thin portion (2c, 4c) of the arm, the plane (P1) containing the first thin portions being situated behind the plane (P2) containing the second thin port

  • Publication number: 20040082995
    Abstract: An intraocular lens having an anterior lens member (48) presenting an anterior light-converging optic (58) and a posterior lens member (50) presenting a posterior light-diverging optic (50) for magnifying an observed image onto large regions of the retina (32) to permit central focus in patients suffering from AMD and a method of implanting said lens into the human eye (10). The anterior light-converging optic (58) is operably coupled with a flexible body (58) which extends radially therefrom and presents opposing bights (62) presenting termini (66) when the lens is viewed in cross-section. The posterior light-diverging optic (68) is operably coupled with an annular flange (76) which is arcuate in cross-section and mates with termini. Both the anterior and the posterior lens members (48, 50) have positioning holes (70, 80) formed therein permitting surgical implantation thereof.

  • Publication number: 20040039446
    Abstract: An intraocular lens (IOL) has been provided with an accommodation assembly that effects axial movement of the IOL optic through both the radial action of ciliary muscles and the axial forces resulting from vitreous pressure on the posterior wall of the capsular bag. In a preferred embodiment, the assembly comprises an IOL having substantially rigid, posteriorly extending fixation members which extend through slots in an accommodation ring encircling the optic. Axial forces exerted by vitreous fluids on the posterior wall of the capsular bag are transmitted from the posterior wall to the ring to the fixation members at the slot areas, causing axial movement of the IOL. At the same time, the angulation of the haptics converts radial forces due to contraction or expansion of the capsular bag into axial forces, causing still more axial movement of the IOL.

  • Publication number: 20040034416
    Abstract: A capsule clamping ring for implantation in the emptied capsule of the human crystalline lens which can permanently counteract a shrinkage of the capsule thanks to the fact that it can be stiffened after implantation. The open ring—as required for implantation—is designed in such a manner that it can be welded inside the eye. For this purpose, the open ends must touch, the area of contact must be visible through the pupillary opening and thus accessible for the laser, and the colour of the material and the surface geometry must be designed in such a manner that, when irradiated with a laser, locally circumscribed, merging melting zones can form.

  • Publication number: 20030204256
    Abstract: A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly against the posterior capsule. The periphery of the first optic contains a pair of clasps. The second optic is located anteriorly to the first optic and is of a positive power. The peripheral edge of the second optic contains a pair of locking arms that fit into the clasps contained on the periphery of the first optic to lock the second optic onto the first optic, but allow for rotation of the arms within the clasps. Hinge structures on the locking arms allow the second optic to move relative to the first optic along the optical axis of the lens system in reaction to movement of the ciliary muscle.
