  • Patent number: 10376613
    Abstract: The present invention concerns a process for the production of implants with an ultrahydrophilic surface as well as the implants produced in that way and also processes for the production of loaded, so-called bioactive implant surfaces of metallic or ceramic materials, which are used for implants such as artificial bones, joints, dental implants or also very small implants, for example what are referred to as stents, as well as implants which are further produced in accordance with the processes and which as so-called “delivery devices” allow controlled liberation, for example by way of dissociation, of the bioactive molecules from the implant materials.

  • Patent number: 9717589
    Abstract: An accommodating intraocular artificial lens with variable optical power, comprising two optical elements which are adapted to mutually shift in a direction perpendicular to the optical axis wherein the optical elements have such a shape that the optical elements exhibit, in combination, different optical powers at different relative positions. Flanges are adapted to position the anterior section of the haptics in the sulcus of the eye or, alternatively, the ciliary body is enclosed by a combination of anterior and posterior flanges. Also disclosed are methods to provide for an accommodating intraocular lens which is adjustable post-implant to ensure emmetropia of the eye.

  • Patent number: 8728158
    Abstract: An exchangeable intraocular lens device having a flexible, high-memory expansile lens fixation platform adapted to receive the haptics of an intraocular lens, and their method of use, are provided. The device is specifically designed to expand completely into the equatorial fornix of the capsular bag and become permanently implanted therein. The design of the present invention addresses the desire of patients to exchange their existing intraocular lens to meet their changing visual needs or to take advantage of improved lens technology, without incurring the significant risks typically associated with exchange of current intraocular lens technology. The exchangeable intraocular lens device provides accurate centration, positioning, and stability of the intraocular lens in the capsular bag. The exchangeable intraocular lens device reduces lens epithelial cell migration and resultant posterior capsule opacification.

    Abstract: An intraocular implant for placement in the eye, e.g. as part of a cataract operation or crystalline lens extraction refractive operation, has at a peripheral portion of the implant a groove which engages with the lip of a single capsulotomy only formed in the lens capsule of the eye. The implant will normally be a lens, but may instead be a bung or plug for occluding an opening made in the capsule. The groove may be a continuous groove around the periphery of the implant, or there may be a series of individual spaced-apart grooves formed as projections protruding from the periphery. Instead of a single groove, a pair of axially spaced-apart grooves may be provided, which engage with respective capsulotomies formed in an anterior and a posterior part of the capsule.

  • Publication number: 20040249455
    Abstract: A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly within the capsular bag and lying against the posterior capsule. The periphery of the first optic contains a plurality of generally T-shaped haptics. The overall diameter of the first optic is slightly smaller than the capsular bag. The second optic is located anteriorly to the first optic outside of the capsular bag and is of a positive power. The peripheral edge of the second optic contains a plurality of generally T-shaped haptics and the second optic is slightly larger in overall diameter that the first optic. The haptics 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 and corresponding shrinkage of the capsular bag.

  • Publication number: 20040249456
    Abstract: A flexible accommodating intraocular lens having anteriorly and posteriorly movable extended portions, such as T-shaped haptics, extending from a central solid biconvex optic to be implanted within a natural capsular bag of a human eye with the extended portions positioned between an anterior capsular rim and a posterior capsule of the bag, whereby during a post-operative healing period, fibrosis occurs about the extended portions to fixate the lens in the bag in a manner such that subsequent natural contraction and relaxation of the ciliary muscle moves the optic to provide vision accommodation. A surface of the optic is a toric surface.

  • Publication number: 20040181279
    Abstract: An accommodating lens assembly having an optical axis and being adapted to be implanted in a posterior chamber of an eye having a capsular unit located therein. The assembly comprises a rigid haptics element adapted to secure the assembly within the posterior chamber outside said capsular unit. The element is transparent at least in a region around the axis. The assembly further comprises a resilient body adapted to operate as a lens having a curved surface when pressed up against the region of the haptics element by an axial force applied thereto by the capsular unit. A change in this force causes a change in a radius of curvature for the curved surface.

  • Publication number: 20040111151
    Abstract: An accommodating IOL comprises an optic adapted to focus light toward a retina of an eye, and a movement assembly coupled to the eye to provide effective accommodating movement, preferably axial movement, of the optic. At least a portion of the movement assembly is made from a material that is less stiff and/or more resilient than the material used to make the optic. Optionally, an outer ring or support portion made at least partially from either a relatively stiff material such as the material used in the optic or a relatively resilient material such as the material used in the movement assembly is also provided.
