Lens Having Spacers Patents (Class 623/6.15)
  • Patent number: 10667903
    Abstract: A bioanalogic implantable ophthalmic lens (“BIOL”) capable of replacing the natural crystalline lens (NCL) in its various essential functions after the NCL having been removed and BIOL implanted into the posterior eye chamber and placed into the capsular bag vacated from the NCL. At least the posterior surface of the lens has a convex shape and is made from a transparent flexible hydrogel material. At least the anterior and posterior optical surfaces are defined by rotation of one or more conic sections along the main optical axis and the surfaces defined by the rotation will include a plane perpendicular to the axis and conical surface symmetrical by the axis.

  • Patent number: 10531982
    Abstract: An intraocular implant for use in a surgical procedure such as a cataract operation, or in a refractive-lens exchange surgery procedure, has a main portion and a peripheral portion peripheral to the main portion. The main portion is plate-like in shape and may be a lens or a plug for closing an aperture in the capsule of the eye. The implant has two or more lugs extending from the peripheral portion in a direction substantially perpendicular to a plane of the main portion. The lugs extend either from haptics, which protrude from the main portion, or from a short extension of the edge of the main portion. A method for fixing the implant into the eye involves making two or more voids in the capsule wall, offering up the implant to the capsule, so that the lugs lie adjacent to the voids, and inserting the lugs into the voids.

  • Publication number: 20140180407
    Abstract: An accommodating intraocular lens implant includes an anterior floating lens unit, a posterior lens unit, an anterior lens link, a posterior lens link, and an anterior rim link, which comprises an anterior rim jointed element. An anterior rim complex is disposed such that the anterior floating lens unit is movable toward and away from the anterior rim complex, in an anterior-posterior direction. A lever is connected (a) at a first longitudinal site along the lever, to the anterior floating lens unit by the anterior lens link, (b) at a second longitudinal site along the lever, to the anterior rim complex by the anterior rim link, and (c) at a third longitudinal site along the lever, to the posterior lens unit by the posterior lens link. The second site is longitudinally between the first and the third sites along the lever, such that the second site serves as a fulcrum for the lever.

  • Patent number: 7891809
    Abstract: An optical component comprises a transparent network of cells juxtaposed and separated by walls parallel to a surface of the component, each cell being hermetically sealed and comprising at least one substance with an optical property, and all or part of the surface of said component comprises walls less than 100 nm thick. The optical component is thus pixelized by a cell network, the cells being separated by walls which may themselves be pixelized. Such an optical component is particularly useful for making optical elements such as ophthalmic lenses.

  • Publication number: 20100030332
    Abstract: The invention relates to an accommodative lens implant controlled by the ciliary muscle, consisting of at least one or more lenses made of preferably biocompatible material and disposed on a common optical axis, the at least one lens being a component of a flexible, closed implant body that is transparent in the region of the actual lens, is engaged at its outer periphery with the ciliary muscle, and has a main axis that coincides with the visual axis, and in addition at least part of the implant body with the lens or lenses comprises a fluid filling, such that the axial position of the lens or the lens system can be altered by activation of the ciliary muscle, the implant body being inserted in the sulcus of the posterior chamber of the eye or attached to the ciliary muscle.

  • Publication number: 20030204253
    Abstract: A posterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and a pair of integrally formed haptics. The haptics project posteriorly from the optic. A plurality of holes or slots are formed along the edge of the optic and along the length of the haptics. A soft, highly biocompatible material may be placed into the holes or slots by a friction fit or a primary/secondary molding process. Such a construction helps to avoid pupillary blockage, allows for improved aqueous flow around the natural lens and provides a spacer to hold the lens away from the anterior capsular and the iris.

  • Patent number: 6596025
    Abstract: A narrow profile, glare reducing, refractive mono-focal intraocular lens is described that comprises an optic having an anterior surface and a posterior surface and an optical axis. One of the anterior and posterior surfaces is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power that is preferably outside the −5 to +5 diopter range. A transition zone between the two imaging zones preferably has a continuously variable surface curvature that reduces both indirect glare (caused by light refraction) and direct glare (caused by light diffraction) in an individual's eye in which the intraocular lens is implanted. The transition zone surface may alternatively be continuously curved or variably curved to reduce direct glare and indirect glare, respectively. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye.
