Definitions

  • the innovation relates to the field of suspension systems for intraocular lenses.
  • the present invention provides a suspension system for intraocular lenses comprising an attachment body that attaches to a lens element such that arms protruding from said attachment body compress against equatorial regions of the lens capsule to position optical portions of said lens element upon the visual axis of the eye.
  • Figure 1 is a plan view of an embodiment of the invention unattached to a lens element and in its resting state.
  • Figure 2 is a plan view of the embodiment attached to an optical element in its resting state.
  • Figure 3 is a perspective view of the embodiment in its resting state attached to an optical element shown in cross-section.
  • Figure 4 is a plan view of the embodiment attached to an optical element while in its resting state shown overlaying the perimeter of a lens capsule.
  • Figure 5 is a plan view of the embodiment attached to an optical element while in its compressed state within the confines of a lens capsule.
  • the present invention comprises a suspension system 10.
  • Fig. 1 shows a plan view of the suspension system in isolation.
  • the suspension system 10 comprises an attachment body 12 that is attached at opposed ends to arms 14 and 16 respectively.
  • Fig. 2 shows the suspension system 10 attached to a peripheral portion of optical element 18.
  • the underside 23 (Fig. 3) of the attachment body 12 may be glued to the upper surface 25 of optical element 18, outside of the optical area of optical element 18.
  • Optical center 20 of optical element 18 is located within its geometrical center.
  • Extension 22 is a protrusion of attachment body 12 that extends beyond the region of optical element 18 and has a curved edge 27 to contact the inner surface of a lens capsule 28.
  • Arms 14 and 16 also extend beyond the region of optical element 18 in a symmetric fashion, roughly defining an equatorial plane 24 perpendicular to optical axis 26 as shown in Fig. 3.
  • Extension 22 and arms 14 and 16 are roughly co-planar.
  • Fig. 4 shows a plan view of suspension system 10 attached to optical element 18 while in its resting state overlaying the equatorial plane of hypothetical lens capsule 28.
  • Fig. 5 shows a plan view of suspension system 10 attached to optical element 18 while in its compressed state being circumscribed by lens capsule 28.
  • Fig. 4 shows arms 14 and 16 projecting outwardly from attachment body 12, extending beyond the boundaries of lens capsule 28.
  • Fig. 5 shows arms 14 and 16 compressed to fit within lens capsule 28, showing the ends of arms 14 and 16 extending past mid-line 30 of lens capsule 28. The ends of arms 14 and 16 abut against the circular wall of lens capsule 28, pressing attachment body 12 outwardly from the center of lens capsule 28, thereby forcing extension 22 to press against the opposing wall of lens capsule 28 as shown.
  • a preferred embodiment of the invention embodies arms 14, 16 that form a "C" shaped pattern as shown throughout the displayed drawings; however, these arms can be configured into a wide variety of shapes provided that their ends extend outwardly far enough to abut against the circular wall of the lens capsule on the other side of midline 30 of the lens capsule from the attachment body 12. Also, the endings 32, 34 of arms 14 and 16 may be designed in a variety of fashions, a preferred configuration being a rounded bolus or disc with serrations around its outer rim to increase the frictional adherence to the equatorial circumference of lens capsule 28.
  • the present invention can be adapted to fit within the anterior chamber of the eye, resting in front of the iris, parallel with the iris plane.
  • the circumference of the anterior chamber of the eye is referred to as the "angle" of the eye.
  • hypothetical lens capsule 28 is replaced by the angle of the anterior chamber of the eye.
  • Extension 22 can be shaped to match the anatomical contours of the angle to support optical element 18 upon the visual axis of the eye in front of the iris without actually contacting the iris tissue itself.
  • Extension 22 can be perforated by a plurality of holes to soften its texture to distribute the force it would normally exert upon delicate anatomical structures situated within the angle of the anterior chamber. These holes can be oriented to help regulate the flow of aqueous liquid through the trabecular meshwork that circumscribes the angle of the anterior chamber.
  • the present invention can be made in a customized length to fit bio-metric proportions specific to each recipient eye simply by trimming the length of extension 22 accordingly.
  • the preferred method for affixing attachment body 12 to optical element 18 is through polymerization of similar molecular matrixes common to attachment body 12 and optical element 18, e.g. by adhesive or gluing.
  • the suspension system and lens can be manufactured together as a single component. The final shape of such single piece unit can be modified by either laser energy or mechanical cutting machinery to fit within the eye as required.
  • the invention together with an attached optical element, is to be inserted into a vacant lens capsule within the eye with the use of an injector.
  • resilient materials such as HEMA based acrylic materials are used in the production of intraocular lenses and their suspension systems. These materials are soft enough to be folded or compressed to fit within a cylindrical tip of an injector device.
  • the cylindrical tip is attached to a plunger apparatus that pushes the lens and its suspension system through the cylindrical tip and into place within the eye.
  • the walls of the cylindrical tip have slots running along its length to align the suspension system within the eye and to more easily accommodate the arms 14 and 16 as they slide along its length.

Abstract

La présente invention concerne un système de suspension pour lentilles intraoculaires qui possède un corps de fixation qui se fixe à un élément optique tel qu'une lentille de telle sorte que des bras faisant saillie du le corps de fixation appuient contre des régions équatoriales de la capsule du cristallin pour positionner des parties optiques de l'élément optique sur l'axe visuel de l'œil.
