Definitions

  • the present invention relates to the field of ophthalmology and to the use of medical devices in ophthalmologic surgery. More particularly, the present invention relates to an apparatus and method for guiding an implantable lens into the eye.
  • the human crystalline lens is a living transparent structure composed primarily of protein having a thickness of about five millimeters and a diameter of about nine millimeters.
  • the lens is suspended behind the iris by zonula fibers that connect the lens to the ciliary body.
  • a lens capsule surrounds the lens.
  • the front portion of the capsule is generally referred to as the anterior capsule and the back portion is generally referred to as the posterior capsule.
  • the term "cataract" refers to the opacity of the lens of the eye.
  • cataracts There are a variety of types of cataracts and for most cataracts, surgical intervention is required to remove and replace the lens with an artificial intraocular lens.
  • the transparency of the lens depends on the physiochemical state of the lens proteins. These proteins, like the proteins of other organs, are sensitive to changes in the properties of their surrounding fluid. Changes in the concentration of dissolved salts, in the pH, in the enzyme activity, or in the osmotic pressure of the surrounding fluid can alter the properties of the lens proteins. Also, like other organs, changes to the proteins of the lens occur with age.
  • Artificial intraocular lenses generally comprise an optical region and a support, or haptic, to facilitate positioning and centering of the intraocular lens within the eye.
  • Intraocular lenses have been made from a number of different materials. For example, hard lenses have been prepared from polymethylmethacrylate (PMMA) and optical glass while flexible lenses have been prepared from silicone, polyHEMA (polyhydroxyethylmethymethacrylate), acrylics, collagen, and combinations thereof.
  • Flexible lenses have the advantage that they can be folded or otherwise deformed prior to implantation to reduce the overall size of the lens during the artificial lens implantation procedure.
  • the extraction procedure can generally be categorized as intracapsular (i.e., where the lens is removed together with the lens capsule) or extracapsular (such as where a portion of the anterior capsule is circularly removed (capsulorhexis) and the posterior capsule is left intact).
  • intracapsular i.e., where the lens is removed together with the lens capsule
  • extracapsular such as where a portion of the anterior capsule is circularly removed (capsulorhexis) and the posterior capsule is left intact.
  • phacoemulsification is a widely used method for the removal of diseased or damaged natural lens tissue.
  • the phacoemulsification process generally employs a small incision typically of about 2 millimeters (mm) to about 4 mm in length (but potentially as small as 1 mm) through the cornea and a probe is used to ultrasonically break apart and remove the crystalline lens through the capsulorhexis.
  • intraocular lens injectors that have been described in the literature to position a deformable artificial intraocular lens in the eye. These injectors typically use an incision of about 2 mm to about 4 mm, which represents the incision size most frequently used in most phacoemulsification procedures. A larger (about 4 mm to about 5 mm) capsulorhexis incision, also used in phacoemulsification procedures, is used to position the lens without requiring elongation of the incision during the injection process.
  • the leading haptic of an intraocular lens is particularly susceptible to bending or kinking as it is advanced into and through the insertor device. More particularly, the leading haptic may engage an obstruction, such as a constricting portion a containment chamber or passageway of the insertor device during loading of the intraocular lens, causing varying degrees of kinking or misalignment. Further, the trailing haptic may also be damaged by the lens manipulating mechanism of the insertor device or by forceps used by the physician.
  • injector devices have been developed that purportedly provide features that enhance the process of implanting an intraocular lens into the eye. Examples of such devices are disclosed in U.S. Pat. Nos. 4,681,102 to Bartell; 4,702,244 and 4,573,998 to Mazzocco; 5,468,246 to Blake; 5,562,676 to Brady; 5,275,604 to Rheinish; 5,474,562 to Orchowski; 4,919,150 to Stoy; 5,123,905 to Kelman; 5,616,148 to Eagles; and 5,496,328 to Nakajima.
  • these injector devices include a mechanism that manipulates a soft intraocular lens into a shape and orientation appropriate for insertion into the eye, such as by folding or otherwise compressing the intraocular lens into a shape having a smaller cross-sectional area than the original unfolded cross- sectional dimension of the lens.
  • These devices can damage the lens and a supporting haptic, such as by tearing the lens or kinking a haptic, during the deformation process if the lens is not accurately and carefully positioned in the device.
  • many of these devices employ a plunger or push-rod to apply a force on a lens and to push the deformed lens from the device into the eye.
  • the pushing action of the plunger can damage the lens material and haptics before the lens is positioned in the eye.
  • a device for introducing a flexible lens implant, particularly a fragile foldable lens, into the eye without damaging the lens implant there is a need for a device to implant a foldable intraocular lens into the eye without damaging a haptic or the lens during the implantation process.
  • the present invention fulfills these and other needs.
  • the present invention is directed to an apparatus for protecting an implantable lens as the lens is loaded into an insertor device.

  • the guide protects the leading support from unintended distortion or misalignment as the lens is loaded into the insertor device.
  • a guide may also be used to protect a support other than the leading support, such as a trailing support of the lens.
  • the guide is used in combination with a resilient sleeve adapted for use in an insertor device.
  • the sleeve includes a first opening and a second opening with a lumen extending through the sleeve.
  • the size of the first opening is greater than the size of the second opening, and the thickness of a wall of the first opening is thinner than the thickness of a wall of the second opening.
  • the guide has an inner diameter or periphery that is sufficiently large to receive a support of an intraocular lens, and an outer diameter or periphery that is sufficiently small to permit the guide to pass through the first and second openings of the sleeve.
  • a stop mechanism may be provided on the guide, the sleeve, or both the guide and sleeve to prevent unintended slippage between the guide and sleeve during use.
  • the guide has a relatively thin wall and a stiffness that is sufficient to partially straighten a support of an intraocular lens.
  • the wall of the guide typically has a thickness ranging from approximately 0.01 mm to approximately 0.30 mm.

  • a guide in accordance with the principles of the present invention, is advantageously employed to properly guide an intraocular lens so as to prevent damage to the lens when loaded into an insertor device. More particularly, the guide of the present invention prevents unintended bending or kinking of a haptic of the intraocular lens as the lens is loaded into the insertor device.

Guide 230 is removed from the insertor device prior to insertion of the lens 250 into the eye. Guide 230 is employed to protect and/or guide a securing member or support (e.g., haptic) of an intraocular lens as the lens is loaded into an insertor or injector device.

Abstract

L'invention concerne un appareil destiné à protéger un cristallin implantable. L'appareil comprend un guide ou support mobile protégeant un cristallin implantable à mesure qu'on charge le cristallin dans le dispositif d'insertion. Le guide est retiré du dispositif d'insertion après chargement du cristallin et avant l'insertion de celui-ci à l'intérieur de l'oeil. Le guide comprend une structure oblongue présentant une périphérie intérieure de taille suffisante pour recevoir un support ou haptique du cristallin. Le guide présente une paroi relativement mince et une rigidité suffisante pour dresser partiellement le support du cristallin. Le guide protège un support avant contre une distorsion ou un désalignement accidentel à mesure que le cristallin est chargé à l'intérieur du dispositif d'insertion. On peut aussi utiliser un guide pour protéger un support arrière du cristallin. Un manchon souple pouvant être utilisé dans un dispositif d'insertion peut être employé conjointement avec le guide. Le manchon comprend une première ouverture et une seconde ouverture à travers lesquelles s'étend une lumière. Le guide présente une périphérie intérieure suffisamment grande pour recevoir un support du cristallin, et une périphérie extérieure suffisamment petite pour permettre le passage du guide à travers les première et seconde ouvertures du manchon. On a prévu un mécanisme d'arrêt sur le guide, le manchon ou à la fois le guide et le manchon afin d'empêcher le glissement accidentel entre le guide et le manchon pendant l'utilisation. Le guide se compose typiquement d'un matériau non opaque et, lorsqu'on l'utilise avec un manchon, à la fois le guide et le manchon peuvent être faits d'un matériau identique ou similaire.
