Definitions

  • the present disclosure relates generally to a refractive intraocular implant for placement in either the anterior or posterior chamber of an eye.
  • the present disclosure is further directed to a method for treating refractive errors in a patient by anchoring the intraocular lens into the anterior or posterior chamber of the eye.
  • Intraocular implants for the posterior chamber have been designed to treat myopia (nearsightedness), astigmatism, and hyperopia (farsightedness), but are predominantly designed to replace a previously or simultaneously removed crystalline lens (aphakic eye) in a cataract patient.
  • Intraocular lenses are surgically implanted into the aphakic eye in order to take the place of the previously or simultaneously removed natural crystalline lens. These intraocular lenses are implanted into the posterior chamber of the eye to compensate for refractive errors or to create a specific refraction to assist in visual function. Anterior chamber lenses are also available for complicated cases.
  • the anterior chamber of an eye is an area in front of the iris and behind the cornea.
  • the iris acts as a divider between the anterior chamber and the posterior chamber with the iris constricting and expanding an aperture (pupil) to affect the amount of light captured by the eye.
  • Intraocular lenses have not been predominately designed for the phakic eye (crystalline lens not removed) in the anterior chamber of eye as certain difficulties have been associated with implanting in the phakic eye. Such difficulties include the fact that the phakic eye is a substantially more reactive environment than the aphakic eye. Inflammatory reactions tend to be greater in the anterior chamber of the phakic eye. Such damage may include uveitis hyphemia glaucoma (UGH) syndrome, cataracts, pain, corneal edema, progressive endothelial cell loss, and discomfort.
  • UDH uveitis hyphemia glaucoma
  • Some of these effects may be due to poor lens design or may be due to the presence of the natural crystalline lens in the phakic eye crowding the anterior chamber.
  • the phakic eye has a shallower anterior chamber than the aphakic eye, and the iris is in broad posterior contact with the natural crystalline lens. Therefore, if an inflammatory reaction occurs in the phakic eye, there can be adherence of the iris to an anterior surface of the intraocular lens.
  • intraocular lens of the present disclosure may be appropriate for implantations of a primary lens to be used after cataract extraction for optical correction of the eye.
  • the disclosed intraocular lens has at least three angled fixation haptics that support any type of optic body including a negative, positive, astigmatic, or multifocal power lens to correct refractive errors resulting from conditions such as myopia, hyperopia, presbyopia, astigmatism or previous surgery.
  • the haptic design precludes necrosis of angle tissue and does not distort the iris's architecture.
  • the disclosed intraocular lens includes a refractive lens having a front surface and a back surface, and at least three haptics for positioning into the anatomic or iridocorneal angle of the eye.
  • the distal end of each haptic includes a contact pad for engaging the anatomic angle, the width or radius of the contact pad being greater than that of the haptic.
  • the haptic is curved in both a horizontal and vertical direction, such that the haptic slopes downward in a curved or spiral shape.
  • three haptics are positioned away from the lens such that the center of each contact pad at the distal end of each haptic forms an end to an imaginary equilateral triangle.
  • the refractive ocular lens is centered on the eye.
  • the sloped nature of the haptics ensures that the refractive lens is suspended over the eye, creating a vault between the eye and the refractive lens.
  • the vertical and horizontal curvature of the haptics, as well as the positioning of the contact pads provides both columnar and cantilever support, ensuring that the refractive lens will not rotate in the eye, even when external pressure is applied.
  • the refractive lens is supported by the anatomic angle, it does not require sutures to anchor the lens to the eye, and therefore is easier to implant as well as extract (if needed).
  • the large footprint of the contact pads ensures that that the contact pads do not adhere to the anatomic angle structures, thus avoiding intraocular damage.

  • a refractive anterior chamber ocular implant 1 having three haptics 11, 11 ', 11" being integral or attached to the refracting lens 14.
  • the lens 14 When implanted into the anterior chamber 16 of a phakic eye 18, the lens 14 is positioned and maintained by the haptics 1 1, 11 ', 11" to prevent contact between it and other anatomical bodies such as the anatomical crystalline lens or other intraocular implant 20, the iris 22, and the corneal endothelium 24 (Fig. 3A).
  • the optic lens 14 is in a plane perpendicular to the optic axis 4 of the eye 18, and the three points of contact B, C, D of the haptic 11, 11 ', 11" are distributed on the circumference of the iridocorneal or anatomic angle 31. More particularly, the ends 26, 26', 26" of the respective haptics 11, 11 ', 11" may be configured to situate within the iris plane or angle 31 to prevent irritation of consequential anterior synechia formation, fibrosis and anisocoria.
  • the implant 1 may be implanted into an individual that either has no crystalline lens 20 or pseudophake (surgically implanted lens to replace crystalline lens), as both the lens and capsule may have been removed, such as through a surgery, i.e. intracapsular cataract extraction (ICCE).
  • ICCE intracapsular cataract extraction
  • the intraocular lens 1 is shown in Fig. 3B in use positioned within the capsular bay (aperture left from crystalline lens removal) of the posterior chamber or posterior chamber configuration.
  • the lens 14 may be concave, convex, aspheric, multi-order diffractive, planar, or any combination thereof, in order to achieve the desired degree of corrective refraction.
  • the optical portion of lens 14, may be fabricated from compounds such as silicone polymer, HEMA, acrylic, polymethylmethacrylate (PMMA), polyimide, hydrogel (formed from a certain percentage of water).
  • the artificial refracting lens 14 of the present invention may be foldable (elastic), rigid, or a combination, depending upon the particular selected composition of the lens.
  • the lens 14 may be folded and inserted into a cartridge to be injected into the anterior chamber. After insertion of the implant 1, the flexible lens 14 may be released and recover to its initial shape.
  • the refracting lens 14 of the inventive implant has a lens shape with two surfaces, a front and a back surface 30, 32, such that the combined refractive powers of the two surfaces provides the desired degree of refraction.
  • Lenses 14 having at least one convex surface are typically employed to correct hyperopia.
  • Lenses 14 having at least one concave surface are typically employed to correct myopia.
  • Lenses 14 may have astigmatic correction on either surface.
  • the lens 14 may have a diameter between 5.0 mm and 7.0 mm, preferably at 6.0 mm.
  • the implant surfaces 30, 32 may be coated with a biocompatible polysaccharide medicament. Other compounds well known to those skilled in the art may also be used in fabricating the anterior chamber ocular implant employed in this invention.
  • the haptics 11, 11 ', 11" slope downward, preferably in a curved, parabolic, or spiral shape, suspending the lens 14 in the anterior chamber 16 of the eye 18 at a vault V between the range of 0.6 mm to 1.0 mm, preferably 0.8 mm. This configuration prevents contact of the refracting lens 14 with the natural crystalline lens 20 or iris 22, and prevents pupillary occlusion.
  • the vault V is measured in relation to a flat bottom surface 40, 40, 40" of respective contact pads, duct plate, or footplates 34, 34', 34" and the back surface 32 of the optic 14, when the implant 1 is in a resting position or implanted in the eye 18.

  • the haptics 11, 11 ', 11" are designed having one or more extension pad or contact pads 34, 34', 34" that radially extend or curve at angle A from the lens 14 while maintaining uniformity in thickness in a radial direction to anchor the implant 1 in an anatomic or iridocorneal angle 31 of the eye near the scleral spur and beneath Schwalbe's line. It is foreseen that the thickness of the haptics 11, 11 ', 11" may taper towards the contact pads 34, 34', 34". The thickness of the optic lens 14 will change dependent on refractive power of lens.
