Definitions

  • the present invention relates generally to intraocular lens (IOL) assemblies and particularly to accommodating IOL assemblies with multiple lenses.
  • Natural accommodation in a normal human eye having a normal human crystalline lens involves automatic contraction or constriction and relaxation of the ciliary muscle of the eye (and zonules controlled by the ciliary muscle) by the brain in response to looking at objects at different distances.
  • Ciliary muscle relaxation which is the normal state of the muscle, shapes the human crystalline lens for distant vision.
  • Ciliary muscle contraction shapes the human crystalline lens for near vision.
  • Accommodation The brain-induced change from distant vision to near vision is referred to as accommodation.
  • IOL intraocular lens
  • the IOL assembly includes at least two, preferably rigid, linkage arms, i.e., haptics, each being attached to the optic at a first position on the arm thereof and cooperating with ciliary muscle or the zonules at a second position on the arm. There are at least two pivots, one of which is rotatably attached to each respective haptic intermediate the first and second positions.
  • an accommodating IOL assembly is described in US Patent 6,524,340 to Israel, the disclosure of which is incorporated herein by reference.
  • the haptic does not apply leverage to the artificial lens.
  • one or more leverage arms which connect the haptic to the lens, apply the requisite lever force to the lens to impart accommodating motion to the lens.
  • the leverage arm applies a lever force along a chord inwards of the perimeter of the lens.
  • the leverage arm has a significantly greater "reach" and mechanical advantage than prior art accommodating IOLs, which rely on circumferentially attached haptics to apply leverage to the lens.
  • US Patent 6,767,363 to Bandhauer, et al. describes an accommodating intraocular lens system including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens.
  • the positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more haptic elements.
  • the negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more haptic elements.
  • Each haptic element is formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis.
  • the accommodating intraocular lens system is so designed with specific flexibility characteristics to facilitate axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force.
  • Bandhauer et al. contemplates having the positive optic portion move anteriorly with respect to the negative optic portion, with the negative optic portion either remaining in place or moving posteriorly.
  • the present invention seeks to provide an improved accommodating IOL assembly in which lenses of a double or multiple lens IOL move anteriorly, as is described more in detail hereinbelow.
  • an intraocular lens assembly including a first lens and a second lens, a haptic, and a first leverage arm connecting the first lens to the haptic and a second leverage arm connecting the second lens to the haptic, the first and second lenses being arranged one in front of the other defining an anterior-posterior axis that passes perpendicularly through centers of the first and second lenses, wherein a width of the haptic extends beyond at least one of the first and second lenses in at least one direction parallel to the anterior-posterior axis.
  • the first leverage arm connects a perimeter of the first lens to the haptic and the second leverage arm connects a perimeter of the second lens to the haptic, wherein at least one of the first and second leverage arms is adapted to apply a lever force on its corresponding lens acting generally along a chord inwards of a perimeter of its corresponding lens.
  • the first lens may be a positive lens and the second lens may be a negative lens.
  • an intraocular lens assembly including a first lens and a second lens, a haptic, and a first leverage arm connecting the first lens to the haptic and a second leverage arm connecting the second lens to the haptic, the first and second lenses being arranged one in front of the other defining an anterior-posterior axis that passes perpendicularly through centers of the first and second lenses, wherein the first and second leverage arms are adapted to apply leverage to and move the first and second lenses along the anterior-posterior axis to achieve a combined positive diopter accommodative effect.
  • FIGs. 1, 2 and 3 are simplified pictorial, front view and rear view illustrations, respectively, of an intraocular lens (IOL) assembly, constructed and operative in accordance with an embodiment of the present invention
  • Fig. 4 A is a simplified side view illustration of the IOL assembly of Figs. 1-3, prior to anterior displacement of first and second lenses;
  • Fig. 4B is a simplified side view illustration of the IOL assembly of Figs. 1-3, in which the anterior movement of the first lens equals the anterior movement of the second lens;
  • Fig. 4C is a simplified side view illustration of the IOL assembly of Figs. 1-3, in which the anterior movement of the first lens does not equal the anterior movement of the second lens;
  • Fig. 4D is a simplified side view illustration of the IOL assembly of Figs. 1-3, in which a positive lens moves anteriorly and a negative lens moves posteriorly to give a total accommodative effect of a positive lens;
  • Fig. 4E is a simplified side view illustration of the IOL assembly of Figs. 1-3, in which a pair of negative lenses move posteriorly but still give a total accommodative effect of a positive lens.
  • FIG. 1-4 A illustrate an intraocular lens (IOL) assembly 10 constructed and operative in accordance with an embodiment of the present invention.
  • IOL intraocular lens
  • IOL assembly 10 may include a first lens 12 and a second lens 14, arranged one in front of the other defining an anterior-posterior axis 16 (Fig. 4A) that passes perpendicularly through centers of first and second lenses 12 and 14.
  • One or more first leverage arms 18 (in the illustrated embodiment a pair of first leverage arms 18 are employed) connect first lens 12 to a haptic 20.
  • one or more second leverage arms 22 (in the illustrated embodiment a pair of second leverage arms 22 are employed) connect second lens 14 to haptic 20.
  • two symmetric haptics 20 are employed, shaped generally like portions of a ring. It is understood that this is just one example of a suitably shaped haptic and other sizes and shapes of haptics may be used as well.
  • a width of haptic 20 preferably extends beyond at least one of first and second lenses 12 and 14 in at least one direction parallel to said anterior-posterior axis (this distance being indicated by letter "b").
  • Haptics are clearly defined in the art as the interface elements of the IOL that touch the eye structure ("haptic" is from the Greek word for touch).
  • the leverage arms 18 and 22 do not touch the eye structure and are not the haptics; rather they are attached to the haptics.
  • the attachment point of the leverage arm to the haptic may be flexible, or alternatively, may be rigid with other portions of the leverage arm being flexible.
  • IOL assembly 10 is preferably constructed of a clear, transparent, biologically compatible material, such as but not limited to, polymethylmethacrylate (PMMA), silicone, silicone rubber, collagen, hyaluronic acid (including the sodium, potassium and other salts thereof), hydrogel, such as acrylic or methacrylic hydrogels, e.g., hydroxyethyl methacrylate or methacrylic acid copolymer/partially hydrolyzed poly(2-hydroxyethyl methacrylate) (known as PoIyHEMA), polysulfones, thermolabile materials and other relatively hard or relatively soft and flexible biologically inert optical materials, or any combination of such materials, such as a gel encapsulated in a polymer.
  • IOL assembly 10 may thus be rigid, semi-rigid or foldable, for example.
  • First lens 12 may be a positive lens having a higher diopter positive optic portion, e.g., approximately +20 diopter or greater, such as but not limited to +20 to +60 diopter.
  • Second lens 14 may be a negative lens having a lower diopter negative optic portion, e.g., approximately -10 diopter or less, such as but not limited to -10 to -50 diopter.
  • the invention also encompasses the reverse, wherein the first lens 12 is a negative lens and the second lens 14 is a positive lens, as well both being positive lenses or both being negative lenses.
  • the number of diopters indicates the quantitative change in the distance between the lens and the focal point of light rays entering the lens.
  • a positive diopter value describes a convex lens, while a negative value describes a concave lens.
  • the focal point of light entering a convex lens is beyond the lens, while the focal point of light entering a concave lens is in front of the lens.
  • a positive (convex) lens collects light rays entering the eye and reduces the distance to the focal point.
  • a concave lens diverges light rays entering the eye, moving the true focal point of the light to a point in front of the lens.
  • First and second lenses 12 and 14 may be a combination of biconvex, plano-convex, plano-concave, biconcave, concave-convex (meniscus) or a diffractive-type lens of any shape, depending upon the power required to achieve the appropriate accommodative effects for multi-distance visual imaging and to achieve appropriate central and peripheral thickness for efficient handling and fit within an eye.
  • First and second lenses 12 and 14 may be monofocal or multi-focal lenses, and they may be spherical or aspherical. They may optionally comprise a graded index of refraction, holographic (diffusing) lenses, Fresnel lenses, diffracting lenses, and/or telescopic lenses, for example.
  • Leverage arms 18 and 22 may be configured generally as plates or beams or other shapes. Each pair of leverage arms may be attached to its corresponding lens at two attachment zones 24, which may be generally symmetric about the center of the lens. Each leverage arm may apply a lever force on its corresponding lens acting generally along a chord 26 inward of the perimeter of the lens 12 or 14. The chord 26 preferably connects the two attachment zones 24. Specifically, each leverage arm 18 or 22 acts as a torque or moment transfer device that transfers ciliary muscle relaxation or contraction (designated as distance e in Figs.
  • Each leverage arm 18 or 22 has a significantly greater "reach" and mechanical advantage than prior art accommodating IOLs, which rely on circumferentially attached haptics to apply leverage to the lens.
  • the force transferred by the leverage arms 18 and 22 is generally independent of the boundary condition of haptics 20.
  • both first and second lenses 12 and 14 are adapted to move anteriorly along the anterior-posterior axis 16 to achieve an accommodative effect.
  • This is in contrast to the prior art of US Patent 6,767,363 to Bandhauer, et al., wherein the positive optic portion moves anteriorly with respect to the negative optic portion, with the negative optic portion either remaining in place or moving posteriorly.
  • the present invention does contemplate having a positive lens move anteriorly and a negative lens move posteriorly or two negative lenses moving posteriorly, wherein in all cases the total effect is one of a positive lens, that is, reducing the distance to the focal point.
