Definitions
- Intraocular lenses of the type described herein are used primarily to treat problems of vision in a human eye.
- the image which would normally be directed to a damaged or diseased area of a retina is refocussed to another area of a retina so that vision may be improved.
- a normal eye has two lenses with four refracting surfaces. Both lenses are convergent lenses which tend to focus light rays inward toward an axis of the eye. Greatest refraction takes place at the aii—cornea interface and lesser refraction occurs at the cornea-aqueous humour interface. Refraction again occurs at the aqueous humour-crystalline lens interface and again at the crystalline lens-vitreous humour interface.
- the aqueous humour and vitreous humour have approximately the same refractive index which is slightly below the refractive indices of the cornea and crystalline lens.
- the crystalline lens is composed of the capsule, the cortex and the nucleus, all of these surfaces having different indices of refraction allowing for color correction of incoming wavelengths of light.
- a crystalline lens When a crystalline lens is removed because of occlusion, for example, with cataracts, its function may be replaced by a relatively thick converging lens worn outside of the eye.
- SUBSTITUTE SHEET Preferably in removing the crystalline lens the capsule is held intact to maintain separation between the vitreous humour and the aqueous humour.
- an intraocular lens is surgically positioned in the posterior chamber of the eye behind the iris and in front of the capsule.
- the introacular lens called a pseudophakos
- a haptic which extends outward from the lens and engages the outer wall of the posterior chamber or the sulcus.
- the lens may be attached directly to the iris or the chamber angle or within the cornea by any known means.
- the pseudophakos has the advantage of eliminating the requirement for thick eyeglasses and increasing the field of vision as compared with thick eyeglasses which may be used to replace a removed crystalline lens.
- the achromatic lens will improve the color correction problem and thus improve overall image quality.
- Current intraocular lenses are made of glass, plastics, silicone or hydrogel.
- achromatic lenses The construction of achromatic lenses is a well-known process. Fine controlled forming, molding and grinding, matching spherical and nonspherical concave and convex or planar surfaces on lenses and joining exact opposite surfaces together with bonding material is known in the art.
- Glass such as combined lenses of flint and ground glass chosen for their different refractive indices may be joined together as an achromatic lens or plastics having different indices of refraction may be joined together or may be combined with glass of the desired index of refraction.
- One plastic well known for use in intraocular lenses is methyl methacrylate.
- Other suitable materials are known such as polycarbonate silicone, hydrogel, or glass.
- One basic plastic may be used and impregnated with materials which provide differing indices of refraction in separate lens elements of the achromatic lens. The use of an achromatic lens consisting of two materials of different refractive indices will allow for better color correction than lenses currently described.
- an achromatic intraocular lens for use in the system is made of two optical lens components cemented together to form a doublet.
- the two lenses are preferably made of materials having different refractive indices so that refraction occurs at the interface as well as at the distal and proximal surface of the joined multiple lenses.
- Provided the appropriate degree of magnification or relocation of the image on the retina may be accomplished by the achromatic lens, that lens is the preferred multiple intraocular lens system.
- the present invention describes the use and positioning of achromatic lenses within the posterior and anterior chamber of the eye and describes the use of different forms of achromatic lenses to treat different requirements.
- the present invention provides intraocular achromatic lenses.
- the achromatic lens is positioned in a posterior chamber of an eye.
- the achromatic lens may be positioned in an anterior chamber of the eye.
- the achromatic lens is made of two portions haviirg different refractive indices. Preferably both portions are convergent.
- One portion may be convergent and the other portion may be divergent or both portions may be divergent.
- a divergent achromatic lens may be used, for example, when a normal functional crystalline lens is present or when a pseudophakos has replaced an occluded crystalline lens and wherein it is difficult or unnecessary to remove the pseudophakos or normal crystalline lens.
- the purpose of the achromatic lens of the present invention is the usual improved image quality or improved color correction which also enhances the image quality over current areas.
- Figure 1 is a schematic view of a frontal portion of an eye from which a crystalline lens has been removed and in which an achromatic lens has been placed in the posterior chamber.
- Figure 2 is a similar view of an eye in which an achromatic lens has been replaced in an anterior chamber.
- Figures 3, 4, 5 and 6 are details of differing forms of achromatic lenses.
- Figure 1 shows an achromatic lens 1 having a front lens portion 3 and a rear lens portion 5 joined together along a commonly shaped interface 7. Refraction occurs at the aqueous humour front lens interface 8, at the lens interface 7 and at the aqueous humour rear lens interface 9.
- both lenses are convergent lenses, lens 3 being slightly thicker at its center than at its outer edge 11 and the curvature of surface 3 being slightly greater than the curvature of interface 7.
- a conventional haptic 13 extends outward to engage an outer surface of the posterior chamber 15 between the sulcus 16 and the iris 19.
- Eye 17 has a cornea 18. The greatest refraction in the eye occurs at the cornea-air interface.
- Capsule 20 is shown with a crystalline lens removed. As shown in Figure 2, achromatic lens 21 is positioned in the anterior chamber 22 of eye 17. Haptic 23 extends from the side of the achromatic lens to an outer wall of the anterior chamber just in front of the iris 19.
- Achromatic lens 21 has a similar configuration to the achromatic lens 1 shown in Figure 2.
- an achromatic lens 31 is formed of two convergent lenses 33 and 35 having a common interface 37. Refraction occurs at the outer surface 38, the interface 37 and the planar rear face 39.
- Figure 4 shows an intraocular achromatic lens 41 in which both lenses 43 and 45 are convergent lenses and in which both lenses 43 and 45 are convex-concave lenses.
- lens 41 the curvature of surface 48 is greater than the curvature of interface 47 and the curvature of surface 49 is less than the curvature of interface 47.
- a haptic may be mounted anywhere on the outer surface of the lens and may be mounted at the outer edge of the interface 47.
- the intraocular achromatic lens 51 shown in Figure 5 is similar to lens 1 shown in Figure 1, with the exception that the convex-convex portion 53 is located in the front of the lens and the concave-convex portion 55 is located at the rear of the lens. Refraction occurs at the outer surfaces 58 and 59 and at the interface 57.
- the lenses 53 and 55 are of different indices of refraction.
- a divergent intraocular achromatic lens has two divergent lens portions ⁇ 63 and 65 joined at a planar interface 67. Refraction occurs at the concave surfaces 68 and 69 and at the interface 67.
- Lens 61 shown in Figure 6 may be used in conjunction with an existing crystalline lens or pseudophakos.
- the haptic may be connected to one of the two lens portions 63 or 65 or may be connected at the outer edge of the interface 67.
- the peripheral areas of the lenses are reduced to as small as practical an axial dimension.
- the refracting surfaces of the lenses are emphasized for purposes of illustration and the actual refracting surfaces may be quite different depending on the requirements of individual eyes.
- the refraction is arranged in the example of macular degeneration so that the image projected upon the retina is enlarged so that it covers the retina in areas around the macula.
- the lenses are shown with a substantial axial dimension.
- the axial dimension of the lenses may be reduced.
- the actual desired position of the lens is spaced inward or outward from the iris in the posterior chamber or capsule or in the anterior chamber.
- the preferred axial displacement of the intraocular achromatic lens from the iris allows the normal contraction and expansion which occurs with light variations to control pupillary size.
- a capsule may have been destroyed with attendant failure of separation between the vitreous and aqueous fluid.
- the achromatic lens and the haptic may be designed to support the lens in a rearward position within the eye. Under that circumstance, it is preferable to mount the haptic in the posterior chamber or to otherwise connect the haptic to the sulcus.
