Definitions
- the natural human lens effects accommodation, as between near and far vision, by ciliary muscle contraction and relaxation under brain control to dispose the lens in varying thicknesses at various locations along the axis of the eye.
- the present invention provides improved, increased posterior vaulting of a lens optic by elongation of haptics disposed oppositely of the optic, while reducing the optic dimension in the longitudinal direction of the haptics.
- the present invention provides an intraocular accommodating lens wherein an asymmetrical optic is of substantially greater dimension transversely of the longitudinal direction of haptics extending therefrom, and is of lesser dimension in the longitudinal direction of the haptics. With each haptic elongated to extend between the capsular bag equator and the optic, increased posterior vaulting of the optic is provided.
- Figure 1 is an elevational view of a preferred form of accommodating lens according to the invention
- Figure 2 is a sectional view of the lens of Figure 1 disposed in an eye, showing the lens optic in a generally anterior position and in a posteriorly vaulted position;
- Figure 3 is an elevational view of another preferred embodiment
- Figure 4 is an elevational view of another embodiment; and Figure 5 is an elevational view of another embodiment wherein a generally annular glare - reducing component is disposed about an optic.
- a preferred embodiment 10 of the accommodating lens of the invention is shown as comprising an optic 12 and haptics 14, 16 extending oppositely therefrom and having loops 18 extending transversely thereof for engagement in the equator or rim of a capsular bag of an eye.
- the lens is shortened in the longitudinal direction of haptics 14, 16 extension and elongated in the transverse direction, and the haptics are elongated in the longitudinal direction. From the geometry of the features and components, including the ciliary muscle 20, the haptics and the optic, it will be understood that the elongated haptics provide increased posterior vaulting of the optic, as indicated in Figure 2.
- the optic thus has a somewhat oval configuration, with flat straight portions 21, 22 hinged to the haptics.
- the lens of the invention provides improved, enhanced accommodation by increased posterior vaulting of the optic, while maintaining a maximal optical zone for accurate vision.
- the optic 12 while relatively wide and enlarged in the direction transverse to the longitudinal direction of the haptics, and relatively short in the longitudinal direction, nevertheless has a full optical zone to provide full optical effect transmitted to the retina of the eye.
- Figure 4 shows a lens with indentations 28 at which are hingedly mounted haptics of generally rectilinear rod-like configuration, the haptics having plate elements 32 hingedly mounted to the optic.
- Figure 4 also illustrates a loop haptic portion 34 extending transversely from an outer edge portion of a haptic 36 to aid in centering the lens within the capsular bag of the natural human lens.
- Figure 5 shows an embodiment wherein haptics are hingedly mounted relative to an optic, and disposed about an optic 36 is a thin, annular transparent or translucent light — transmitting member 40 which reduces edge glare imposed on the retina.
