Abstract
Accommodating intraocular lenses with a combination of variable power lenses including, firstly, a variable lens with cubic surfaces fitted onto two optical elements to vary focal power by lateral shift of the elements and, secondly, a variable lens with spherical lenses fitted onto the same elements to vary focal power by axial shift of the elements. A mechanical construction with hinges provides both the shifts of the elements.
Claims17
An accommodating intraocular lens construction, comprising an optical axis, with the lens construction comprising
- at least two optical elements which elements are mutually coupled by at least one elastic haptic and
- wherein at least one optical element, preferably each optical element, comprises
- at least one optical surface comprising an at least partly cubic function shaped or free-formed shape;
- and
- at least one optical surface comprising an at least partly spherical shape;
- wherein the at least one haptic is configured for co-action with at least one driving means in an eye, wherein the driving means comprise at least one natural driving means and/or artificial driving means;
- and wherein the at least one haptic comprises at least one hinge configured to, upon a shift of said driving means, translate shift of said driving means in the eye into lateral shift and/or axial shift of the at least two optical elements, wherein lateral shift is a shift in a direction perpendicular to the optical axis and wherein axial shift of the optical elements is a shift in a direction along the optical axis.
