Abstract

Haptics for accommodating intraocular lens positioned in the sulcus of the eye which haptics comprise at least one appendage which has such a shape that said appendage extends into the sulcus, or, alternatively, which appendage has such a shape such that the appendage tip extends also into the sulcus and the sclera of the eye. The appendage can be fitted with at least one barb to provide firm positioning.

Description

Haptics for intraocular lens with free-form surfaces
The present document discloses novel haptics, comprising at least one appendage, for an intraocular lens of variable optical power, an accommodating intraocular lens, implanted in the sulcus of the eye, meaning: implanted in front of, anterior of, the capsular bag from which the natural lens is removed.
The lens comprises at least one variable-focus lens that includes at least two optical elements of which at least one element is shiftable in a direction perpendicular to the optical axis. Each of the optical elements has at least one free-form optical surface, in addition to any other optical surfaces. The free-form surface has such a shape that the combination of at least two free-form surfaces provides different focusing powers at a different position of at least one of the optical elements relative to the other optical element.
Such intraocular lenses are disclosed in, for example, and not restricted to, with basic designs in US2009062912 and W02005084587, and the same concept, with various adaptations in, for example, US2014074233, WO2014058316, EP2765952, NL2012257278, US2010131955, US2010106245, NL1029548 and related documents. Ample examples of configurations and illustrations of such lenses can be found in said documents. These lenses are fitted with at least one haptic, an anchor, to position the lens construction in the eye and at least one spring assembly adapted to provide translation of movement of driving means of the eye, or of any other driving means, which can be mechanical driving means, into movement of at least one of the optical elements.
The present invention provides and accommodating intraocular lens, adapted to be implanted in the sulcus of an eye of a person, the lens comprising a variable focus lens that includes at least two optical elements of which at least one element is shiftable in a direction perpendicular to the optical axis, each of the optical elements having at least one optical surface, the surfaces having such a shape that the combination of said surfaces provides different focusing powers at a different positions of at least one of the optical elements relative another optical element, a lens construction into which said variable-focus lens is fitted, the lens construction comprising at least one haptic, one anchor to position the lens construction in the eye and at least one spring assembly adapted to provide translation of movement of a part of the eye into movement of at least one of the optical elements, wherein at least one of the haptics comprises at least one appendage, which appendage is adapted to extend into the sulcus of the eye.
This document discloses novel haptic comprising, at least one, appendage for positioning the lens in the eye. Herein the sulcus provides the movement of the eye, which is transferred to the one of the optical elements.
Preferably each of the haptics comprises two appendages.
Preferably the part of the appendage adapted to extend into the sclera of the eye comprises at least one barb adapted to provide firm coupling of said appendage to the sclera of the eye. Herein the sclera provides the movement of the eye, which is transferred to the one of the optical elements.
The appendage can be of the same material as is the lens, for example, both can be made of, relatively flexible, hydrophilic acrylic, or, alternatively, the appendage can be of a different material as is the lens of variable optical power, for example, the lens can be made of hydrophilic acrylic and the appendage can be made of, relatively rigid, PMMA which rigid material is suited for insertion into the sclera of the eye.
The invention further provides a method for implanting a lens of variable optical power into the eye, the lens comprising at least two optical elements of which at least one element is shiftable in a direction perpendicular to the optical axis, each of the optical elements having at least one optical surface and a lens construction into which said lens is fitted, the lens construction comprising at least one haptic, one anchor, to position the lens construction in the eye and at least one spring assembly adapted to provide translation of movement of driving means into movement of at least one of the optical elements, wherein the method includes inserting at least a part of said appendage into the sclera of the eye during the implantation procedure.
Preferably during the insertion of the part of the appendage into the sclera, barbs present on the appendage are connected with the sclera
The method includes positioning of said appendage in the sulcus of the eye during the implantation procedure, or, alternatively, the method can include insertion of said the tip of said appendage in the sclera of the eye during the implantation procedure.
Subsequently the present invention will be elucidated with the help of the drawings, wherein show:
Figure 1: a diagram of a first embodiment of the present invention;
Figure 2: a diagram of a second embodiment; and
Figure 3: a diagram of a third embodiment.
Figure 1 illustrates the general configuration of an accommodating lens, which are also amply illustrated in documents cited above which are to be included in the present document by reference, with, in this example, two optical elements 1,2, haptics including hinges 3, and appendages 4, wherein the appendages 4 only extend into the sulcus of the eye, avoiding the sclera 7.
Figure 2 illustrates a second embodiment with rigid appendages 5, which extend both into the sulcus of the eye and into the sclera 7 of the eye.
Figure 3 illustrates a third embodiment, similar to the second embodiment, wherein the appendages 5 comprise two barbs 6 for firm coupling between the appendages 5 and the sclera 7 of the eye.
