    Connector for a two-element intraocular lens
    This document discloses a pin-in-hole connection between two optical elements of an intraocular lens, an intraocular lens of variable optical power, an accommodating intraocular lens, implanted in the eye. Two connection principles are known: firstly, the lens is fully moulded, in, for example, silicon polymer, as in W02004010905, which also, by default, provides the connection between elements, or, secondly, two elements are manufactured separately followed by connection by re-polymerization with the same material, same monomers, as the material of which the optical elements are manufactured, as in, for example, US2009062912.
    The connector to connect at least two optical elements of an intraocular lens which is a pin-in-hole connection comprising at least one pin-in-hole construction. The connector can be a cylinder, or, alternatively, a cylinder comprising a knob on the pin. The connector can be of the same material as the material as the optical elements, or, alternatively, the connector is of a different material as the material as the optical elements. The pin-in-hole construction can comprise at least one washer adapted to separate the at least two optical elements. A method to connect at least two optical elements can comprise manufacturing the two optical elements, followed by hydration, swelling and softening, of only the element comprising the hole, followed by assembly of the two elements, followed by hydration of also the second optical element, or, alternatively, a method to connect at least two optical elements of an intraocular lens can be that the connection of the two elements is provided by manipulation intra-surgically, during surgery, in the eye, following injection of said two elements separately. The said intraocular lens of variable optical power can be a 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 has at least one free-form optical surface, in addition to any other optical surfaces, with the free-form surface with 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 lens comprises 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, with the free-form surface with 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.
    With the Figures: Figure 1 shows the two optical elements, 1,2, and the pin, 3, and hole, 4. In this example the hole only partly transverses the second optical element. Figure 2 shows a cylindrical pin fully transversing the second optical element.
    However, pins can have any shape, including oval, square which can be included in the lens in any direction. Figure 3 shows the preferred embodiment with a pin comprising a knob, 5, for firm connection between the optical elements, and at least one washer to separate the optical elements, 6, which washer can be of a different thickness resulting in different distances of separation of said elements. Such washer can be integrated, attached to, one of the elements. Figures 4 and 5 show such said connection for an accommodative IOL as disclosed in US2009062912 and W02005084587, and the same concept, with various adaptations in, for example, US2014074233, WO2014058316, EP2765952, NL2012257278, US2010131955, US2010106245, NL1029548 and related documents. The lens has two optical elements, 7, 8, a connecting component, 9, to connect the elements to haptics, 10, with a flange for sulcus positioning, 11. In this example a single pin with two knobs, 12, as in Figure 4, or, alternatively, multiple pins with knobs, 13, connect the elements, as in Figure 5. Knobs can be fitted into an extended hole in the X-Y plane (with the Z-plane being the optical axis) to provide for a smooth surface.
    So, in summary, the present document discloses a connector to connect at least two optical elements of an intraocular lens with the connection being a pin-in-hole connection comprising at least one pin-in-hole construction, which connector can have any shape in any direction, which can be a simple cylinder, or, alternatively, a cylinder with at least one knob on the pin, which can be a cylinder which comprises at least two knobs on pin which pin fits into a hole in the two optical elements, and, the connector can be of the same material as the material as the optical elements, or, alternatively, of a different material as the material as the optical elements, and, the connector can comprise at least one washer adapted to separate the at least two optical elements, with a method to connect at least two optical elements with a connector with the method comprising manufacturing the two optical elements, followed by hydration, swelling and softening, of only the element comprising the hole, followed by assembly of the two elements, followed by hydration of also the second optical element, or, alternatively, with the connection of the two elements provided by manipulation of the elements intra-surgically, during surgery, in the eye, following injection of said two elements separately, with the intraocular lens being any lens with multiple elements, including but not restricted to a intraocular lens of variable optical power which is a 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 has at least one free-form optical surface, in addition to any other optical surfaces, with the free-form surface with 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.
