    Accommodative intraocular lenses change diopter power of the lens in the eye to adjust for sharp vision from far to near. Examples of such lenses, for example, the AkkoLens Lumina lens, are disclosed in, for example, Alió et al, and in the prior art documents such as Am J Ophthalmol 2016 164:37-48 and J Refract Surg. 34(2): 78-83 and references mentioned therein, and the optical and mechanical principles reported in, for example, but not restricted hereto, in NL2012133, NL201242, EP1871299, EP1932492, US2009062912, W02005084587, US2014074233, WO2014058316, EP2765952, NL2012257278, US2010131955, US2010106245 and NL1029548 and references to other documents made therein, all of which documents are considered to be part of the present document. These lenses will be used in this document to explain the combination of functions of the lens holder. However, the holder can be applied to any kind of intraocular lens comprising at least two optical elements.
    [1] The basic lens holder, the basic embodiment, an embodiment providing measurement of the fixed optical power of the lens, the power of the lens in its resting state, comprises a holder base fitting component and at least one holder lip.
    The holder base is adapted to fit into a holder base fitting component and holder lip is adapted to provide positioning of the lens on the holder.
    The holder provides separation of the optical of any intraocular lens comprising at least two optical elements. Optical lens surfaces, especially hydrophilic intraocular lens surfaces, can stick together especially at higher temperatures, for example heat sterilization temperatures. So, the lens holder comprises at least one separation component to provide separation of the central section of the optical elements.
    [2-3] The holder base fitting component can be a component of any optical testing equipment for, for example, quality control of the optical qualities of the lens. Also, the same holder base fitting component can be a component of any packaging canister.
    [4-5] The holder lip can comprises at least one stopper component adapted to provide stable positioning of the lens on the holder lip, preventing the lens of sliding of the holder in a direction away from the holder base, or, in a direction towards the holder base, or, in case of multiple stopper components, in any direction. Alternatively, the holder lip can comprise at least two holder lip sections of different size separated by a stopper component to provide positioning of lenses of different sizes. The different sizes refer to different thickness of the sections, or, to different width of the sections, or, to different length of the sections, or, to any combination of such different sizes.
    [6-7] The holder lip comprises at least one optical component to provide optical inspection of the lens which component is any opening adapted to provide transmission of at least one light beam of optical testing equipment through both optical elements. Such opening can be a circular opening, or, a slit-like opening, or, an opening of any other shape. The optical component can comprise additional optics to modify the light beam, for example a lens, or, a prism, or, a beam splitter, or, any combination of additional optics depending on the requirements of the optical testing equipment.
    [8] The holder also comprises at least one indicator component to provide indication of lens front side and back side, the anterior and posterior lens surfaces, for example an inscription, preferably a moulded inscription or any other indication visible under the surgical microscope during removal of the lens from the holder before placement in the lens injector.
    [9-11] In an alternative embodiment, an embodiment to measure accommodative power of the lens also, the holder can also comprises at least two accommodating arm components, also ‘arms’, to provide a variable rate of lateral compression to the haptics of the lens which rate of compression depends on the position of the lens on the holder. Increasing compression will increase the focal power of the lens and decreasing the rate will decrease the focal power. The arms comprise a groove, or, notches, or, any other mechanical structures on the inside to guide the haptics of the accommodating lens. The arms can be designed such that the focal lens of the lens varies in a continuously or, alternative, to vary the focal length in discrete steps. Also, the arms can be designed such that the arms function as a stopper component, as in Fig. 12. The optical component of the holder can be a slitlike opening, or, multiple circular openings, or any other type of openings as required by the optical testing equipment.
    Clearly, the lens holder can be manufactured from certified lens compatible material, generally for example a metal, PMMA, polypropylene by lathing, moulding or 3D printing.

On such holder lip the lens can be positioned over the optical component as required by the optical testing equipment. Such optical components of increasing diameter can be combined in a single, tapering, slit-like opening. Fig 8. Lens holder, in this example comprising two stopper components, with the holder fitted with an accommodating lens as disclosed in, for example, any of the documents NL2012133, NL201242, EP1871299, EP1932492, US2009062912, W02005084587, US2014074233, WO2014058316, EP2765952, NL2012257278, US2010131955, US2010106245 and NL1029548 and related documents. Fig 9. Lens holder, in this example the alternative embodiment which allows measurement of fixed optical power, the power of the lens in resting state as well as the variable power of the lens. In this example with the holder comprising multiple circular optical components, 17, and two accommodating arms, 15, 16, which compress the lens at an increasing rate in lateral direction when the lens is slided, is pushed, from the tip of the lip towards the holder base.

As Fig. 9, with in this example the arms, 19, 20, increasing the lens compression in three discrete steps. Fig 12. As Fig.9, with in this example the arms, 21,22, bending inward near the tip of the holder lip to provide a stopper component function in addition to the accommodating function, with stopper function meaning: providing a barrier to prevent the lens accidentally slipping from the lip, and, illustrating a lens, 23, positioned on the holder as well as the direction of movement, direction of push, to provide varying focus of the lens.
    So, in summary, the present invention discloses a lens holder for an intraocular lens with at least two optical elements with the holder comprising at least one holder base, to fit into a holder base fitting component of, for example, optical testing equipment, or, any packaging, for example a packaging canister, and at least one holder lip to positioning the lens on the holder with the holder providing a combination of components including, firstly, at least one separation component to provide separation of the central, optical, section of the optical elements, and, secondly, at least one optical component to provide optical inspection of the lens, and, thirdly, at least one indicator component to provide indication of lens position on the holder. The holder base fitting component can be component of any optical testing equipment, or, a component of any packaging. The holder lip comprises at least one stopper component to provide stable, meaning: non-sliding, positioning of 5 the lens on the holder lip. The holder lip can comprise at least two holder lip sections of different size adapted to provide positioning of lenses of different sizes. The holder lip comprises at least one optical component adapted to provide optical inspection of the lens which optical component is an opening to provide transmission of at least one light beam of optical testing equipment through both optical elements. The optical component can comprise additional optics to modify the light beam. The holder comprises at least one indicator component to provide indication of front side and back side of the lens.
    In an alternative embodiment the holder also comprises at least two accommodating arms to provide lateral compression to the haptics of the lens, resulting in increase of focus, by sliding the lens along the holder lip. The arms can be designed to vary the focus continuously, or, alternatively, to vary the focus in discrete steps.
