Definitions
- Intraocular lens system Intraocular lens system, intraocular lens and ciliary body implant
- the present invention relates to an intraocular lens system, an intraocular lens and a ciliary body implant.
- the invention is therefore particularly in the field of intraocular lenses, in particular biomechanically accommodatable intraocular lenses and ophthalmic surgery.
- Intraocular lenses are known in the prior art, which have a biomechanical accommodation facility, i.e. the refractive effect of the IOL can be changed by exerting mechanical force using muscle tissue and adapted to the desired accommodation.
- IOLs are often implanted in the capsular bag of the eye, since this has a low complication rate compared to other implantation sites, and the necessary surgical techniques are mature, and there are numerous concepts for such biomechanical IOLs.
- the concepts known in the prior art use the naturally triggering force for accommodation, namely the change in diameter of the ciliary body or ciliary muscle, only indirectly. The decisive force transmission takes place rather via the zonular fibers on the elastic capsular bag.
- the elasticity of the capsular bag is very different in different eyes or patients and can change, for example, due to wound healing processes (e.g. fibrosis) after a cataract operation and due to further cell growth (cataract).
- the treatment of the cataract can also change the capsular bag and, in particular, its elasticity. It is therefore often difficult to find a generally valid, well-functioning biomechanical arrangement that is equally suitable for many individual differences in the population and, in addition, the temporal change in the biological material used for the function. To make matters worse, the properties of the biological material used for the function typically cannot be measured prior to cataract surgery, which is why an adaptation to individual circumstances is not possible.
- conventional IOL implants typically have to stretch the original capsular bag in order to reduce / avoid fibrosis, which requires a large implant volume and makes small incision sizes difficult.
- biomechanical, accommodatable IOLs which are implanted outside the capsular bag with direct contact with the ciliary body in the sulcus or in the vicinity of the sulcus.
- the force of the ciliary muscle or ciliary body is converted directly into a mechanical movement or hydraulic deformation in order to produce accommodation of the biomechanical implant.
- These implants typically have contact with the iris or perform relative movements to critical tissue, which, for example, can detach pigments from the iris, which can then, for example, hinder the outflow of eye fluid.
- So-called sulcus IOLs show an increased complication rate due to this and other effects.
- US 2013/226293 A1 describes an electroactive IOL that can be mechanically connected directly to the ciliary muscle.
- WO 2005/084587 A2 discloses a multi-part IOL which has several optical elements that can be pushed one on top of the other to change the refractive effect, the optical elements each being connected to the ciliary muscle of the eye via a support element.
- this object is achieved by an intraocular lens system, a target body implant, an intraocular lens and a method having the features of the respective independent claims.
- Advantageous embodiments are given in the subclaims and in the description.
- the invention in a first aspect, relates to an intraocular lens system for implantation in an eye.
- the intraocular lens system comprises a ciliary body implant with a ciliary magnetic element, the ciliary body implant being implantable in the eye in such a way that the ciliary magnetic element at least partially follows movements of the ciliary muscle or ciliary body.
- the intraocular lens system comprises an intraocular lens which has a lens magnet element.
- the ciliary body implant and the intraocular lens are designed separately from one another and the intraocular lens system is designed to be ner interaction between the ciliary magnetic element and the lens magnet telement in the eye to control a refractive effect of the intraocular lens.
- the invention relates to a ciliary body implant for an intraocular lens system, the ciliary body implant having a ciliary magnetic element and being designed to control a refractive effect of the intraocular lens by means of an interaction between the ciliary magnetic element and a lens magnetic element of an intraocular lens of the intraocular lens system.
- the invention relates to an intraocular lens for an intraocular lens system, the intraocular lens having a lens magnetic element and being designed to control a refractive effect of the intraocular lens by means of an interaction between the lens magnetic element and a ciliary magnetic element of a ciliary body implant of the intraocular lens system.
- the invention in a further aspect, relates to a method for implanting an intraocular lens system into an eye.
- the method comprises implanting an intraocular lens in the eye, the intraocular lens having a lens magnet element, and implanting a ciliary body implant with a ciliary magnetic element in the eye such that the ciliary body implant at least partially follows movements of the ciliary muscle or ciliary body.
- the ciliary body implant and the intraocular lens are designed separately from one another and the intraocular lens system is designed to control a re fractive effect of the intraocular lens by means of an interaction between the ciliary magnetic element and the lens magnetic element in the eye.
- An intraocular lens system in the sense of the described invention is a system which comprises a biomechanically accommodatable intraocular lens (IOL) and one or more further elements for detecting the will to accommodate, such as in particular a ciliary body implant, and for implementing the accommodation of the IOL.
- the intraocular lens system (IOL system) according to the invention is constructed in several parts, the several parts of the IOL system being present as separate parts and in particular being able to be implanted separately from one another in the eye.
- the several parts of the IOL system, in particular the IOL and the ciliary body implant preferably do not require any direct mechanical and / or hydraulic and / or “wired” electrical connection between one another.
- the ciliary body implant is an implant which can be implanted in the eye and at least partially follows the movements of the ciliary body. It is not absolutely necessary for the ciliary body implant to be implanted and / or arranged directly in and / or on the ciliary body. Rather, indirect mechanical contact between the ciliary body implant and the ciliary body of the eye can be sufficient as long as the ciliary body implant at the implanted site at least partially follows the movements of the ciliary body.
- the ciliary body implant preferably fulfills the function of generating a signal from the movements of the ciliary body, which signal indicates the will of accommodation and can be used for the accommodation of the IOL or the eye.
- the ciliary magnetic element is a magnetic element which is integrated into the Ziliarkör perimplantat and / or connected to it and generates a magnetic field. This magnetic field can then preferably be used to provide the signal for the indication of the will to accommodate, in which the ciliary magnetic element at least partially follows the movements of the ciliary body.
- the fact that the ciliary magnetic element at least partially follows the movements of the ciliary body means that a deflection of the ciliary magnetic element or its change in position in the eye does not necessarily have to be of the same amplitude and / or in the same direction as the deflection of the ciliary body, which the Deflection and / or change of position of the ciliary body caused.
- the ciliary magnetic element follows the movements of the ciliary body in such a way that the ciliary magnetic element provides a signal which allows the movement of the ciliary body to be recognized at least qualitatively.
- the signal provided by the ciliary magnetic element such as a change in the magnetic field generated by the ciliary magnetic element, is preferably proportional, preferably directly proportional to the amplitude of the causing movement of the ciliary body.
- the ciliary magnet element is preferably designed as a permanent magnet or comprises one.
- the permanent magnet can comprise a ferromagnetic material, such as a ferrite.
- the IOL is an accommodatable IOL, particularly preferably a biomechanical IOL.
- the eye can accommodate by changing the refractive effect of the IOL in the eye.
- the change The refractive effect can preferably take place in that a mechanical force is exerted on the IOL or at least a part of the IOL.
- the mechanical force can be provided, for example, by the magnetic field generated by the ciliary magnet element or by changing it.
- the lens magnet element is preferably designed as a permanent magnet or comprises one.
- the permanent magnet can comprise a ferromagnetic material, such as a ferrite.
- the lens magnetic element and the ciliary magnetic element are of identical design and, when implanted in an eye, are arranged in such a way that they are polarized opposite to one another, i.e. in opposite directions to one another.
- the interaction between the ciliary magnetic element and the lens magnet element preferably comprises or consists of a magnetic interaction.
- the interaction between the ciliary magnet element and the lens magnet element leads in particular to the fact that a change in the magnetic field generated by the ciliary magnet element (at the position of the lens magnet element) caused by a change in position of the ciliary magnet element causes a force to act on the lens magnet element, which then changes tion of the refractive effect of the IOL and preferably a corresponding accommodation of the eye can be used or this causes.
- the fact that the interaction between the ciliary magnetic element and the lens magnet element controls the refractive effect of the IOL means that a change in the refractive effect of the IOL preferably follows a change in the interaction between the ciliary magnetic element and the lens magnetic element, in particular a change in the magnetic interaction between the Ciliary magnetic element and the lens magnetic element.
- a movement of the ciliary body can preferably be used to control the refractive effect of the IOL and particularly preferably to provide the force for changing the refractive effect of the IOL.
- the invention offers the advantage that the IOL system can only be provided with passive components. In particular, the interaction between See the ciliary magnetic element and the lens magnetic element by means of permanent magnets, so that no active component is required for the IOL system.
- This offers the advantage that no energy store, such as a rechargeable battery and / or a battery, has to be provided and accordingly there is also no need to replace or exchange such an energy store. As a result, the provision of the IOL system can be simplified and / or the required maintenance effort can be reduced.
- the invention also offers the advantage that the IOL system can be implanted in an eye in such a way that there is no direct contact between the IOL system and the iris and / or no relative movement between the IOL system, in particular the ciliary body implant, and critical tissue of the eye required are. In this way, complications can be avoided, as the IOL system does not detach any pigments from the iris and thus does not create any obstacles to the drainage of eye fluid through the IOL system. As a result, the IOL system according to the invention can reduce the complication rate compared to conventional accommodatable IOLs.
- the invention offers the advantage that the accommodatable IOL can be designed in a compact design and, in particular, the IOL can be implanted in the capsular bag and is a preferred embodiment, which also favors a low rate of complications.
- This is also favored by the fact that with an IOL system according to the invention no direct mechanical and / or electrical connection between the ciliary body implant and the IOL is required and accordingly no mechanical connection and no electrical conductors necessarily from the IOL through the capsular bag must be guided to the ciliary body implant. This is advantageous because damage to the capsular bag and any associated complications can be avoided or reduced.
- this offers the advantage that it is sufficient to implant only the IOL in the capsular bag, but there is no need or need to implant the ciliary body implant in the capsular bag. In this way, an incision of the capsular bag required for implantation of the IOL into the capsular bag can be kept small.
- the invention offers the advantage that a power transmission from the ciliary body to the IOL for changing the refractive effect of the IOL and thus for the ac-
- the eye does not necessarily have to be accommodated via the zonular fibers and / or the capsular bag of the eye.
- the invention enables a force transmission through the particular magnetic interaction between the ciliary magnetic element and the lens magnetic element, which is not influenced to a significant extent by (unknown) individual tissue properties of the zonular fibers and / or the capsular bag. In this way, falsifications and / or individual differences in force in the force transmission from the ciliary body to the IOL can be reduced or even avoided.
- the refractive effect of the intraocular lens is preferably controlled in that the interaction between the ciliary magnetic element and the lens magnetic element moves two or more Alvarez plates in the intraocular lens relative to one another.
- two or more Alvarez plates can be integrated into the intraocular lens or the intraocular lens can consist of two or more Alvarez plates.
- the Alvarez panels can be rigid so that they retain their shape unchanged when they are shifted relative to one another.
- the Alvarez panels can be at least partially elastic so that they partially change their shape when the Alvarez panels are shifted against one another.
- the Alvarez plates offer the advantage that they can provide a simple and cost-effective way of controlling the refractive effect in an intraocular lens.
- an intraocular lens can be designed to have a (static) cylindrical effect in addition to or as an alternative to a spherical effect.
- the cylindrical or toroidal effect of the intraocular lens can be adjusted according to an optional embodiment by a relative positioning of the Alvarez plates along a direction perpendicular to the direction of movement or displacement of the Alvarez plates.
- the intraocular lens can be designed in such a way that the cylindrical effect can be set by arranging the Alvarez plates offset relative to one another.
- the relative offset of the Alvarez plates to one another takes place in a direction perpendicular to the displacement direction, along which the Alvarez plates are moved relative to one another to control the (spherical) refractive effect and perpendicular to the optical axis of the intraocular lens. Since a cylindrical accommodation for intraocular lenses is typically not desired, the offset of the Alvarez plates to adjust the cylindrical effect is optionally set before the intraocular lens is inserted and then remains unchanged after the intraocular lens has been inserted or implanted. In other words, the Alvarez panels are optionally not along the offset for adjustment the cylindrical effect movable relative to each other. Such a setting of the cylindrical effect of the Alvarez lenses by means of the relative offset offers the possibility of providing an optional cylindrical effect with standardized Alvarez plates.
- the cylindrical refractive power of the intraocular lens can be provided otherwise, i.e. independently of any offset of the Alvarez plates with respect to one another.
- the intraocular lens can be designed with a further optical element which provides the cylindrical effect.
- This further optical element can be designed separately from the Alvarez plates and also integrated into the intraocular lens.
- the further optical element can consist of a corresponding configuration of the Alvarez plates, which provides the offset-independent cylindrical effect.
- the Alvarez plates can be made, for example, by appropriately shaping the Alvarez plates so that they have a cylindrical refractive effect regardless of the offset and / or by suitable diffractive structuring of one or more Alvarez plates, which then in addition to the variable, spherical effect of the Alvarez- Panels provide a static, cylindrical, diffractive effect.
- the fact that the cylindrical effect is static means that the cylindrical effect remains unchanged when the eye accommodates.
- the provision of the static cylindrical effect can also be provided by a combination of an offset-dependent cylindrical, refractive effect of the Alvarez plates and a further optical element, such as a diffractive structuring.
- An alignment of the cylinder axis of a cylindrical effect of the intraocular lens can optionally be determined by a fixed orientation of the intraocular lens relative to the eye.
- the intraocular lens can be implanted in such a way that the axial position of the cylindrical effect extends along the desired direction.
- the angular position of the direction of displacement along which the Alva rez lenses are moved to control the refractive effect has no influence on the optical effect of the intraocular lens and can therefore be disregarded when choosing the angular position of the intraocular lens during implantation.
- the refractive effect of the intraocular lens is preferably controlled in that the interaction between the ciliary magnetic element and the lens magnetic element changes a shape of a membrane in the intraocular lens.
- This embodiment can be particularly advantageous for liquid-filled lenses in which the geometric arrangement of the liquid and thus the lens shape can be changed by means of the membrane.
- the refractive effect of the intraocular lens can preferably be controlled by the interaction between the ciliary magnetic element and the lens magnetic element changing a distance between two optical components of an optical doublet in the intraocular lens.
- the refractive effect of the intraocular lens can preferably be controlled in that the interaction between the ciliary magnetic element and the lens magnet element changes the shape of the intraocular lens, which can be particularly advantageous for thin and / or flexible lenses.
- other mechanisms can also be used which allow a reliable change in the refractive effect of the lens with little expenditure of force.
- one or more of these possibilities for controlling the refractive effect can be combined with the optional use of Alvarez plates.
- the Alvarez plates can be embedded in a liquid-filled membrane, so that when the eye accommodates, on the one hand the Alvarez plates move relative to one another and, on the other hand, the shape of the liquid-filled membrane changes and both effects together produce the desired change in the reactive effect of the Effect intraocular lens.
- the ciliary body implant can preferably be implanted in the eye in such a way that the ciliary magnetic element is in mechanical contact with the ciliary body and / or with the sulcus.
- the ciliary body implant can be attached directly in the ciliary body and / or positioned in the sulcus and / or near the sulcus. This offers the advantage that mechanical contact between the ciliary body implant and the iris can be avoided in a particularly reliable manner.
- This also offers the advantage that the ciliary magnetic element can particularly reliably follow the movements of the ciliary body without, for example, being adulterated by the zonular fibers and / or the capsular bag.
- the method for implanting the IOL system is preferably carried out in such a way that the ciliary magnetic element is in mechanical contact with the target body and / or with the sulcus.
- the ciliary body implant preferably has a plurality of ciliary magnetic elements which can be arranged at a distance from one another in mechanical contact with the ciliary body and / or with the sulcus. This offers the advantage that an adjacent arrangement of the lens magnetic element with one of the ciliary magnetic elements can be simplified, since precise positioning of a single, specific ciliary magnetic element adjacent to the lens magnetic element and, correspondingly, precise positioning in the circumferential direction of the IOL is not absolutely necessary.

- IOL system implanted intraocular lens system 30
- the longitudinal sectional view of the eye 10 reveals the cornea 12 and the iris 14 of the eye 10, as well as the ciliary body 16 lying behind it, the zonular fibers 18 and the empty capsular bag 22, as well as the place where the natural lens 20 was arranged however, in the embodiment shown, it has already been removed from the eye.
- FIG. 1 is also divided into two parts in the vertical direction, the upper part of the longitudinal sectional view and the cross-sectional view showing the eye 10 in a first accommodated state and the lower part showing the eye 10 in a second accommodated state.
- the state shown in the upper half of the image can represent a disaccommodated state of the eye.
- the first accommodated state is to be regarded as an example of a weakly accommodated state for distant accommodation, while the second accommodated state is regarded as a more strongly accommodated state for near accommodation.
- Figure 1 shows the implanted intraocular lens system 30, which is formed in several parts and a ciliary body implant 32 and an intraocular lens (IOL) 34, wherein the ciliary body implant 32 and the IOL 34 are formed separately from one another.
- IOL intraocular lens
- the ciliary body implant 32 has six ciliary magnetic elements 36, which are elastically connected to one another and are arranged in such a way that the ciliary body implant 32 is designed as an annular structure.
- the ciliary magnetic elements 36 are connected by means of mechanical spring elements 38.
- the elastic connection of the ciliary magnetic elements 36 is configured in such a way that compressing and stretching the ciliary body implant 32 in the radial direction is enabled so that the ciliary body implant 32 can follow the movements of the ciliary body 16 when the eye 10 is accommodated or in a non-accommodated one State passes.
- the ciliary magnet elements 36 are arranged in such a way that all ciliary magnet elements 36 have the same polarity in the radial direction.
- all ciliary magnetic elements can be arranged in such a way that their magnetic south pole points radially inwards and their north pole points outwards.
- the ciliary magnetic elements 36 can also be arranged such that their magnetic north pole points radially inwards and the south pole points radially outwards.
- the ciliary body implant 32 is implanted with direct mechanical contact to the ciliary body 16 in the sulcus of the eye or on the sulcus of the eye outside the capsular bag 22, so that a movement of the ciliary body 16 is transmitted directly to the ciliary body implant 32 and the ciliary body implant accordingly to the movements of the Ciliary body 16 follows a stretching or compressing chen.
- the ciliary body perimplantat 32 can be compressed or stretched by the ciliary body 16 in such a way that the diameter of the ciliary body implant 32 increases or decreases so that the ciliary body implant 32 rests against the inside of the ciliary body 16 or on the sulcus.
- the IOL 34 is arranged within the capsular bag 22 and has a lens body 40 and two extensions or haptics 42.
- a lens magnet element 44 is arranged in each of the two extensions 42.
- the IOL 34 can have only one or more than two extensions or have haptics 42, in each of which one or more lens magnet elements 44 are arranged.
- the lens magnet elements 44 and the ciliary magnet elements 36 are designed as permanent magnets or have one or more permanent magnets.
- the ciliary body implant 32 and the IOL 40 are arranged such that each lens magnetic element 44 is arranged adjacent to a ciliary magnetic element 36 in the radial direction in order to achieve the greatest possible interaction between the lens magnetic element 44 and the adjacent ciliary magnetic element 36.
- the ciliary body implant 36 has a plurality of ciliary magnetic elements 36, in particular more than two ciliary magnetic elements 32, since during implantation this makes the arrangement of the ciliary body implant 32 and the IOL 34 relative to one another such that in each case a ciliary magnet element 36 is arranged adjacent to the respective lens magnet elements 44, and thus the implantation process is simplified.
- the magnetic fields of the respectively adjacent ciliary magnetic elements 36 and lens magnetic elements 44 are aligned opposite to one another, so that they repel one another.
- the IOL system 30 enables force to be transmitted from the ciliary body 16 via the ciliary body implant 32 to the IOL 34.
- the force exerted by the ciliary body 16 on the ciliary body implant 32 is transmitted via a magnetic interaction from the ciliary magnetic elements 36 to the lens magnet 44 of the IOL 34 transmitted, so that the force exerted by the ciliary body 16 acts on the lens magnet elements 44 and these in turn change the refractive effect of the lens body 40 or the IOL 34.
- the implanted IOL system 30 thus offers the possibility of changing the refractive power of the IOL 34 by means of movements of the ciliary body 16 and in this way accommodating the eye.
- the eye 10 is shown in a weakly or disaccommodated state.
- the ciliary muscle 16 is relaxed and the IOL 34 is in the state of distance refractive power or disaccommodation.
- the ciliary body implant 32 is also stretched or relaxed and adapts to the inner diameter of the ciliary body 16 so that the ciliary body implant 32 also has a large diameter (relative to the diameter in the accepted state of the eye).
- the eye 10 is shown in a second accommodated state, with greater accommodation being present in this state than in the upper half of the illustration.
- the ciliary muscle is more tense, as a result of which a radially inwardly acting force is exerted on the ciliary body implant 32 and, via the ciliary body implant 32, on the IOL 34.
- the interaction between the ciliary magnetic elements 36 and the lens magnet elements 44 transfers the force at least partially to the IOL 34, whereby the IOL 34 is compressed in the radial direction and the refractive effect of the IOL 34 is increased so that the eye 10 is more comfortable - modified.
- FIG. 2A shows a schematic representation of a ciliary body implant 32 according to the preferred embodiment shown in FIG.
- the ciliary body implant 32 is shown in a radially compressed or compressed form, for example in the accommodated state.
- the right side shows the ciliary body implant in a relaxed or stretched form, for example in a weakly accommodated state.
- 2A and 2B also show the lens magnetic elements 44 located radially inside the ciliary body implant 32, which are repelled by the adjacent ciliary magnetic elements 36 due to magnetic interaction.
- the lens magnetic elements 44 also follow a radial movement of the ciliary magnetic elements 36 and are pressed radially inward by the ciliary magnetic elements 36 when the ciliary body implant 32 goes into the compressed state and are pushed radially outward again by a restoring force of the IOL 34 when the ciliary body implant 32 goes back into the stretched state when the eye 10 is relaxed.
- FIG. 2B illustrates the movement of the ciliary body implant 32 and the resulting movement of the lens magnet elements 44 and the resulting exertion of force on the IOL 34 using a superimposed representation of the IOL system in a compressed state (inside) and in a relaxed state (outside).
- FIG. 3 shows an IOL system 30 according to a further preferred embodiment, which has a ciliary body implant 32 with twelve ciliary magnetic elements 36.
- the ciliary magnetic elements 36 are elastically connected to one another by means of mechanical spring elements 38.
- an exact radially adjacent positioning of one of the ciliary magnet elements 36 to the respective lens magnet elements 44 is advantageous.
- Such precise positioning can be achieved during the implantation of the IOL system 30, for example, in that the ciliary body implant 36 is rotated or rotated in the desired orientation around the center of the annular ciliary body implant 32, so that one of the ciliary magnetic elements 36 is adjacent to one another in the radial direction the lens magnet element 44 is positioned.
- ciliary magnetic elements 36 arranged along the circumferential direction also offers the advantage that the requirement for precise relative positioning of a ciliary magnetic element 36 to a respective lens magnetic element 44 is weakened or eliminated entirely, since the magnetic field generated from the entirety of the ciliary magnetic elements 36 is between The individual ciliary magnetic elements 36 are not weakened or only weakened to a very small extent in comparison to positions which directly adjoin a ciliary magnetic element 36.
- FIGS. 4A and 4B show an IOL system 30 according to a preferred embodiment, in which the refractive effect of the IOL can be changed by means of two displaceable Alvarez surfaces 46a and 46b.
- FIG. 4a shows the IOL system 30 in a relaxed state in a schematic longitudinal sectional view (left) and in a schematic cross-sectional view (right), for example when the eye 10 is relaxed and only weakly accommodated, for example in remote accommodation.
- FIG. 4B shows the IOL system 30 in a correspondingly compressed state, for example when the eye is accommodated for the near area.
- the IOL 34 has two Alvarez surfaces 46a and 46b, which are each connected to a lens magnet element 44 via an extension comprising a haptic.
- the extension If no force is exerted by the ciliary body 16 via the ciliary body implant 32 on the IOL 34, the Alvarez surfaces 46a and 46b are pushed radially outward so that the IOL 34 has the lowest refractive power, for example for distant accommodation. Becomes on the other hand, if a force is exerted by the ciliary body 16 via the ciliary body implant 32 on the IOL 34, the Alvarez surfaces 46a and 46b are pushed inwardly one above the other in radial direction, whereby the refractive power of the IOL 34 is increased and near accommodation can be achieved .
- FIGS. 5A and 5B show an IOL system according to a further preferred embodiment, in which the change in the refractive effect is achieved by changing the shape of the IOL 34.
- the IOL 34 is preferably designed as an elastic, liquid-filled lens, or has one.
- the IOL preferably has a membrane by means of which the shape of the liquid-filled lens can be changed.
- the membrane By means of a force exerted by the ciliary body via the ciliary body implant 32 on the IOL 34, the membrane can be deformed in such a way that the IOL is compressed in the radial direction and then its refractive power is increased.
- FIG. 5A shows the IOL system in a relaxed state, in which the IOL has a low refractive effect
- FIG. 5B shows the IOL system in a compressed state, in which the IOL 34 has a high refractive effect.
- FIGS. 6A to 6C show exemplary preferred embodiments of ciliary body implants 32.
- FIG. 6A shows an embodiment in which the ciliary body implant has only one ciliary magnetic element 36 which can be attached to the ciliary body, for example in and / or on the sulcus.
- FIG. 6B shows a ciliary body implant 32 in the shape of a segment of a circle, which has three ciliary magnetic elements 36, which are elastically connected by two mechanical spring elements 38.
- the circular segment-shaped ciliary body implant can for example be arranged in and / or on the sulcus in such a way that the ciliary body implant 32 is in contact with a part of the ciliary body or its inner surface.
- FIG. 6A shows an embodiment in which the ciliary body implant has only one ciliary magnetic element 36 which can be attached to the ciliary body, for example in and / or on the sulcus.
- FIG. 6B shows a ciliary body implant 32 in the shape
- FIG. 6C shows a further preferred embodiment, according to which the ciliary body implant is annular and has sixth ciliary magnetic elements 36 connected via elastic spring elements 38.
- This ring-shaped ciliary body implant 32 can for example be arranged in and / or on the sulcus, so that the ciliary body implant completely surrounds the inner surface of the ciliary body 16.
- FIG. 7 shows a further preferred embodiment of an IOL 34 in a schematic representation.
- the IOL 34 has an inner lens body 40 which extends along the entire length Is surrounded circumferentially by an extension 42 comprising a haptic.
- the extension 42 six lens magnet elements 44 are arranged along the circumferential direction.
- FIGS. 8A to 8C show, in schematic representations, the principle of operation of an intraocular lens based on Alvarez plates 46a and 46b.
- the relative positioning of the Alvarez plates 46a, 46b along the displacement direction 104 leads to a change in the refractive power of the Alvarez plate pair and consequently of the intraocular lens.
- Increasing overlap of the Alvarez plates 46a and 46b leads to an increasing spherical, refractive effect.
- the intraocular lens can be set such that it has a positive refractive effect in the position shown in FIG. 8A, a zero refractive effect in the position shown in FIG. 8B and a negative refractive effect in the position shown in FIG. 8C.
- the Alvarez plates 46a, 46b are formed adjacent to the iris 14 and can optionally be integrated into the capsule bag and / or integrated into another membrane, possibly filled with liquid (not shown).
- FIG. 9 shows the relative position of the cylindrical effect, which is symbolically represented by a cylinder 106. It can be seen that the cylinder axis 106a runs parallel to the displacement direction 104 of the Alvarez plates 46a, 46b. This ensures that when the Alvarez plates 46a, 46b are moved to change the spherical effect, the cylindrical effect remains unchanged.
- the cylindrical effect can be formed alternatively or in addition to a further optical element by offsetting the Alvarez plates 46a, 46b relative to one another perpendicular to the displacement direction 104 and perpendicular to the optical axis 100, i.e. out of the plane of the drawing or into the plane of the drawing.
- This can lead to a different form of the cylindrical effect of the intraocular lens, so that by offsetting the Alvarez plates, the cylindrical effect can be set before the intraocular lens is inserted.
