Holding device for holding an optical implant on a wall area in the inner space of an eye and optical device with a holding device and an optical implant

Description

[0001] The invention relates to a holding device for holding an optical implant to a wall region in the inner cavity of an eye. A further aspect of the invention relates to an optical device with such a holding device and with an optical implant held on the holding device.

[0002] Various types and models of optical devices are known from the state of the art, which can be designed as intraocular lenses. The intraocular lens is usually sutured into a capsular bag or sulcus (scleral sulcus, scleral sulcus, sulcus sclerae) during implantation, particularly when the intraocular lens cannot be sufficiently securely supported in the eye, for example, by the capsular bag. A primary cause of damage to the capsular bag is a so-called capsular rupture as a result of a surgical complication during cataract surgery; however, diseases or situations are also known that cause detachment of the capsular bag or subluxations. Detachments or subluxations as a result of Marfan syndrome or trauma are merely examples in this context.Intraocular lenses generally consist of an optic that is connected to flexible haptic elements, which not only enables minimally invasive insertion, for example into the capsular bag, but also ensures sufficiently secure centration.

[0003] WO 98 / 10717 A1 describes an artificial intraocular lens with a deformable optical zone for implantation during cataract surgery. The lens comprises a lens and four angular elastic haptic elements connected to the lens. These elements are peripherally separated from each other and arranged in a rotational direction such that, in a folded state, the haptic elements lie in the implantation area without additional manipulation. The haptic elements have notches or holes suitable for suture fixation, for example, in the ciliary sulcus.

[0004] DE 199 25 636 B4 describes an intraocular lens for implantation in the anterior chamber of the eye, consisting of a centrally arranged lens body which is provided at its periphery with haptic elements for fixation at the front of the iris, wherein the haptic elements each have two pincer-like arms extending outwards from the periphery of the lens body, between the ends of which a gap is formed in which the iris can be clamped.

[0005] WO 2014 / 137306 A1, WO 2017 / 116357 A1, WO 2016 / 182520 A1, and WO 2017 / 183359 A1 each disclose holding devices for holding an optical implant to a wall region in the inner cavity of an eye. The holding devices each have at least one holding component by means of which a contact force can be exerted on the wall region, thereby supporting the at least one holding component on the wall region. The holding component has a projection region from which at least one projection element extends, which is designed to penetrate, at least in part, into a wall region tissue of the wall region and / or to exert pressure on the wall region at specific points upon exertion of the contact force.

[0006] The object of the present invention is to provide a holding device and an optical device of the type mentioned at the outset, which can be fixed in the interior of an eye with particularly little effort.

[0007] This object is achieved by a holding device having the features of claim 1 and by an optical device having the features of claim 9. Advantageous embodiments are described in the subclaims.

[0008] A first aspect of the invention relates to a holding device for holding an optical implant to a wall region in the inner cavity of an eye, comprising at least one holding component, by means of which a contact force can be exerted on the wall region and thereby the at least one holding component can be supported on the wall region. The optical implant can, for example, be designed as an intraocular lens, by means of which visual impairments can be compensated with little effort. Furthermore, the optical implant can be designed as a prosthesis, i.e. as an artificial replica of at least part of the eye, so that cosmetic correction is possible using the optical implant. The wall region can directly delimit the inner cavity of the eye, at least in some areas. The wall region can, for example, be a sulcus (also called scleral sulcus) or a capsular bag of the eye.Compared to other areas of the eye, capsular bags are particularly stable and resilient, making them particularly suitable for supporting the at least one retaining component while exerting the contact pressure. The at least one retaining component can be designed for direct support against the wall area. With direct support, any intermediate elements between the retaining component and the wall area can advantageously be omitted, thus enabling a particularly low-effort fixation of the retaining device within the eye cavity.

[0009] According to the invention, the at least one holding component has at least one projection region, from which at least one projection element extends, which is designed to penetrate at least partially into a wall region tissue of the wall region and / or to exert pressure on the wall region at specific points when the contact force is exerted. This is advantageous because it enables particularly low-effort fixing of the holding device to the wall region in the interior of the eye. The projection element, for example, makes it possible to dispense with sewing, i.e., suture fixation of the holding device, thereby enabling particularly low-effort fixing of the holding device in the interior of the eye. The partial penetration into the wall region tissue or the specific point-based exertion of pressure enables simple, low-effort fixing of the holding device.The area-by-area penetration is advantageous because it allows for plastic deformation of the wall area and a positive connection between the holding component and the wall area, which enables particularly reliable fixing and securing of the holding device against twisting (anti-twist protection) in the interior of the eye.

[0010] In the context of the present disclosure, the application of pressure at a specific point can be understood as the application of at least one point load to the wall area. This is advantageous because the point load can achieve particularly high friction between the holding device and the wall area. This can cause a point-like indentation of the wall area, thus achieving a particularly advantageous positional securing of the holding component.

[0011] In the context of the present disclosure, the application of pressure at specific points can also be understood as the application of at least one linear load to the wall area. This is advantageous because the application of the linear load enables a linear pressure distribution to the wall area, which also allows for a particularly advantageous positional securing of the retaining component.

[0012] The at least one projection element can preferably be designed as a point or a hook. This allows for easy penetration into the wall area tissue of the wall area and, additionally or alternatively, for effective, targeted pressure to be exerted on the wall area.

[0013] Alternatively, the at least one projection element can also preferably be designed as a web element. The web element can have a triangular cross-section in a plane running perpendicular to its main direction of extension. This also enables easy penetration into the wall area fabric of the wall area and, additionally or alternatively, an effective, targeted application of pressure to the wall area.

[0014] The holding device can generally be designed to be foldable to facilitate insertion of the holding device into the interior of the eye. After insertion into the interior of the eye, the holding device can be unfolded to secure the holding device in the interior of the eye.

[0015] The invention is based on the finding that, although the partial penetration of at least one projection element into the wall tissue can result in minimal damage to the wall tissue, such damage can be tolerated in order to secure the holding device reliably and with little effort. Furthermore, it is based on the finding that, even by selectively exerting pressure using the at least one projection element, a lower contact force can be sufficient to achieve reliable fastening without the need for suture fixation, even by selectively exerting pressure using the at least one projection element.Holding force can be achieved between the wall area and the projection element.

[0016] According to the invention, the at least one holding component comprises at least two haptic elements by means of which the contact force can be exerted on the wall region, wherein the at least one projection region is arranged on at least one haptic element of the at least two haptic elements. This is advantageous because the at least two haptic elements enable particularly simple centering of the holding component. For this purpose, the at least two haptic elements can be arranged opposite one another, for example in a longitudinal direction of the holding device, thereby enabling simple, central holding of the holding device in the interior of the eye. The at least one projection region can be arranged at a distal end of the respective haptic element.

[0017] The at least one holding component can particularly preferably comprise exactly two haptic elements. As a result, when securing the holding component, in contrast to systems known from the prior art with, for example, four haptic elements, tensions on the eye can be kept particularly low, thereby avoiding unnecessary strain on the eye. If the holding component comprises exactly two haptic elements, these two haptic elements can particularly preferably be aligned point-symmetrically to one another. A point-symmetrical alignment can achieve a particularly uniform, low-tension and thus tissue-protecting load on the wall region. In particular, the point-symmetrical alignment can keep any tissue stretching on the wall region between the two haptic elements particularly low.

[0018] It is also advantageous if all haptic elements each have a projection area, which enables the holding device to be secured against rotation in a particularly simple and effective manner.

[0019] According to the invention, the holding device comprises at least one receiving component, which is connected to the at least two haptic elements and to which the optical implant can be reversibly and detachably fixed. This is advantageous because the optical implant can thereby be particularly easily and non-destructively replaced if necessary, without having to replace the holding device. The holding device can thus remain permanently in the interior of the eye, enabling simple replacement of the optical implant through a particularly gentle, minimally invasive procedure. The receiving component can preferably have a holding frame in which the optical implant can be fixed particularly firmly and securely.

[0020] According to the invention, the at least one receiving component is also designed to expand, under the exertion of the contact force, at least in some regions from a non-use form, in which the holding device can be inserted at least in some regions through the interior of the eye defined by the wall region, into a receiving form in which the optical implant can be fixed to the at least one receiving component. This is advantageous because the receiving component can thus have smaller dimensions in at least one direction of extent, for example in a transverse direction of extent, in the non-use form than in the receiving form. Due to the smaller dimensions in the non-use form, easier insertion of the holding device into the interior of the eye is enabled.Because the receiving component is expanded in its receiving shape compared to its non-use shape, the optical implant can be held securely to the receiving component (in its receiving shape). The ability to expand from the non-use shape to the receiving shape makes the holding device particularly suitable for microincisions.

[0021] In a further advantageous development of the invention, at least one of the at least two haptic elements is elastically deformable when the contact force is exerted. This is advantageous because the at least two haptic elements can thus be pre-tensioned to exert the contact force on the wall region. Due to the elastic deformation of the haptic elements, a permanent application of the contact force is possible using the haptic elements, whereby the holding device can be permanently secured in the interior of the eye.

[0022] In a further advantageous development of the invention, at least one of the at least two haptic elements is curved. This is advantageous because a curved design not only enables particularly simple elastic deformability, but also allows for tissue-friendly cushioning, for example, of impact loads or vibrations. As a result of the application of the contact force, the radius of curvature of the curved haptic element can be reduced, thereby achieving a particularly uniform force flow without any stress peaks in the haptic element.

[0023] In a further advantageous development of the invention, at least one haptic element of the at least two haptic elements is connected to the at least one receiving component at a first end region of the at least one haptic element, and the at least one projection region is arranged at a second end region opposite the first end region. This is advantageous because the at least one haptic element thus has particularly high functionality. On the one hand, the at least one haptic element thus serves to hold the receiving component and, on the other hand, to support it on the wall region. Due to this high functionality of the at least one haptic element, a particularly simple and compact design of the holding device and its low-effort fixing in the interior of the eye without suture fixation are possible.

[0024] In a further advantageous development of the invention, opposite end regions of at least one haptic element of the at least two haptic elements are connected to the receiving component, and at least one central region of the at least one haptic element, arranged between the respective end regions, is spaced from the receiving component, with the at least one projection region being arranged in the at least one central region. This is advantageous because the connection of the at least one haptic element at its opposite end regions creates a particularly stable fixation between the haptic element and the receiving component. Because the projection region is arranged in the central region arranged between the end regions, a particularly uniform load distribution of the contact force is achieved.a force resulting from the contact pressure is transmitted across the end areas, which, for example, allows tensions or torsions within the receiving component to be kept to a minimum.

[0025] In a further advantageous development of the invention, the at least one receiving component is elastically deformable by exerting the contact force by means of the at least two haptic elements. This is advantageous because the receiving component thus has a dual function. The receiving component thus not only serves to reversibly detachably fix the optical implant but also contributes to the application of the contact force.

[0026] In a further advantageous development of the invention, the at least one receiving component comprises at least one clamping area to which the optical implant can be clamped and thus releasably fixed. This is advantageous because the clamping area enables the optical implant to be clamped and thus enables a particularly simple, reversibly releasable fixation of the optical implant to the receiving component.

[0027] In a further advantageous development of the invention, the holding device is designed as a single piece. This is advantageous because it allows for particularly easy handling of the holding device when securing it in the interior of the eye.

[0028] A second aspect of the invention relates to an optical device comprising a holding device according to the first aspect of the invention and an optical implant held on the holding device. Such an optical device can be secured in the interior of the eye with particularly little effort. The features presented in connection with the holding device according to the first aspect of the invention and their advantages apply accordingly to the optical device according to the second aspect of the invention, and vice versa.

[0029] The optical implant can generally be designed to be foldable to facilitate insertion into the intraocular cavity. After insertion into the intraocular cavity, the optical implant can be unfolded to secure it in the intraocular cavity.

[0030] In a further advantageous development of the invention, the optical device is designed as a single piece. This is advantageous because it allows for particularly easy handling of the optical device when securing it in the interior of the eye.

[0031] In a further advantageous development of the invention, the optical implant is reversibly and detachably fixed to the holding device. This is advantageous because the optical implant can be replaced particularly easily and non-destructively if necessary, without having to replace the holding device. The holding device can remain within the eye cavity, so that a particularly small opening or incision in the eye is sufficient to replace the optical implant.

[0032] The features and combinations of features mentioned above in the description as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respective combination specified, but also in other combinations or on their own.

[0033] Further advantages, features and details of the invention emerge from the claims, the following description of preferred embodiments and from the drawings.

[0034] The invention is explained once again below using a specific embodiment. This shows: Fig. 1a-b each show schematic sectional views of a partial area of ​​an eye and respective top views of an optical device which can be supported on a wall area of ​​the eye which delimits the interior of the eye, wherein the optical device in Fig. 1a detached from the wall area and in Fig. 1b is supported on the wall area; Fig. 2a-b each show further schematic sectional views of the partial area of ​​the eye as well as respective top views of a holding device for holding an optical implant, wherein the holding device in Fig. 2a detached from the wall area and in Fig. 2b is supported on the wall area; Fig. 3a-b further schematic sectional views of the partial area of ​​the eye as well as respective top views of a variant of the holding device for holding the optical implant, wherein the holding device in Fig. 3a detached from the wall area and in Fig. 3b is supported on the wall area; Fig. 4a is a schematic plan view of a further variant of the holding device for holding the optical implant, wherein the holding device is shown in a non-use form; Fig. 4b is a schematic side view of the Fig. 4a shown variant of the holding device in its non-use form; Fig. 4c a schematic plan view of the further variant of the holding device for holding the optical implant, wherein the holding device is shown in a receiving form in which the holding device is widened compared to the non-use form and supported on the wall region; and Fig. 4d a schematic plan view of the further variant of the holding device in its receiving form, wherein the optical implant is reversibly detachably fixed to the holding device.

[0035] Fig. 1a und Fig. 1b each show an optical device 80, which comprises a holding device 10 and an optical implant 12 held on the holding device 10. The optical implant 12 is designed here as an intraocular lens.

[0036] The optical device 80 can generally be formed as a single piece. Alternatively, the optical implant 12 can also be reversibly and detachably fixed to the holding device 10, so that the holding device 10 can be provided independently of the optical implant 12 or can be fixed in an inner space I of an eye, as shown in FIG. Fig. 2a bis Fig. 4c can be seen. The holding device 10 can generally be formed in one piece.

[0037] In the Fig. 1a bis Fig. 4c Coordinate systems relating to the optical device 80 and the holding device 10 are specified, which are defined by a longitudinal extension direction x, by a transverse extension direction y and by a vertical extension direction z of the optical device 80 and the holding device 10, respectively.

[0038] Fig. 2a bis Fig. 4c each show the holding device 10 for holding the optical implant 12 on a wall region 14 of the eye in the inner eye space I. The holding device 10 generally comprises a holding component 16, by means of which a contact force F can be exerted on the wall region 14 and thereby the holding component 16 can be supported on the wall region 14. The contact force F is generally exerted on the wall region 14 by means of the holding component 16 when the holding component 16 is in a tensioned state (relative to the wall region 14), i.e. as soon as the holding device 10 is inserted into the inner eye space I and the holding component 16 is in support contact with the wall region 14, as in Fig. 1b , Fig. 2b , Fig. 3b , Fig. 4c und Fig. 4d is recognizable.

[0039] In Fig. 1a , Fig. 2a , Fig. 3a , Fig. 4a und Fig. 4b the holding component 16 is shown in a relaxed state outside the inner eye space I, wherein at least in Fig. 1a , Fig. 2a and Fig. 3a , in which the holding device 10 or the optical device 80 are not yet introduced into the interior of the eye I, it can be seen that the holding component 16 in the relaxed state has a greater extent, at least in the longitudinal direction x, than the wall region 14. In the relaxed state, the holding component 16 projects beyond an inner diameter of the wall region 14 in the longitudinal direction x. Accordingly, two haptic elements 30, 40 of the holding component 16 in their relaxed state project beyond the wall region 14 in the longitudinal direction x, as at least in Fig. 1a , Fig. 2a and Fig. 3a is recognizable.

[0040] The holding component 16 is generally designed to penetrate at least partially into a wall area fabric 15 of the wall area 14 when the contact force F is exerted and additionally or alternatively to exert pressure on the wall area 14 at specific points. For this purpose, the holding component 60 has respective projection areas 32, 42, from which a plurality of projection elements 33, 43 extend, as can be seen from the overview of Fig. 1a bis Fig. 4c can be seen. The projection elements 33 are generally associated with and arranged on the projection region 32. The projection elements 43 are generally associated with and arranged on the projection region 42. The projection elements 33, 43 are designed as respective tips in the present case.

[0041] At least some of the projection elements 33, 43 can also be designed as respective web elements, although this is not further illustrated here. The web elements can have a triangular cross-section in a plane extending perpendicular to their main extension direction. This plane can be spanned by the longitudinal extension direction x and the transverse extension direction y.

[0042] The projection regions 32, 42 are arranged here on the haptic elements 30, 40, by means of which the contact force F can be exerted on the wall region 14 and which each have one of the projection regions 32, 42. The projection region 32 is assigned to the haptic element 30, whereas the projection region 42 is assigned to the haptic element 40.

[0043] The haptic elements 30, 40 are generally elastically deformable under the exertion of the contact force F and are curved in shape.

[0044] The holding device 10 may generally comprise a receiving component 60 which is connected to the haptic elements 30, 40 and to which the optical implant 12 can be reversibly and detachably fixed, as shown in particular in Fig. 2a bis Fig. 4d is recognizable.

[0045] The haptic elements 30, 40 can be connected to the receiving component 60 at a respective first end region 34, 44 and the respective projection regions 32, 42 can be arranged at a respective second end region 36, 46 opposite the first end region 34, 44, as shown for example in Fig. 1a, Fig. 1b , Fig. 2a, Fig. 2b can be seen. The first end region 34 and the second end region 36 are assigned to the first haptic element 30, whereas the first end region 44 and the second end region 46 are assigned to the second haptic element 40.

[0046] Fig. 3a bis Fig. 4d show that the opposing end regions 34, 36 of the first haptic element 30 and the opposing end regions 44, 46 of the second haptic element 40 can also be connected to the receiving component 60. As a result, the haptic elements 30, 40 are connected, so to speak, on both sides to the receiving component 60, whereby the haptic elements 30, 40 have no free ends. A central region 38 of the first haptic element 30 arranged between the respective end regions 34, 36 and a central region 48 arranged between the respective end regions 44, 46 of the second haptic element 40 can be spaced from the receiving component 60. The respective central regions 38, 48 each extend in the longitudinal direction x away from the receiving component 60. The projection region 32 can be arranged on the central region 38, whereas the projection region 42 can be arranged on the central region 48.In other words, the projection region 32 can be associated with the central region 38 of the first haptic element 30 and the projection region 42 can be associated with the central region 48 of the second haptic element 40.

[0047] From the overview of Fig. 4a bis Fig. 4d It can be seen that the receiving component 60 can be deformed by means of the haptic elements 30, 40 when the contact force F is exerted. The receiving component 60 can be designed to deform at least in regions from a Fig. 4a und Fig. 4b shown non-use form 62, in which the holding device 10 can be introduced particularly easily into the inner eye space I, which is at least partially delimited by the wall region 14, in a, in Fig. 4c und Fig. 4d shown receiving form 64, in which the optical implant 12 can be reversibly and detachably fixed to the at least one receiving component 60. Especially from the combination of Fig. 4a with Fig. 4c It can be seen that a corresponding widening of the receiving component 60 can take place during its deformation from the non-use form 62 into the receiving form 64 in the transverse direction y. In this case, an insertion of the holding device 10 into the inner eye space I in the longitudinal direction x can take place through a particularly small opening in the wall region 14, not shown here, especially since the receiving component 60 in the Fig. 4a particularly clearly recognizable non-use form 62 has a smaller extension in the transverse direction y, i.e. in the present case it is narrower than in the Fig. 4c particularly clearly recognizable recording form 64.

[0048] Fig. 2a bis Fig. 4dshow that the receiving component 60, which can generally be designed as a frame or as a frame element, can comprise a plurality of clamping regions 66, to which the optical implant 12 can be clamped and thus releasably fixed. The clamping regions 66 can be designed as respective retaining hooks, to which the optical implant 12 can be clamped. For this purpose, the clamping regions 66 can each encompass the optical implant 12 at least in part.

[0049] To enable particularly simple, low-effort, and above all, statically determined mounting of the optical implant 12 on the receiving component 60, the receiving component 60 can comprise exactly three clamping regions 66, although four clamping regions 66 are shown here. The precisely three clamping regions 66 can generally be arranged in a plane spanned by the longitudinal direction x and the transverse direction y, or in a plane parallel to this plane. The clamping regions 66 can be spaced apart by 120° from one another, thereby enabling particularly precise alignment of the optical implant 12 when it is secured by means of the clamping regions 66.

[0050] In general, the holding device 10 provides a self-fixation system for holding the optical implant 12. The optical implant 12 can generally be designed as a lens, in particular as an intraocular lens. The holding device 10 is designed to be supported on the wall region 14 by exerting the contact force F and is thus secured against rotational movements within the interior of the eye I. The holding device 10 can be fixed in the wall region 14 with the respective projection elements 33, 43 and, for example, can grip the wall region 14, thereby providing a particularly durable attachment.

[0051] In their respective relaxed state, i.e., prior to their insertion into the interior of the eye I or prior to their attachment to the wall region 14, the holding device 10 or the optical device 80 have a greater extent in at least one direction of extent, for example, in the longitudinal direction x, than the wall region 14, which may be, for example, a capsular bag or a sulcus (sulcus sclerae) of the eye. This allows the holding device 10 or the optical device 80 to be clamped relative to the wall region 14, thereby exerting the contact force F on the wall region 14. The holding device 10 enables the optical implant 12 provided by a surgeon to be held securely in position in the interior of the eye I and supported on the wall region 14.

[0052] Both the holding device and the optical device 80 can be inserted in a respective folded state into the eye and thus into the interior of the eye I by means of an injector, without having to make a large opening in the form of a cut in the wall region 14.
