Description

Title of the invention: Multipurpose intraocular implant TECHNICAL FIELD OF THE INVENTION

[0001] The field of the invention is that of intraocular implants, also called intraocular lenses.

[0002] More specifically, the invention relates to the field of ophthalmic surgery, in particular human surgery.

[0003] The invention finds applications in particular in the treatment of cataracts, as well as the correction of vision defects such as astigmatism for example. STATE OF THE ART

[0004] A cataract is the aging of the lens of the eye, when it loses its transparency and becomes opaque.

[0005] The only known treatment for cataracts is surgery, which uses phacoemulsification, a technique using ultrasound, which consists of removing the opacified lens and replacing it with an intraocular lens, or implant (also abbreviated IOL for "Intra Ocular Lens" in English terminology).

[0006] This surgical operation consists of a small incision in the cornea of the eye, the cataract is then fragmented by ultrasound and then aspirated. At the end of the surgery, an artificial lens is placed, also called an intraocular implant (IOL). The correction of the implant must be calculated in advance, before positioning in the eye.

[0007] An intraocular implant generally comprises a central part called optic, which comprises the lens as such, this part being dedicated to vision, forming an artificial crystalline lens. An intraocular implant further comprises a peripheral part called haptic, generally formed by loops, used to stabilize the intraocular implant in the eye. The shapes of the implants, and in particular of the haptics, can vary, in particular depending on the type of implantation for which they are intended.

[0008] The location in the eye that normally includes the lens is called the capsular bag of the eye. Anterior to the capsular bag, between it and the iris of the eye, is the sulcus of the eye. Behind the capsular bag, forming the periphery of the vitreous body of the eye, is the sclera.

[0009] A first known intraocular implant technique aims to place the implant in the capsular bag, in place of the lens that has been removed. This is the most common technique, preferred when the capsular bag is intact.

[0010] The capsular bag may however in certain cases have been ruptured, or be particu- very fragile.

[0011] According to a second known intraocular implant technique, the implant is placed in the sulcus, or ciliary sulcus, of the eye. This type of intraocular implant is distinguished by its haptics which are longer in order to stabilize the implant in front of the capsular bag, in the sulcus.

[0012] According to a third intraocular implant technique, the implant is fixed to the sclera of the eye. This type of implant has loops generally equipped with anchors allowing the implant to be retained on the sclera, by means of small incisions made in the sclera.

[0013] The known implant types mentioned above are each adapted to different types of implantation (bag, sulcus and scleral). In a limited way, certain types of implants can be used for a different type of implantation than that for which they are intended. For example, an implant for implantation in the sulcus can optionally be implanted in the capsular bag, or fixed to the sclera.

[0014] However, alternative implantation techniques for an implant, i.e., implantation for which it is not normally intended, are particularly complex and impractical. In addition, the curative effect of the implant is generally reduced, which is detrimental to a patient wearing the implant.

[0015] There is therefore a need to provide an intraocular implant that can be used ideally for any type of capsular bag configuration (i.e. whether the capsular bag is intact, damaged or absent), i.e. with the same ease and with the same curative effect as an intraocular implant dedicated to each of the aforementioned implantations.

[0016] Furthermore, there is a need to propose such an intraocular implant which makes it possible to improve refractive stability, and which limits the risk of rotation of the implant (in particular with the aim of better correcting astigmatism), in particular when it is placed in the capsular bag. Statement of the invention

[0017] The present invention aims to remedy all or part of the drawbacks of the state of the art cited above.

[0018] To this end, the invention relates to an intraocular implant, comprising a central optical part and a peripheral haptic part, the haptic part comprising a plurality of loops arranged at the periphery of the optical part, the implant further comprising at least two deployable anchors, the anchors each extending from at least one different loop, each anchor comprising a head, and the implant being configured to be able to adopt: - a stable configuration called retracted, in which the anchors are in a retracted position, in which position the head of each anchor is brought closer to the optical part, and in which configuration the implant is suitable for implantation in the capsular bag of the eye, - a stable configuration called deployed, in which the anchors are in a deployed position, in which position the head of each anchor is away from the optical part, and in which configuration the implant is adapted for implantation by fixation to the sclera by means of the heads of the deployed anchors.

[0019] Thus, the implant being able to take two different stable configurations is versatile, and can be used for implantation in the intact or damaged capsular bag in the retracted stable configuration, and for scleral implantation in the deployed stable configuration, in particular when the capsular bag is non-existent.

[0020] Unlike known techniques, the implant can take different stable geometric configurations, i.e. configurations which are not temporary configurations due in particular to a punctual deformation of the implant. The implant must be actively manipulated at the anchors in order to move from one stable configuration to another. Also unlike known techniques, the stable configurations are specifically dedicated to different types of implantation, and the implant is designed to maintain a stable configuration chosen at the time of implantation in the eye.

[0021] Thanks to these provisions, the implant is versatile and can replace different types of existing implants with a single type of implant, the configuration of which can be chosen according to the needs of a patient. This greatly facilitates the logistics of ophthalmic clinics and hospitals, as well as the preparation for an ophthalmic operation. Indeed, since the equipment is unique, the risk of error in the preparation and progress of an operation is greatly reduced.

[0022] Additionally, manufacturing costs can be reduced by manufacturing a single implant, which is beneficial to healthcare professionals and patients.

[0023] According to a preferred embodiment, in said retracted stable configuration, the head of an anchor in the retracted position and the at least one loop from which said anchor extends are capable of gripping the anterior capsule of the capsular bag of the eye.

[0024] Thus, the anchor, not only plays a role of fixing to the sclera in the deployed configuration, also plays a role of maintaining the implant to the anterior capsule of the capsular bag in the stable retracted configuration.

[0025] In such a configuration, the implant can be fixed in the capsular bag even when the latter is damaged, because the implant can be hooked to the anterior capsule without risk of unwanted displacements in the eye.

[0026] Furthermore, when vision correction is desired, the clamping of the anterior capsule makes it possible to establish a certain position of the implant in the eye, along the axis anterior-posterior optics. This improves the predictability of the implant's position in the eye, and therefore the correction.

[0027] The clamping also makes it possible to avoid rotation of the implant in the eye, which avoids any failure to correct astigmatism, when this is also corrected by the implant.

[0028] Thus, in addition to being particularly versatile, the implant greatly improves vision correction in the retracted configuration, by means of the anchors cooperating with the anterior capsule of the eye.

[0029] According to a preferred embodiment, the plurality of handles comprises two pairs of adjacent handles, each anchor extending from the adjacent handles of the same pair.

[0030] According to a preferred embodiment, each anchor comprises at least one branch extending between the at least one handle from which said anchor extends, and the head of the anchor, said branch having a curved shape, making it possible to keep both retracted and deployed positions stably.

[0031] According to a preferred embodiment, said branch is mechanically connected to said handle from which it extends, as well as to the head of the anchor, respectively by an articulation formed by an elastically deformable portion of reduced thickness compared to the thickness of the branch.

[0032] According to a preferred embodiment, said branch extends from a portion of the handle from which said branch extends, which is located substantially in the middle of the handle between a zone of connection of the handle to the optical part, and a point of the handle distal to the optical part.

[0033] According to a preferred embodiment, the head of an anchor comprises a refined portion mechanically connected to at least one branch of the anchor, and a widened terminal portion, adapted to retain the head of the anchor in a scleral incision, when the implant is fixed to the sclera, i.e. in the deployed stable configuration.

[0034] According to a preferred embodiment, the terminal portion is disc-shaped.

[0035] According to a preferred embodiment, the curved shape is concave, the concavity being directed towards the optical part in each of said stable configurations.

[0036] According to a preferred embodiment, an anchor and the at least one handle from which it extends are formed in a single piece.

[0037] According to a preferred embodiment, the handles have a general shape of a portion of an ellipse.

[0038] According to a preferred embodiment, the anchors are substantially diametrically opposed at the periphery of the optical part.

[0039] According to a preferred embodiment, the haptic part is made of polymer hydrophobic or hydrophilic acrylic. BRIEF DESCRIPTION OF THE FIGURES

DETAILED DESCRIPTION OF THE INVENTION

[0041] The present description is given without limitation, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

[0042] It should be noted, from now on, that the figures are not necessarily to scale.

[0043] Figures 1 to 3 show a sectional view of a human eye 10, in which a 100 intraocular implant is implanted, according to three different types of implantations.

[0044] A human eye comprises, among other things, in an anterior-posterior direction: a cornea 11, an iris 12, a lens (not shown) in a capsular bag 13, and a vitreous body (not shown). The vitreous body is surrounded by the sclera 14, or sclera. On the inside and posterior part of the vitreous body is the retina (not shown).

[0045] As previously described, when the lens is removed or excised, particularly in the case of cataracts, an intraocular implant may be used to replace the lens.

[0046] Also, as previously described, different modes of implantation of a Intraocular implants may be considered, depending on a patient's clinical condition and needs.

[0047] [Fig.l] shows the implant 100 in a conventional implantation in the capsular bag 13.

[0048] [Fig. 2] shows the implant 100 in another implantation, in the capsular bag 13, in a manner similar to the implantation of [Fig. 1], except that the capsular bag is ruptured. In such a configuration, a conventional implant could not be satisfactorily maintained in the capsular bag.

[0049] [Fig. 3] shows the implant 100 in yet another implantation, fixed to the sclera 14.

[0050] The implant 100 is thus a versatile, multi-implantation implant.

[0051] For this purpose, the implant 100 can take two stable configurations, namely a stable configuration called retracted, shown in [Fig.4], and a stable configuration called deployed, shown in [Fig.5].

[0052] The intraocular implant 100, or intraocular lens, comprises a central optical part 110, also called optic 110, and a peripheral haptic part 120, also called haptic 120. The implant 100 is substantially planar, and comprises a plane called the main plane in which the optical part 110 and the haptic part 120 extend.

[0053] The implant 100 may be made by molding or machining a flexible plastic, such as an acrylic polymer. The implant 100 may be hydrophobic or hydrophilic. The implant 100, and in particular its haptic portion 120, is generally flexible and may be deformed manually, in particular during the implantation operation in the eye.

[0054] As can be seen in Figures 1 to 3, the optical part 110 has a contour 111, and comprises inside the contour 111 an optical element 112, or lens. The optical element can serve as a replacement for the crystalline lens, and possibly provide optical correction.

[0055] The optical part 110 is here of substantially circular shape, although it can also be substantially oval, rectangular with rounded edges, etc.

[0056] The optical part 110 is not described in more detail here, the invention being able to be applied to different types of implant (different shapes, sizes, corrections, etc.).

[0057] The haptic part 120 comprises a plurality of haptic elements, i.e. at least two haptic elements. The haptic elements are arranged at the periphery of the optical part 110, more precisely at the periphery of its contour 111.

[0058] Here, the haptic elements are called handles 121, due to their shape, shown in the figures. The handles 121 are in particular closed. However, the invention can also be implemented in the context of an implant where the shape of the handles 121 is different, in particular an open shape, as shown in [Fig.6] (in a retracted configuration only).

[0059] Here, there are four handles 121, however only a minimum number of two handles 121 is necessary for implementing the invention (which, where appropriate, may possibly have a different shape from that shown in the figures).

[0060] In the illustrated preferred embodiment, the four handles 121 are arranged in pairs of adjacent handles, each pair of adjacent handles being the mirror image of the other by central symmetry about the center of the optical portion 110.

[0061] The handles 121 here have a shape substantially of a general shape of a portion of an ellipse (i.e. a truncated ellipse), the handles 121 of one pair of handles being substantially turned towards each other, and away from the handles of the other pair of handles. As can be seen in particular in FIGS. 4 and 5, the implant 100 with the four handles 121 distributed around the periphery of the optical part 110 has a general “butterfly” shape.

[0062] The handles 121 may, however, for example, have a substantially circular shape, and be distributed uniformly around the optical part 110.

[0063] The implant 100 is versatile thanks to the presence of at least two anchors 130 which it comprises and which are deployable.

[0064] The anchors 130 can take a retracted position and a deployed position, and move from one to the other of the positions. Furthermore, each of the two positions is a stable position of the anchors 130, that is to say a position which is maintained by the implant 100 in the absence of external stress. In particular, here the anchors 130 can be bistable.

[0065] The anchors 130 each extend from at least one different handle 121. In the illustrated example, each anchor 130 extends from two different handles 121.

[0066] Thus a first anchor 130a is associated with a first pair of adjacent handles 121a from which it extends, and another second anchor 130b is associated with a second pair of adjacent handles 121b from which it extends, as can be seen in more detail in Figures 4 and 5.

[0067] The anchors 130a and 130b are arranged between the handles 121 of the pair with which they are associated.

[0068] Here, the anchors 130a and 130b are thus arranged in a substantially diametrically opposed manner, at the periphery of the optical part 110.

[0069] An anchor 130 will now be described in more detail, according to a preferred embodiment.

[0070] An anchor 130 comprises at least one branch 131, and a head 132. The branch 131 extends between the at least one handle 121 from which the anchor 130 extends, and the head 132 of the anchor.

[0071] Here, the anchor 130 comprises two branches 131. A first branch 131 extends from a first handle 121 of the pair of adjacent handles with which the anchor 130 is associated, and a second branch 131 extends from a second handle 121 of the pair of adjacent handles with which the anchor 130 is associated. The first and second branches 131 both join the head 132 of the anchor. The first and second branches 131 are thus located on either side of the head 132 of the anchor.

[0072] A branch 131 extends from a handle 121 from a portion 124 of the handle 121 which is located substantially in the middle on the handle 121 between a connection zone 122 of the handle 121 to the optical part 110, and a point 123 of the handle distal to the optical part 110.

[0073] Here, the aforementioned connection zone 122 is the connection zone closest to the other handle 121 of the pair of handles (another connection zone is in fact located opposite said connection zone 122, away from the other handle 121 of the pair of handles), and can be defined as the junction point between a handle 121 and the optical part 110. When the handles 121 are open, there is only one connection zone 122.

[0074] Distal point 123 is understood to mean a point radially furthest from the optical part 110. The portion 124 located in the middle of the handle 121 is defined as an area comprising the points located closer to the middle of the arc defined between the connection area 122 and the distal point 123. Figures 4 and 5 show the middle of such an arc, as well as the portion 124.

[0075] It is however also conceivable that a branch 131 extends from an area located outside the portion 124.

[0076] A branch 131 is connected to the handle 121 from which it extends, as well as to the head 132 of the anchor, by means of an articulation. The articulation allows relative movement of the branch 131 with respect to the handle 121, as well as with respect to the head 132.

[0077] First of all, it is recalled that the optical part of the implant 100 is generally flexible, so that the junction points between a branch 131 and a handle 121, and a branch 131 and a head 132, are also flexible. Thus, the branches 131 are naturally articulated.

[0078] In order to increase the flexibility at these junction points, the joints are formed by a portion of elastically deformable material of reduced thickness compared to the thickness of the branches 131. These thinned zones therefore make it possible to form flexible hinges, facilitating the passage from one to the other of the stable positions.

[0079] Other types of joints can be envisaged, for example by a specific shape, a specific material, or a texture (for example micro-perforated) of these junction points.

[0080] The branches 131 are here of curved shape. The curved shape is concave and here comprises a single concavity, with the concavity directed towards the optical part 110.

[0081] Such a branch shape 131 advantageously makes it possible to obtain bi-stability of the anchors 130, as will be described later.

[0082] The head 132 of an anchor 130 comprises for example a refined portion 133, mechanically connected to the branch(es) 131. In particular, the refined portion 133 is connected to a branch 131 by means of an articulation as described above.

[0083] The refined portion 133 may for example take the shape of a Y, each of the upper branches of which is connected to a branch 131, in the illustrated embodiment. The upper branches of the Y shape define in particular a substantially semi-circular shape, as illustrated in Figures 4 and 5 in particular.

[0084] The head 132 of an anchor 130 also comprises a widened end portion 134. The widened end portion 134 is mechanically connected to the refined portion 133, for example by material bonding. In particular, the end portion 134 may be connected to a foot of the Y shape of the refined portion 133.

[0085] The widened terminal portion 134 extends away from the optical part 110, from the refined portion 133.

[0086] By widened portion is meant a portion of which at least one of its height or its width (the length being defined as the dimension of the alignment of the portion 133 and the terminal portion 134) is greater than the height or the width of the refined portion, respectively.

[0087] Here, for example, the enlarged terminal portion 134 is disc-shaped. Here, the main plane of the disc lies substantially in the main plane of the implant 100.

[0088] The enlarged terminal portion 134 may however have a different shape, such as a triangular shape, harpoon shape, T shape, etc.

[0089] The enlarged terminal portion 134 is thus adapted to retain the head 132 of an anchor 130 in a scleral incision, when the implant 100 is fixed to the sclera.

[0090] As can be seen in [Fig.4] in particular, in the retracted stable configuration, the head 132 of an anchor 130 can be in contact with the periphery of the optical part 110. However, it is not intended that the head 132 be connected by a material connection or otherwise, to the optical part 110, this in order to maintain its mobility to pass from a retracted configuration to a deployed configuration, and vice versa.

[0091] The optical part 110 may comprise recesses 125, for example semi-circular, made at its periphery, opposite the head 132 of the anchors when they are retracted. Advantageously, the recesses 125 substantially define a circle shape with the upper branches of the Y shape of the widened terminal portion 134, as illustrated in FIGS. 4 to 7.

[0092] Now, the operation of the implant 100 will be described, in particular with reference to FIGS. 4 to 7.

[0093] The implant 100 can adopt two stable configurations, as described above.

[0094] In the stable configuration called retracted, the heads 132 of the anchors 130 are in a position close to the optical part 110.

[0095] In particular, the branches 131 of the anchors 130 are directed towards the optical part 110, from the portion 124 of the handles 121. The head 132 of the anchors 130 extends away from the optical part 110 in all circumstances, but is also brought closer to the optical part 110 in the stable retracted configuration.

[0096] The retracted configuration being stable, this position of the anchors 130 is maintained by the implant 100 in the absence of any external stress.

[0097] Preferably, the retracted stable configuration corresponds to the configuration in which the implant 100 is made available to a user. Indeed, this configuration is generally the most used, in particular because it allows two types of implantation (intact or damaged bag) among the most frequent.

[0098] In the retracted stable configuration, the handles 121 allow the implant 100 to be stabilized in the capsular bag or sulcus.

[0099] The heads 132 of the anchors 130 play a complementary stabilizing role.

[0100] In this configuration, the implant 100 is implanted in the capsular bag near the anterior capsule.

[0101] The anchors 130 can then be used to fix the implant 100 to the anterior capsule in order to stabilize it, in particular when the capsular bag is damaged.

[0102] More precisely, the wall of the anterior capsule is pinched between the branches 131 of an anchor 130 and the head 132 of the anchor.

[0103] This is shown in [Fig.7], which shows in broken lines the parts of the implant 100 located behind the anterior capsule, and in solid lines the parts of the implant 100 located in front of the anterior capsule.

[0104] Because the thinned portion 133 of a head 132 is brought closer to the optical part, the anchor 130 forms, in the retracted stable configuration, a clamp of which a first “jaw” is formed by the branches 131 and a second “jaw” is formed by the head 132.

[0105] The anchor 130 is kept fixed to the anterior capsule under the effect of a slight elastic deformation of the anchor 130.

[0106] Thanks to this pinching of the anterior capsule, the implant 100 is also positioned in a determined and determinable manner according to the anterior-posterior direction of the eye.

[0107] The predictability of the position of the implant 100 (effective lens position, ELP, in English terminology) is greatly improved. The resulting refractive stability makes it possible to correctly correct a patient's vision, eliminating, or at least greatly reducing, the risk of over-correction or under-correction.

[0108] In addition, thanks to this pinching of the anterior capsule, the implant 100 is maintained in an angular position around the anterior-posterior optical axis.

[0109] The risk of rotation of the implant 100 around the optical axis is therefore greatly reduced, which greatly reduces the risk of failure to correct astigmatism, when the implant 100 is also used to correct astigmatism.

[0110] Furthermore, when no implantation in the capsular bag is possible (especially if the capsular bag is non-existent) or desired, a scleral implantation can be used. [YES] In the so-called deployed stable configuration, the heads 132 of the anchors 130 are positioned away from the optical part 110.

[0112] In particular, the branches 131 of the anchors 130 are directed away from the optical part 110, from the portion 124 of the handles 121. The head 132 of the anchors 130 extends away from the optical part 110 in all circumstances, and is also away from the optical part 110 in the deployed stable configuration.

[0113] The deployed configuration being stable, this position of the anchors 130 is maintained by the implant 100 in the absence of any external stress.

[0114] In this configuration, the anchors 130 play a primary role in fixing the implant 100 to the sclera of the eye.

[0115] For this, the heads 132 of the anchors 130 are inserted into incisions made in the sclera, the terminal portion 134 enlarged by a head 132 making it possible to retain the heads 132 in the incisions.

[0116] As can be seen in [Fig.5], the span of the implant 100 is greatly increased when the anchors 130 are deployed, which allows the implant 100 to be correctly fixed to the sclera, the distance between the incisions made in the sclera being significantly greater than the width of the capsular bag.

[0117] The stability of the retracted and deployed stable configurations is obtained in particular thanks to the design of the branches 131, which must be slightly elastically deformed when moving from one stable position to the other. Indeed, the total length of the branches 131 is greater than the distance which separates their attachment zones to the handles 121, which requires such elastic deformation when moving from one stable position to the other.

[0118] When moving from a stable retracted configuration to a stable deployed configuration, the angle formed between the branches 131 and the thinned portion 133 of the head 132 (in particular here the “foot” of the Y shape) changes from a significantly acute angle less than 90°, at an obtuse angle significantly greater than 90°.

[0119] In addition, the branches 131 have a slightly curved shape. Thus, in particular, the transition from the deployed stable position to the retracted stable position is prevented by a bracing effect when pressing on the head 132 of an anchor 130. The concavity of the curved part of a branch 131 is, in each of the stable configurations, directed towards the optical part 110.

[0120] It should be noted, however, that in general, only one transition from the retracted stable configuration to the deployed stable configuration (or even no transition depending on the choice of fixation type) is performed, at the time of implantation of the implant 100 in the eye, in which the implant 100 is no longer intended to change configuration once implanted. It is therefore important that the configurations are stable also for this reason, to avoid any change in configuration once the implant 100 is implanted.

[0121] It should be noted that the invention is not limited to the examples described or illustrated.
