Description

Multipurpose intraocular implant TECHNICAL FIELD OF THE INVENTION [1] The field of the invention is that of intraocular implants, also called intraocular lenses. [2] More specifically, the invention relates to the field of ophthalmic surgery, particularly human. [3] The invention finds applications in particular in the treatment of cataracts, as well as in the correction of vision defects such as astigmatism for example. STATE OF THE ART [4] Cataracts are the aging of the lens of the eye, when it loses its transparency and becomes opaque. [5] The only known treatment for cataracts is surgery, which uses phacoemulsification, a technique using ultrasound, which involves removing the clouded lens and replacing it with an intraocular lens, or implant (also abbreviated IOL for "Intra Ocular Lens" in English terminology). [6] This surgical procedure involves a small incision in the cornea of ​​the eye, the cataract is then fragmented using ultrasound and aspirated. At the end of the surgery, an artificial lens, also called an intraocular lens implant (IOL), is implanted. The implant's correction must be calculated beforehand, prior to its placement in the eye. [7] An intraocular implant generally comprises a central part called the optics, which includes the lens itself; this part is dedicated to vision, forming an artificial crystalline lens. An intraocular implant also includes a peripheral part called the haptics, usually formed by loops, which serve to stabilize the intraocular implant within the eye. The shapes of the implants, and in particular the haptics, can vary, notably depending on the type of implantation for which they are intended. [8] The location in the eye that normally contains the lens is called the capsular bag of the eye. In front of the capsular bag, between the latter and the iris At the base of the eye is the sulcus of the eye. Behind the capsular sac, forming the periphery of the vitreous body of the eye, is the sclera. [9] The first known intraocular lens implant technique involves placing the implant in the capsular bag, in place of the removed lens. This is the most common technique, preferred when the capsular bag is intact.

[0010] However, in some cases the capsular bag may have been ruptured, or be particularly fragile.

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

[0012] According to a third intraocular lens implantation technique, the lens is fixed to the sclera of the eye. This type of lens has loops, usually equipped with anchors, that secure the lens to the sclera through small incisions made in the sclera.

[0013] The known implant types mentioned above are each suited to different implantation sites (capsular bag, sulcus, and sclera). In limited cases, some implant types can be used for implantation sites other than those for which they are intended. For example, an implant designed for sulcus placement can sometimes be implanted in the capsular bag or fixed to the sclera.

[0014] However, alternative implant implantation techniques—that is, implantation for a purpose for which an implant is not normally intended—are particularly complex and impractical. Furthermore, the implant's curative effect is generally reduced, which is detrimental to the patient with the implant.

[0015] There is therefore a need to offer 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), that is, with the same ease and with the same curative effect as an intraocular implant dedicated to each of the aforementioned implantations.

[0016] In addition, there is a need to offer such an intraocular implant that improves refractive stability and limits the risk of implant rotation (particularly for the purpose of better correcting astigmatism), especially when placed in the capsular bag. DESCRIPTION OF THE INVENTION

[0017] The present invention aims to remedy all or part of the drawbacks of the prior art mentioned 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 having 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, so-called retracted configuration, 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 adapted 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 deployed anchor heads.

[0019] Thus, the implant, which can 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, particularly when the capsular bag is non-existent.

[0020] Unlike existing techniques, the implant can assume different stable geometric configurations; these are not temporary configurations due to, for example, a localized deformation of the implant. The implant must be actively manipulated at the anchor points to transition from one stable configuration to another. Also unlike existing techniques, the stable configurations are specifically designed for 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 features, the implant is versatile and can replace various existing implant types with a single implant type, the configuration of which can be chosen according to a patient's needs. This greatly simplifies the logistics for ophthalmic clinics and hospitals, as well as the preparation for a ophthalmic surgery. Indeed, since the equipment is unique, the risk of error in the preparation and execution of an operation is greatly reduced.

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

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

[0024] Thus, the anchor, not only plays a role in fixing to the sclera in the deployed configuration, also plays a role in 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 movement in the eye.

[0026] Furthermore, when vision correction is desired, the anterior capsule's compression helps establish a precise position for the implant within the eye, along the anterior-posterior optical axis. This improves the predictability of the implant's position within the eye, and therefore the accuracy of the correction.

[0027] The clamping also prevents the implant from rotating in the eye, thus avoiding any astigmatism correction defects when the implant also corrects it.

[0028] Thus, in addition to being particularly versatile, the implant greatly improves vision correction in the retracted configuration, by means of 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 arm extending between at least one shackle from which said anchor extends, and the head of the anchor, said arm having a curved shape, enabling it to maintain both the retracted and deployed positions stably.

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

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

[0033] According to a preferred embodiment, the head of an anchor comprises a tapered portion mechanically connected to at least one branch of the anchor, and an enlarged terminal portion, adapted to retain the anchor head in a scleral incision, when the implant is fixed to the sclera, i.e. in the stable deployed 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 loop from which it extends are formed in one 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 opposite to the periphery of the optical part.

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

DETAILED DESCRIPTION OF THE INVENTION

[0041] The present description is given by way of non-limiting attribution, each feature of an embodiment being able to be advantageously combined with any other feature of any other embodiment.

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

[0043] Figures 1 to 3 represent a cross-sectional view of a human eye 10, in which an intraocular implant 100 is implanted, according to three different types of implantation.

[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 inner and posterior part of the vitreous body is the retina (not shown).

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

[0046] Also, as described previously, different methods of implanting an intraocular lens can be considered, depending on the clinical condition and needs of a patient.

[0047] Figure 1 represents implant 100 in a classic implantation in capsular bag 13.

[0048] Figure 2 shows implant 100 in a different implantation configuration, within capsular bag 13, similar to the implantation in Figure 1, except that the capsular bag is ruptured. In such a configuration, a conventional implant could not be satisfactorily retained within the capsular bag.

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

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

[0051] For this purpose, the implant 100 can take two stable configurations, namely a stable configuration called retracted, represented in figure 4, and a stable configuration called deployed, represented in figure 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 includes a plane called the principal plane in which the optical part 110 and the haptic part 120 extend.

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

[0054] As can be seen in Figures 1 to 3, the optical part 110 has a contour 111, and includes within 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 substantially circular in shape, although it can also be substantially oval, rectangular with rounded edges, etc.

[0056] Optical part 110 is not described in more detail here, as the invention can be applied to different types of implants (different shapes, sizes, corrections, etc.).

[0057] The haptic part 120 comprises a plurality of haptic elements, that is, 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 loops 121, due to their shape, as shown in the figures. The loops 121 are specifically closed. However, the invention can also be implemented in an implant where the shape of the loops 121 is different, in particular an open shape, as shown in Figure 6 (in a retracted configuration only).

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

[0060] In the preferred embodiment shown, 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 around the center of the optical part 110.

[0061] The loops 121 here have a shape essentially resembling a portion of an ellipse (i.e., a truncated ellipse), with the loops 121 of one pair of loops facing approximately towards each other and away from the loops of the other pair of loops. As can be seen particularly in Figures 4 and 5, the implant 100, with the four loops 121 distributed around the periphery of the optical part 110, has a general "butterfly" shape.

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

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

[0064] The anchors 130 can assume a retracted position and a deployed position, and move from one position to the other. Furthermore, each of these two positions is a stable position for the anchors 130; that is, a position maintained by the implant 100 in the absence of external stress. Specifically, 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] Anchors 130a and 130b are arranged between the loops 121 of the pair to which they are associated.

[0068] Here, the anchors 130a and 130b are thus arranged in a substantially diametrically opposite 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 limb 131, and a head 132. The limb 131 extends between the at least one cove 121 from which the anchor 130 extends, and the head 132 of the anchor.

[0071] Here, the anchor 130 comprises two arms 131. A first arm 131 extends from a first loop 121 of the pair of adjacent loops to which the anchor 130 is attached, and a second arm 131 extends from a second loop 121 of the pair of adjacent loops to which the anchor 130 is attached. Both the first and second arms 131 join the head 132 of the anchor. The first and second arms 131 are thus located on either side of the head 132 of the anchor.

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

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

[0074] Point 123 distal is defined as the point radially furthest from the optical part 110. Portion 124 located in the middle of the loop 121 is defined as an area comprising the points located closest to the midpoint of the arc defined between the connecting zone 122 and point 123 distal. Figures 4 and 5 show the midpoint of such an arc, as well as portion 124.

[0075] However, it is also conceivable that a branch 131 could extend from an area located outside of 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 a joint. The joint allows a relative movement of branch 131 with respect to handle 121, as well as with respect to head 132.

[0077] First, it should be noted that the optical part of the implant 100 is generally flexible, so the junction points between a limb 131 and a loop 121, and between a limb 131 and a head 132, are also flexible. Thus, the limbs 131 are naturally articulated.

[0078] In order to increase flexibility at these junction points, the joints are formed by a portion of elastically deformable material with a reduced thickness compared to the thickness of the branches 131. These thinned areas thus allow the formation of flexible hinges, facilitating the passage from one to the other of stable positions.

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

[0080] The arms 131 are curved here. 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 allows obtaining a bi-stability of the anchors 130, as will be described later.

[0082] The head 132 of an anchor 130 includes, for example, a tapered portion 133, mechanically connected to the arm or arms 131. In particular, the tapered portion 133 is connected to an arm 131 by means of a joint as described above.

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

[0084] The head 132 of an anchor 130 also includes an enlarged terminal portion 134. The enlarged terminal portion 134 is mechanically connected to the refined portion 133, for example by a material bond. In particular, the terminal portion 134 can be connected to a Y-shaped foot of the refined portion 133.

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

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

[0087] Here, for example, the enlarged terminal portion 134 is disc-shaped. Here, the principal plane of the disc lies substantially within the principal 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 Figure 4 in particular, in the stable retracted 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 bond or otherwise to the optical part 110, in order to retain its mobility to move from a retracted configuration to a deployed configuration, and vice versa.

[0091] The optical part 110 may include recesses 125, for example semi-circular, formed on its periphery, opposite the head 132 of the anchors when they are retracted. Advantageously, the recesses 125 define substantially a circular shape with the upper arms of the Y-shaped end portion 134, as illustrated in Figures 4 to 7.

[0092] Now, the operation of implant 100 will be described, particularly with reference to figures 4 to 7.

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

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

[0095] In particular, the arms 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] With 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 100 implant is made available to a user. Indeed, this configuration is generally the most used, particularly because it allows for two of the most frequent types of implantation (intact or damaged sac).

[0098] In the stable retracted configuration, the loops 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, implant 100 is implanted in the capsular bag near the anterior capsule.

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

[0102] More specifically, 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 Figure 7, which shows in dashed lines the parts of implant 100 located behind the anterior capsule, and in solid lines the parts of implant 100 located in front of the anterior capsule.

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

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

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

[0107] The predictability of the effective lens position (ELP) of the implant 100 is greatly improved. The resulting refractive stability allows for accurate vision correction, eliminating, or at least significantly reducing, the risk of overcorrection or undercorrection.

[0108] Furthermore, thanks to this pinching of the anterior capsule, the implant 100 is maintained in 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] In addition, when no implantation in the capsular bag is possible (particularly if the capsular bag is non-existent) or desired, a scleral implantation may be used.

[0111] In the stable configuration known as deployed, the heads 132 of the anchors 130 are positioned away from the optical part 110.

[0112] In particular, the arms 131 of the anchors 130 are directed away from the optical part 110, from the portion 124 of the loops 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 stable deployed configuration.

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

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

[0115] For this purpose, the heads 132 of the anchors 130 are inserted into incisions made in the sclera, the enlarged terminal portion 134 of a head 132 allowing the heads 132 to be retained in the incisions.

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

[0117] The stability of the retracted and extended stable configurations is achieved in particular through the design of the arms 131, which must be slightly elastically deformed when moving from one stable position to the other. Indeed, the total length of the arms 131 is greater than the distance between their attachment points and the handles 121, thus necessitating this elastic deformation when moving from one stable position to the other.

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

[0119] Furthermore, the arms 131 have a slightly curved shape. Thus, in particular, the transition from the stable deployed position to the stable retracted position is prevented by a bracing effect when pressure is applied to the head 132 of an anchor 130. The concavity of the curved part of an arm 131 is, in each of the stable configurations, directed towards the optical part 110.

[0120] It should be noted, however, that generally, only one transition from the retracted stable configuration to the deployed stable configuration (or no transition at all, depending on the chosen fixation type) occurs during the implantation of the implant 100 in the eye, where the implant 100 is not intended to change configuration once implanted. Therefore, it is important that the configurations be stable for this reason as well, to prevent any configuration changes after the implant 100 is in place.

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