Description

Title of the invention: Intraocular implant Technical field of the invention

[0001] The invention relates to an intraocular implant. The invention is particularly applicable to the treatment of cataracts, but certain embodiments may also be used, for example, to treat aniridia. Technical background

[0002] Fig. 1 schematically shows the structure of a human eye 1. In particular, the cornea 3, the capsular sac 5, the lens 7 and the aqueous humor 9 are referenced.

[0003] A cataract is a partial or total clouding of the lens 7 that threatens long-term vision. It affects more than one in five people over the age of 65 and nearly two out of three after the age of 85. Cataracts are usually treated surgically. As such, it is one of the most common surgical procedures in the world. Nearly 4,700,000 people undergo cataract surgery in Europe each year.

[0004] In the most common version of this procedure, the lens 7 of the eye 1 is removed and then replaced by an intraocular implant, consisting of a converging lens made of artificial biomaterial whose power is adapted to the characteristics of the operated eye. More specifically, cataract surgery consists of incising the capsular bag 5, then injecting an intraocular lens (or "IOL") into it in order to restore the patient's visual acuity.

[0005] However, certain complications of the operation can lead to a rupture of the capsular bag 5, resulting in displacement of the intraocular lens within the vitreous cavity. The surgeon is then unable to continue the procedure. Indeed, in this case, the selected intraocular lens can no longer be used, and the surgeon must then consider a new operation to replace the damaged capsular bag and subsequently implant a new intraocular lens.

[0006] Such a complication, particularly when it occurs during the operation, is a source of anxiety for the patient because they must consider undergoing further ophthalmic surgery. It also represents a loss of time for the surgeon and entails additional costs for the healthcare system, as the ongoing operation must be interrupted and a new surgical protocol implemented at a later date. Furthermore, between the two operations, the patient's visual comfort is significantly impaired.

[0007] Furthermore, it should be noted that dislocation or total absence of the lens can also in- intervene, for example:

[0008] • following diseases of elastic tissue or certain ocular pathologies, which gilize the crystalline-capsular sac-zonule complex, or

[0009] • following a violent contusion.

[0010] To at least partially overcome one or more of these situations, it is necessary to replace the capsular bag 5 with an intraocular implant to then allow an intraocular lens to be positioned therein, in particular to avoid the interruption of an ongoing operation and its subsequent reprogramming.

[0011] A capsule of the human eye's lens for the insertion of intraocular lenses is known from document WO2021016678. This capsule is intended for use in ophthalmic surgery involving complications where the surgeon is unable to implant the intraocular lens conventionally, primarily in cases of surgical, traumatic, or disease-related injuries that cause degradation or fragility of this structure. The prosthesis has a hollow structure, so that in the center, within the vision zone, there is only the optical part of the lens, allowing light rays to pass through without interference.

[0012] However, the operation of implanting this capsular bag appears complex.

[0013] US patent 5,628,795 describes an ophthalmic implant made of a biocompatible material that can be implanted by a surgeon in the ciliary sulcus or in the residual natural capsular bag of a patient's eye after cataract surgery in order to serve as a receptacle for an intraocular lens.

[0014] This device is fixed by means of straight or curved hook-shaped fasteners that pass through the implant. Attaching this implant proves to be complex and time-consuming for a surgeon.

[0015] Document CN114504428A relates to an artificial capsular bag and an implantation instrument and method thereof. The artificial capsular bag comprises a capsular bag body and at least three fixation lines. The capsular bag body is provided with a capsular bag cavity and at least three fixation holes distributed in the circumferential direction. By means of this artificial capsular bag, the capsular bag environment is reconstructed for patients with severe capsular bag damage and for patients whose lens capsular bags are displaced.

[0016] This implant also proves to be complex in its use and requires too much intervention time for a surgeon. Summary of the invention

[0017] The invention aims in particular to provide an intraocular implant whose use is facilitated and which makes it possible to reduce the intervention time of a surgeon.

[0018] To this end, the invention relates to an intraocular implant comprising:

[0019] - a central body of generally hollow toroidal shape and open towards the center of the central body, the central body being configured to accommodate a secondary intraocular implant, in particular an intraocular lens

[0020] - at least two fasteners connected to the central body and equally distributed around the central body to allow attachment of the implant in the eye of a patient, each attachment comprising a proximal part relative to the central body and a distal part relative to the central body, the proximal part being formed by an elastic loop attached to the central body and the distal part by an elastic anchoring organ comprising an elongated base attached to the elastic loop and an apex generally oriented perpendicularly to the base.

[0021] Thanks to the intraocular implant according to the invention, it is possible to quickly compensate for a loss or dislocation of the capsular bag and thus avoid the need for rescheduling surgery in the event of accidental rupture of the capsular bag. In particular, the same incisions made by the surgeon for the implantation of an intraocular lens before its dislocation can be used for the injection of the capsular implant. Thus, the surgeon's intervention time is minimized, and the patient does not need to return for a second eye operation.

[0022] The intraocular implant may have one or more of the following characteristics taken alone or in combination.

[0023] The central body, generally toroidal in shape, has, for example, according to a cross-section, a general "V" shape with a flattened base and whose branches are open towards the center of the central body.

[0024] The anterior branch intended to be closest to the cornea in the implanted state may have a washer shape.

[0025] The posterior branch intended to be furthest from the cornea in the implanted state may have a perforated cup shape.

[0026] The central body, generally toroidal in shape, has in particular, according to a cross-section, a general "U" shape with a flattened base and whose opening of the branches is directed towards the center of the central body.

[0027] The width of the elastic loop is, for example, greater than the width of the apex of the elastic anchoring organ.

[0028] The elastic loop includes in particular two attachment arms to the central body and an elastic beam connecting the two attachment arms so as to define with the central body an opening of generally kidney shape.

[0029] The base of the elastic anchoring organ can be attached in a central manner with respect to the elastic loop.

[0030] The apex of the elastic anchoring element is notably made in the form of a oblong loop oriented perpendicular to the base of the "T".

[0031] The apex of the elastic anchoring member can be made in the form of a cross member.

[0032] The crossbar includes, for example, grooves or through or blind holes.

[0033] The intraocular implant can be made from a single piece.

[0034] The intraocular implant is notably produced by injection molding in one biocompatible material chosen in particular from the group of materials following: silicones, polymethyl methacrylate (PMMA), acrylates, acrylics.

[0035] The implant may comprise two attachments or two pairs of attachments, two attachments being respectively diametrically opposed.

[0036] The central body may have at least one, or even several, radial notches.

[0037] The central body is for example at least partially colored, in particular on the surface or in the mass.

[0038] The implant may further include an electronic component, in particular a sensor and / or a communication antenna, integrated by overmolding into the central body.

[0039] The invention also relates to a treatment kit to compensate for a dislocation or absence of the lens of the eye, according to which it comprises an intraocular implant injector and an intraocular implant as defined above and disposed in an intraocular implant receiving chamber.

[0040] The invention may also relate to a method of implanting an intraocular implant as defined above, in which

[0041] - incisions are made in the membranes of the eye at the level of the zonule of Zinn,

[0042] - injects the intraocular implant with an intraocular implant injector through from one of the incisions,

[0043] - the apex of each elastic anchoring organ is brought out by an incision associate.

[0044] According to one aspect, an intraocular lens can be placed in the central body of the intraocular implant. Brief description of the figures

[0060] The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments can also be combined or interchanged to provide other embodiments, without departing from the scope of the invention as defined by the claims.

[0061] Figures 2 to 4 schematically represent, respectively from a top view, in perspective and in cross-section, an intraocular implant 10 according to an embodiment of the present invention.

[0062] The intraocular implant comprises a central body 12 and at least two attachments 14 (two attachments 14 in Figures 2 to 4) connected to the central body 12. In [Fig.2], one attachment 14 is surrounded by a dotted line.

[0063] The central body 12 has a generally hollow toroidal shape and is open in direction of center C of central body 12.

[0064] As can be seen more clearly in [Fig.3] and especially in cross-section in [Fig.4], the central body 12, which is generally toric in shape, has, in cross-section, a general "V" shape with a flattened base 12-1 and whose opening of branches 12-2 and 12-3 is directed towards the center C of the central body 12. In [Fig.4], with respect to the drawing sheet, the "V" is rotated 90° with respect to a vertical line going from the top to the bottom of the sheet.

[0065] As seen in [Fig. 4], the 12-2 branch is the anterior branch, which is intended to be closest to the cornea 3 in the implanted state. This part of the central body 12 has a disc shape, referenced 12-4, with an opening 12-5, as seen in Figures 2, 3, and 4. For example, the opening 12-5 has a diameter between 5 mm and 10 mm, specifically 7 mm. The opening 12-5 can also serve as a visual reference for positioning, particularly for the orientation of the toric axis of the implant 10.

[0066] The posterior branch 12-3, that is, the one intended to be furthest from the cornea 3 in the implanted state, has a cup-shaped opening 12-6 with an aperture 12-7. For example, the aperture 12-7 has a diameter between 2 mm and 8 mm, specifically 4 mm. It is therefore understood that the diameter of the aperture 12-7 is between 40% and 80% of the diameter of the aperture 12-5.

[0067] Thus the central body 12 defines an open receptacle where a secondary intraocular implant, in particular an intraocular lens, can be housed and maintained between the branches 12-2 and 12-3 of the central body 12, the openings 12-5 and 12-7 allowing light rays to pass through and in the implanted state of the intraocular implant 12 with a secondary intraocular implant such as an intraocular lens, the light rays entering the eye and reaching the retina are almost unaffected by the intraocular implant 12, but only by the intraocular lens which will be disposed in the intraocular implant 12.

[0068] The central body 12 therefore allows, in the implanted state, to fulfill the functions of a capsular bag 5 and is configured to accommodate a secondary intraocular implant, in particular an intraocular lens.

[0069] Fig. 5 is a cross-sectional view of another embodiment which differs from that of figures 2 to 4 in that the central body 12 has, according to a cross-section, a general "U" shape with a flattened base 12-1 and whose opening of branches 12-2 and 12-3 is directed towards the center C of the central body 12.

[0070] According to the embodiment of [Fig.5], not only the front part 12-4 has a washer shape but also the rear part 12-8.

[0071] Finally, the difference in diameter between the openings 12-5 and 12-7 is greater, the the diameter of the 12-5 opening being between 2-9mm is greater than that of the 12-7 opening being between 2-9mm.

[0072] We return to the embodiment of figures 2 to 4 to detail an example of an embodiment of the fasteners 14.

[0073] As can be seen in the aforementioned figures, the two attachments 14 are connected to the central body 12 and equally distributed around it to allow the attachment of the intraocular implant 10 in the eye of a patient as will be explained in more detail later.

[0074] Each attachment 14 comprises a proximal portion 14-1 relative to the central body 12 and a distal portion 14-2 relative to the central body 12. The proximal portion 14-1 is formed by an elastic loop attached to the central body 12, which also serves as an anti-torsion means. The distal portion 14-2 is formed by an elastic anchoring element (also referred to as 14-2) comprising an elongated base 14-3 attached to the elastic loop 14-1 and an apex 14-4 oriented generally perpendicular to the base 14-3. As can be seen in the figure, the elastic anchoring element 14-2 has a general "T" shape.

[0075] The apex 14-4 of the elastic anchoring member 14-2 is formed in the form of an oblong loop oriented perpendicular to the base 14-3 of the "T". According to another embodiment, the apex 14-4 may have an "X" shape, for example, whose center is attached to the base 14-3.

[0076] The attachment 14 can be made at an angle α relative to the washer 12-4 between -25° and 25°, in particular 20° (see [Fig. 4]). This can be advantageous for better conforming to the curvature of the eye when the intraocular lens 10 is implanted. Furthermore, the angle α can be chosen to better position the lens 10, and more specifically the central body 12, relative to the iris. The central body 12 can thus be moved closer to or further from the iris.

[0077] As can be clearly seen in the top view [Fig.2], the width L1 of the elastic loop 14-1 is greater than the width L2 of the apex 14-4 of the generally T-shaped elastic anchoring member 14-2. For example, the width L1 is 5.3 mm and the width L2 is 2 mm.

[0078] The elastic loop 14-1 comprises two attachment arms 14-la to the central body 12 and an elastic beam 14-lb connecting the two attachment arms 14-la so as to define with the central body 12 an opening 14-le of generally kidney shape (see [Fig. 3]). The elastic beam 14-lb may have a smaller cross-section than the attachment arms 14-la in order to concentrate deformations at the attachment point 14 without modifying the central body 12. The elastic loop 14-1 also serves to create points of contact, in particular four points of contact, with the sulcus and / or the ciliary body in order to stabilize the intraocular lens 10 once implanted.

[0079] The base 14-3 of the elastic anchoring element 14-2, generally T-shaped, is elongated and centrally attached to the elastic loop 14-1. This base 14-3 may be conical to prevent its possible withdrawal from the sclera. To achieve this, the cross-sectional area of ​​the end of the base 14-3 that is closer to the apex 14-4 is larger than the cross-sectional area of ​​the end of the base 14-3 that is closer to the loop 14-1.

[0080] In figures 2 to 4, the intraocular implant 10 has two attachments 14 which are diametrically opposed.

[0081] Figure 6 shows another embodiment with two pairs of fasteners 14 which are therefore also distributed over the circumference of the central body 12 so that two attachments 14 are respectively diametrically opposed.

[0082] Figure 7 shows yet another embodiment which differs in particular from The embodiment of Figures 2 to 4 is characterized by the fact that, generally, the central body 12, and more specifically the washer 14-4 and / or the cup 12-6, have at least one, or even several, radial notches 12-10. These notches 12-10 allow for better absorption of mechanical stresses when the intraocular implant is inserted using an intraocular injector, as will be described later. For example, the washer 14-4 has two diametrically opposed notches 12-10. More specifically, they can be positioned so that they are aligned with the elongated notches 14-3. Also, for example, the cup 14-6 has four diametrically opposed notches 12-10, arranged in pairs and regularly spaced. For the 12-6 cup, the two radial notches 12-10 are positioned, for example, so that they are aligned with the elongated bases 14-3.

[0083] Figure 8 shows an alternative to the previous figures which differs by a cross-shaped apex 14-4 of the elastic anchoring organ 14-2.

[0084] In this case, the cross-shaped apex 14-4 may have through or blind grooves or holes, five in number as shown in [Fig.8] and referenced 14-5. This embodiment, in which the apex 14-4 is implanted in the intrascleral flap, promotes natural uveal circulation and reduces the risk of glaucoma.

[0085] The intraocular implant 10 is made, for example, from a single piece and from a single material.

[0086] More specifically, the intraocular implant 10 is made by injection molding in a biocompatible material chosen in particular from the group of the following materials: silicones, polymethyl methacrylate (PMMA), acrylates, acrylics.

[0087] In particular, for silicones, RTV type silicones can be considered. For acrylates, these can be hydrophobic or hydrophilic, or they can be a co- hybrid polymer with a hydrophilic core and a hydrophobic surface.

[0088] In the case where implantation via an intraocular injector is envisaged as will be described later, soft hydrophilic (HEMA,...) or hydrophobic (Silicones, Acryls,...) materials are chosen.

[0089] Figure 9 shows a particular embodiment intended for use in the treatment of aniridia (a pigmentation defect of the iris). As can be seen in this figure, the central body 12, and in particular the posterior portion 12-6, is at least partially colored, either on the surface or throughout. Of course, it is also possible to color the anterior portion 12-4, partially or completely. In the latter case, this anterior portion, with the opening 12-5, can act as a diaphragm.

[0090] Fig. 10 shows yet another particular embodiment in which the intraocular implant 10 further comprises an electronic component, in particular a sensor 16 and / or a communication antenna 18, integrated by overmolding into the central body 12, in particular in the anterior part 12-4. The electronic component may also comprise a microscreen for projecting information in the form of images or writing directly into the user's eye.

[0091] It is advantageous that the intraocular implant 10 can be implanted by known and widely used and approved techniques using an intraocular implant injector.

[0092] Such intraocular implant injectors are known for example from documents WO1997015253A1 and WO2006077349A1.

[0093] Figure 11 shows an example of an embodiment of a treatment kit 30 for addressing a dislocation or absence of the lens of the eye, comprising an intraocular implant injector 32 and an intraocular implant 10 according to one of the embodiments described above. The intraocular implant injector 32, whose operation is very similar to that of a syringe as described in the cited documents, has a receiving chamber 34 in which the intraocular implant 10 is placed for injection into the eye through an incision of approximately 2.2 to 2.4 mm made in the eye by the surgeon.

[0094] The injector 32 shown in [Fig. 11] has a pivoting cover 36 allowing close the receiving chamber 34 after loading the intraocular implant 10 and an injection liquid used during implantation by injection.

[0095] An example of a method of implanting the intraocular implant 10 described above consists of a surgeon making incisions in the membranes of the eye at the level of the zonule of Zinn.

[0096] Then, as shown in [Fig. 12], the intraocular implant 10 is injected with an intraocular implant injector 32 through one of the small incisions size, typically about 2.2mm in length. In [Fig. 12], we see that the implant, which is very flexible, conforms to the tubular walls of the tip of injector 32.

[0097] Once injected into the eye, the intraocular implant 10 regains its shape as shown in figures 1 to 10.

[0098] To then fix the intraocular implant 10, the surgeon exposes the apex 14-4 of each elastic anchoring organ 14-2 through an associated incision. The intraocular implant 10 in the implanted state is shown in Figures 12 and 13.

[0099] The vertices 14-4 in the form of a loop as shown in figures 2 to 7 and 9 and 10 facilitate the work of the surgeon because they can easily be hooked for example by operating instruments having a micro-hook at their ends, and then pulled through the incision.

[0100] For the embodiment of [Fig.8], the surgeon can use an operating instrument with micro-forceps at one end.

[0101] Once the intraocular implant 10, which is to replace the failing capsular bag, is in place, the surgeon can then place an intraocular lens in the central body of the intraocular implant 10, which will be held between the anterior 12-4 and posterior 12-6 parts of the central body 12. Finally, the surgeon can close the incisions, in particular with the aid of a suture fluid.

[0102] It is therefore understood that the intraocular implant 10 makes it easy to compensate for a failing capsular bag. Furthermore, this intraocular implant 10 can be used to treat aniridia and incorporate electronic components to increase the range of possible functions of this intraocular implant 10. In this latter case, but also generally as an alternative to implantation surgery, insertion of the intraocular implant 10 can also be considered via a larger incision, and implantation via an injector 32 as described above should not be required if the size of the electronic component is too large and / or its flexibility is too low.
