Description
IMPLANT INTRA-OCULAIRE A CAVITE INTERNE
La présente invention concerne le domaine technique général des systèmes intra-oculaires de correction optique de la vision, destinés à redonner à l'oeil tout ou partie de son potentiel optique.INTRAOCULAR IMPLANT WITH INTERNAL CAVITY
The present invention relates to the general technical field of intraocular optical vision correction systems, intended to restore to the eye all or part of its optical potential.
De tels systèmes constituent des implants intra-oculaires, assimilables à des prothèses, utilisés, soit lors de cataracte en remplacement du cristallin opacifié, soit, plus généralement encore, dans le but de corriger de manière interne la vision de patients atteints de défaillances visuelles définitives. Such systems constitute intraocular implants, similar to prostheses, used either during cataracts to replace the clouded lens or, more generally still, with the aim of internally correcting the vision of patients suffering from permanent visual impairment .
Les implants intra-oculaires sont généralement constitués d'une lentille optique, de forme sensiblement circulaire, munie de moyens d'immobilisation, tels que des anses élastiques, aptes à maintenir l'implant dans l'oeil. La tolérance de l'implant par l'organisme du patient est assurée en réalisant Les implants dans des matériaux bio-compatibles tels que le polyméthyl-métacrylate par exemple
En plus des contraintes classiques de précision et de tolérance de fabrication propres à la réalisation de matériels et surfaces optiques, Les implants intra-oculaires doivent répondrent à des contraintes impératives d'encombrement. Certains implants intra-oculaires sont, en effet, destinés à être implantés au sein d'une cavité de volume restreint, à savoir dans la cavité antérieure du globe oculaire.Ces implants doivent, par ailleurs, être disposés et maintenus en place dans des zones spécifiques entre L'iris et la cornée et, par exemple, en appui dans la bande ciliaire, tout en évitant un contact avec Les membranes ou zones vasculaires avoisinantes. De tels contacts sont en effet à proscrire par Les risques de prolifération ou perte cellulaire et d'irritation qu'ils générent. En raison du volume restreint du globe oculaire et de la multiplicité et de la proximité des membranes cellulaires, L'encombrement et, en particulier,
L'épaisseur des implants intra-oculaires revêtent une importance capitale.Intraocular implants generally consist of an optical lens, of substantially circular shape, provided with immobilization means, such as elastic handles, capable of holding the implant in the eye. Tolerance of the implant by the patient's body is ensured by making the implants in bio-compatible materials such as polymethyl methacrylate for example
In addition to the conventional constraints of precision and manufacturing tolerance specific to the realization of optical materials and surfaces, the intraocular implants must respond to imperative constraints of space. Certain intraocular implants are, in fact, intended to be implanted within a cavity of limited volume, namely in the anterior cavity of the eyeball. These implants must, moreover, be placed and held in place in areas specific between the iris and the cornea and, for example, in support in the ciliary band, while avoiding contact with the surrounding membranes or vascular zones. Such contacts are in fact to be avoided by the risks of proliferation or cell loss and irritation that they generate. Due to the small volume of the eyeball and the multiplicity and proximity of cell membranes, the size and, in particular,
The thickness of the intraocular implants is of paramount importance.
Ce phénomène est d'autant plus important, que la correction optique interne de patients atteints de fortes myopies nécessite des implants de puissance optique élevée et d'encombrement important. This phenomenon is all the more important as the internal optical correction of patients with high myopia requires implants of high optical power and significant bulk.
La technique antérieure a d'ailleurs déjà proposé de réaliser des implants intra-oculaires aptes à corriger la vision de patients atteints de fortes myopies. La demande de brevet
FR-A-2 631 228 décrit un implant intra-oculaire équipé d'une partie optique divergente, telle qu'une lentille biconcave à bords épais par exemple reliée par une zone de raccordement présentant un bossage reliant la partie optique aux anses d'appui.The prior art has moreover already proposed making intraocular implants capable of correcting the vision of patients suffering from myopia. The patent application
FR-A-2 631 228 describes an intraocular implant equipped with a divergent optical part, such as a biconcave lens with thick edges, for example connected by a connection zone having a boss connecting the optical part to the support handles .
Cette réalisation, si elle permet effectivement de disposer au moins certains implants myopiques dans le globe oculaire, conduit à réaliser des implants dont le volume d'encombrement total, et en particulier L'épaisseur, n'est pas assez réduit pour exclure tout risque de contact entre l'implant et Les membranes vascularisées voisines. Ce phénomène est d'autant plus marquant que la correction optique recherchée est forte, ce qui limite le domaine d'application d'un tel implant à certaines catégories de myopies. This achievement, if it actually makes it possible to have at least certain myopic implants in the eyeball, leads to producing implants whose total overall volume, and in particular the thickness, is not reduced enough to exclude any risk of contact between the implant and neighboring vascular membranes. This phenomenon is all the more striking as the optical correction sought is strong, which limits the field of application of such an implant to certain categories of myopia.
L'objet de L'invention vise, en conséquence, à proposer un implant intra-oculaire ne présentant pas Les désavantages des implants de l'art antérieur et dont L'encombrement total, et en particulier L'épaisseur, est aussi réduit que possible, pour une puissance optique donnée. The object of the invention is therefore to propose an intraocular implant which does not have the disadvantages of implants of the prior art and whose total size, and in particular the thickness, is as small as possible , for a given optical power.
Un autre objet de L'invention est de proposer un implant intra-oculaire dont Les caractéristiques d'encombrement et notamment d'épaisseur ne sont pas directement Liées au type de correction optique souhaité. Another object of the invention is to provide an intraocular implant whose dimensions and in particular thickness characteristics are not directly related to the type of optical correction desired.
Un autre objet de L'invention est de réaliser un implant intra-oculaire possédant une surface optique non polissable qui puisse être implantée dans le globe oculaire sans conduire à la création de foyers d'irritation. Another object of the invention is to produce an intraocular implant having a non-polishable optical surface which can be implanted in the eyeball without leading to the creation of foci of irritation.
Un objet supplémentaire de L'invention est de proposer un procédé de fabrication d'un tel implant. An additional object of the invention is to propose a method of manufacturing such an implant.
Les objectifs assignés à L'invention sont atteints grâce à un implant intra-oculaire comprenant un bloc optique lenticulaire et des moyens d'immobilisation de l'implant dans l'oeil d'un patient, caractérisé en ce que le bloc optique comprend, dans son épaisseur, au moins une inclusion définissant une cavité interne non débouchante contenant du vide ou un fluide, de manière à constituer une chambre de réfraction intervenant dans la définition du potentiel optique du bloc optique. The objectives assigned to the invention are achieved by means of an intraocular implant comprising a lenticular optical unit and means for immobilizing the implant in the eye of a patient, characterized in that the optical unit comprises, in its thickness, at least one inclusion defining an internal non-opening cavity containing vacuum or a fluid, so as to constitute a refraction chamber involved in the definition of the optical potential of the optical unit.
Diverses autres caractéristiques ressortent de la description faite ci-dessous en référence aux dessins annexés qui montrent, à titre d'exemples non limitatifs, des formes de réalisation de L'objet de L'invention. Various other characteristics will emerge from the description given below with reference to the appended drawings which show, by way of nonlimiting examples, embodiments of the object of the invention.
La fig. 1 illustre, selon une coupe transversale, un implant intra-oculaire selon L'invention en position à l'intérieur du globe oculaire. Fig. 1 illustrates, in a cross section, an intraocular implant according to the invention in position inside the eyeball.
La fig. 2 illustre, selon une coupe transversale, une variante de réalisation de l'implant intra-oculaire selon
L'invention.Fig. 2 illustrates, in a cross section, an alternative embodiment of the intraocular implant according to
The invention.
Les fig. 3 et 4 illustrent, selon des coupes
transversales, une troisième forme de réalisation de l'implant selon L'invention, ainsi que son assemblage.Figs. 3 and 4 illustrate, according to sections
transverse, a third embodiment of the implant according to the invention, as well as its assembly.
La fig. 5 représente, selon une vue de face, un implant selon L'invention. Fig. 5 shows, in a front view, an implant according to the invention.
Sur la fig. 1, on a représenté, selon une coupe transversale, une vue partielle de la partie antérieure du globe oculaire d'un être humain. De manière classique, le globe oculaire est limité extérieurement par une membrane transparente 2, dénommée la cornée, et intérieurement par la sclérotique non représentée sur Les figures. En arrière de la cornée 2 se trouve un diaphragme 3, dénommé iris, percé d'un orifice 4 formant la pupille dont le diamètre est variable selon l'intensité des rayons lumineux L. Le diaphragme 3 sert de cloison séparatrice du globe oculaire en définissant, avec la cornée 2, la chambre antérieure 6 laquelle est remplie d'une humeur aqueuse. In fig. 1, there is shown, in a cross section, a partial view of the anterior part of the eyeball of a human being. Conventionally, the eyeball is externally limited by a transparent membrane 2, called the cornea, and internally by the sclera not shown in the figures. Behind the cornea 2 is a diaphragm 3, called iris, pierced with an orifice 4 forming the pupil whose diameter is variable according to the intensity of the light rays L. The diaphragm 3 serves as a partition separating the eyeball by defining , with the cornea 2, the anterior chamber 6 which is filled with an aqueous humor.
Dans l'exemple de réalisation montré à la fig. 1, l'implant intra-oculaire est mis en place dans la chambre antérieure 6 et est constitué d'un bloc optique 10 d'axe principal x-x' et de moyens d'immobilisation il destinés à venir en appui contre la bande ciliaire 12 de la chambre antérieure 6 pour assurer le maintien en position de l'implant. De manière connue en soi, Les moyens d'immobilisation il peuvent consister en des anses élastiques de formes diverses, circuLaires, étoilées ou même spiralées par exemple. In the exemplary embodiment shown in FIG. 1, the intraocular implant is placed in the anterior chamber 6 and consists of an optical unit 10 with a main axis xx ′ and immobilization means 11 intended to come into abutment against the ciliary strip 12 of the anterior chamber 6 to maintain the position of the implant. In a manner known per se, the immobilization means may consist of elastic handles of various shapes, circular, star-shaped or even spiraled, for example.
Le bloc optique 10, chargé d'assurer la correction optique de la vision du patient et de redonner à l'oeil tout ou partie de son potentiel optique, comprend selon la variante de la fig. 1, deux lentilles 13, 14 de matériaux identiques ou non, rapportées et scellées L'une sur L'autre au moyen d'une interface de liaison commune 15. The optical unit 10, responsible for ensuring the optical correction of the patient's vision and for restoring to the eye all or part of its optical potential, comprises, according to the variant of FIG. 1, two lenses 13, 14 of identical or different materials, attached and sealed to each other by means of a common connection interface 15.
Il doit être noté que le bloc optique peut présenter diverses configurations selon un plan perpendiculaire à son axe principal x-x' et être, par exemple, de forme circulaire (fig. 5), ovale ou même polygonale. Dans Les exemples représentés aux fig. 1 à 5, Les deux lentilles 13, 14 sont de forme identique et sensiblement circulaire, et leur interface de liaison commune 15 se présente, en conséquence, sous la forme d'un anneau qui, dans Le cas présent, est en correspondance avec la périphérie de la lentille 13. Chaque lentille 13, 14 définit une surface optique d'incidence et une surface optique de réfraction, et la conformation des lentilles 13 et 14 est choisie pour qu'une fois rapportées et scellées L'une sur L'autre la face réfractive 13a de la lentille 13 se situe à distance de la face, qui lui est opposée, à savoir, La face d'incidence 16 de la lentille 14. Les deux faces opposées 13a, 16 définissent ainsi une inclusion dans
Le bloc optique 10 formant une cavité interne 17 non débouchante limitée à sa périphérie par L'interface de liaison commune 15, matérialisée par une arête circulaire. La cavité interne 17 ainsi définie contient un fluide, de préférence de l'air, ou du vide.It should be noted that the optical unit can have various configurations along a plane perpendicular to its main axis xx 'and be, for example, circular (fig. 5), oval or even polygonal. In the examples shown in fig. 1 to 5, the two lenses 13, 14 are of identical and substantially circular shape, and their common connection interface 15 is, consequently, in the form of a ring which, in the present case, is in correspondence with the periphery of the lens 13. Each lens 13, 14 defines an optical surface of incidence and an optical surface of refraction, and the conformation of the lenses 13 and 14 is chosen so that once attached and sealed to each other the refractive face 13a of the lens 13 is located at a distance from the face, which is opposite to it, namely, the incidence face 16 of the lens 14. The two opposite faces 13a, 16 thus define an inclusion in
The optical unit 10 forming an internal cavity 17 not emerging, limited at its periphery by the common connection interface 15, materialized by a circular edge. The internal cavity 17 thus defined contains a fluid, preferably air, or vacuum.
La variante de réalisation montrée à la fig. 1 concerne un implant myopique dans lequel Les deux lentilles 13, 14 sont constituées respectivement de deux ménisques dont Les concavités sont orientées dans la même direction, ce qui confère également à la cavité interne 17 une forme générale de ménisque possédant une concavité de même orientation. Il est avantageux que Les axes principaux de chaque ménisque soient confondus lors de la mise en place et du scellage des ménisques, afin que L'axe optique principal x-x' du bloc optique ainsi réalisé soit également confondu avec Les axes principaux des deux ménisques. The variant embodiment shown in FIG. 1 relates to a myopic implant in which the two lenses 13, 14 consist respectively of two menisci, the concavities of which are oriented in the same direction, which also gives the internal cavity 17 a general form of meniscus having a concavity of the same orientation. It is advantageous that the main axes of each meniscus are merged during the positioning and sealing of the menisci, so that the main optical axis x-x 'of the optical unit thus produced is also coincident with the main axes of the two menisci.
La variante de réalisation illustrée à la fig. 2 représente un implant intra-oculaire dans lequel la lentille 13 possède une face d'incidence 21 convexe et une face diffractive 22 présentant un réseau de micromarches 23 destinées à créer un implant multifocal. Le bloc optique est complété par une seconde lentille 14, en forme de ménisque, rapportée et scellée sur La face de La Lentille 13 comprenant le réseau des micromarches 23 et de manière à recouvrir et entourer cetles-ci à distance, la concavité de la lentille 14 faisant face aux micromarches 23. Les deux lentilles 13, 14 ont également, de préférence, le même axe optique x-x' et la cavité interne non débouchante 17 présente, dans le cas présent, une face de profil conjugué aux réseaux des micromarches 23 et une face convexe. The variant embodiment illustrated in FIG. 2 shows an intraocular implant in which the lens 13 has a convex incidence face 21 and a diffractive face 22 having a network of micromarches 23 intended to create a multifocal implant. The optical unit is completed by a second lens 14, in the form of a meniscus, attached and sealed on the face of the lens 13 comprising the network of micromarches 23 and so as to cover and surround this remotely, the concavity of the lens. 14 facing the micromarches 23. The two lenses 13, 14 also preferably have the same optical axis xx ′ and the internal non-opening cavity 17 has, in this case, a profile face combined with the networks of micromarches 23 and a convex face.
Sur la fig. 4, on a représenté à titre indicatif une autre variante de réaLisation ne différant des variantes précédentes que par La forme des Lentilles 13, 14. Ces dernières sont constituées de deux ménisques dont Les concavités sont opposées L'un par rapport à L'autre, de manière à définir une cavité interne 17 de forme biconvexe. In fig. 4, another indicative embodiment is shown by way of indication, differing from the preceding variants only in the shape of the lenses 13, 14. The latter consist of two menisci, the concavities of which are opposite one with respect to the other, so as to define an internal cavity 17 of biconvex shape.
IL doit d'ailleurs être considéré que de multiples combinaisons de formes de lentilles soit envisageables suivant la correction ou L'effet optique souhaité. Il est ainsi possible d'associer une première lentille 13 biconvexe avec une seconde
Lentille 14 plane, par exemple, tout en ménageant entre elles une cavité interne 17 non débouchante en prévoyant, sur L'une des deux lentiLles 13 ou 14, une collerette annuLaire de Liaison. IL est également possible d'associer des lentilles 13, 14 de matériau identique ou non, de rayons de courbure égaux ou non et même d'associer plus de deux Lentilles rapportées et sceLLées successivement Les unes sur Les autres dans des plans successifs en vue de réaliser plusieurs cavités internes 17.It should also be considered that multiple combinations of lens shapes are possible depending on the correction or the desired optical effect. It is thus possible to associate a first biconvex lens 13 with a second
Planar lens 14, for example, while providing between them an internal cavity 17 which does not open out by providing, on one of the two lenses 13 or 14, an annular connecting flange. It is also possible to associate lenses 13, 14 of identical or different material, with equal or different radii of curvature and even to combine more than two Lenses which are successively attached and sceLLed on each other in successive planes with a view to make several internal cavities 17.
Les performances optiques de l'implant intra-oculaire ou son potentiel optique sont déterminés par la combinaison des rayons de courbure des lentilles 13, 14, ainsi que par L'indice de réfraction des matériaux constitutifs des lentilles et du fluide contenu dans la cavité interne 17. L'épaisseur de l'implant, pour une puissance optique donnée, est d'autant plus faible que la différence entre Les indices de réfraction de L'humeur aqueuse et de l'implant, et donc du bloc optique, est grande.L'incorporation d'une cavité interne 17 contenant un fluide et, en particulier, de l'air sur Le chemin des rayons lumineux L traversant Les lentilles 13, 14 contribue à augmenter la différence entre Les indices de réfraction du milieu aqueux et de l'implant et conduit à la réalisation d'implants comparativement plus plats pour une puissance optique donnée. Cet avantage est particulièrement important dans le cas des implants myopiques qui doivent impérativement être implanté dans la cavité interne 6 de dimension réduite. Il est bien évident également qu'à la place de l'air, tout fluide ou liquide possédant un indice de réfraction intéressant peut être utilise. The optical performance of the intraocular implant or its optical potential is determined by the combination of the radii of curvature of the lenses 13, 14, as well as by the refractive index of the materials constituting the lenses and of the fluid contained in the internal cavity. 17. The thickness of the implant, for a given optical power, is all the less the greater the difference between the refractive indices of the aqueous humor and of the implant, and therefore of the optical unit. The incorporation of an internal cavity 17 containing a fluid and, in particular, air on the path of light rays L passing through the lenses 13, 14 contributes to increasing the difference between the refractive indices of the aqueous medium and of the implant and leads to the production of comparatively flatter implants for a given optical power. This advantage is particularly important in the case of myopic implants which must imperatively be implanted in the internal cavity 6 of reduced size. It is also obvious that, instead of air, any fluid or liquid having an interesting refractive index can be used.
A titre d'exemple non limitatif, un implant intra-oculaire selon L'invention d'une puissance optique de - 30 dioptries et constitué par l'association de deux ménisques de concavité opposée et d'épaisseur voisine de 0,10 mm présente, au voisinage de son axe optique x-x', une épaisseur de 0,53 mm environ. Pour une même puissance optique, un implant classique de l'art antérieur mettant en oeuvre deux lentilles biconcaves présente une épaisseur de 0,98 mm environ. By way of nonlimiting example, an intraocular implant according to the invention with an optical power of - 30 diopters and constituted by the association of two menisci of opposite concavity and of thickness close to 0.10 mm present, in the vicinity of its optical axis x-x ', a thickness of approximately 0.53 mm. For the same optical power, a conventional implant of the prior art using two biconcave lenses has a thickness of about 0.98 mm.
Le bloc optique 10 incluant la cavité interne 17 peut être obtenu seLon divers procédés. Il est ainsi possible, comme illustré aux fig. 3 et 4, de rapporter Les deux lentilles 13, 14 L'une sur L'autre, de préférence centrées sur leur axe optique principal commun, puis d'assurer leur scellage hermétique par collage à L'aide d'une colle biocompatible appliquée, au préalable, sur la zone périphérique de La lentille 13 par exemple, destinée à définir L'interface commune de liaison 15. A la place du collage, il est envisageable de procéder au soudage des deux lentilles 13, 14 par leur interface de liaison 15. On peut réaLiser cette opération en ayant recours à la technique du soudage par friction, en soumettant L'une au moins des deux lentilles à une rotation à vitesse élevée autour de son axe optique, puis en rapportant brusquement Les deux lentilles L'une sur L'autre. The optical unit 10 including the internal cavity 17 can be obtained according to various methods. It is thus possible, as illustrated in figs. 3 and 4, to attach the two lenses 13, 14 to each other, preferably centered on their common main optical axis, then to ensure their hermetic sealing by bonding using an applied biocompatible adhesive, beforehand, on the peripheral zone of the lens 13 for example, intended to define the common connection interface 15. Instead of bonding, it is possible to carry out the welding of the two lenses 13, 14 by their connection interface 15 This operation can be carried out by using the friction welding technique, by subjecting at least one of the two lenses to rotate at high speed about its optical axis, then abruptly bringing the two lenses together. The other.
L'élévation de température résultant de la friction des deux lentilles 13, 14 le long de leur interface de liaison 15 provoque une fusion superficielle des matériaux assurant un scellage hermétique des lentilles 13, 14. D'autres procédés de soudage sont bien évidemment utilisables et il doit être noté que l'implant à cavité interne peut également être obtenu par la technique du moulage.The rise in temperature resulting from the friction of the two lenses 13, 14 along their connection interface 15 causes a surface fusion of the materials ensuring a hermetic sealing of the lenses 13, 14. Other welding methods are obviously usable and it should be noted that the implant with internal cavity can also be obtained by the molding technique.
L'invention n'est pas Limitée aux exemples décrits et représentés, car diverses modifications peuvent y être apportées sans sortir de son cadre. The invention is not limited to the examples described and shown, since various modifications can be made thereto without departing from its scope.
