Description

La présente invention concerne une lentille optique de contact. Pour plus de facilité dans la description, nous choisirons l'exemple d'une lentille rigide. The present invention relates to an optical contact lens. For ease of description, we will choose the example of a rigid lens.
Un des principaux inconvénients des lentilles de contact est la captation des poussières, surtout justement en ce qui concerne les lentilles rigidesOne of the main disadvantages of contact lenses is the capture of dust, especially with regard to rigid lenses
Cette captation est facilitée par l'évasement du bord périphérique des lentilles réalisé pour faciliter la circulation du liquide lacrymal et répondre à la forme de la cornée sur laquelle repose la lentille.This capture is facilitated by the flaring of the peripheral edge of the lenses produced to facilitate the circulation of the tear fluid and respond to the shape of the cornea on which the lens rests.
Si une particule mélangée aux larmes se présente près du bord périphérique de la lentille, les mouvements de va et vient de la lentille sur la cornée font passer le bord de la lentille par-dessus cette particule.If a particle mixed with tears occurs near the peripheral edge of the lens, the back and forth movements of the lens on the cornea pass the edge of the lens over this particle.
La pression de la lentille sur la cornée peut fixer cette particule.The pressure of the lens on the cornea can fix this particle.
Cette pression ordinairement répartie sur toute la surface cornéenne couverte par la lentille se focalise alors particulièrement sur cette poussière qui constitue point d' appui. Cette pression provoque une douleur aiguë.This pressure usually distributed over the entire corneal surface covered by the lens then focuses particularly on this dust which constitutes a fulcrum. This pressure causes acute pain.
Dans les lentilles de type connu, il n'est pas évident que le flot de larmes déclenché par la douleur puisse mobiliser cette poussière et l'évacuer.In lenses of known type, it is not obvious that the stream of tears triggered by pain can mobilize this dust and evacuate it.
On a proposé des lentilles perforées pour faciliter l'oxygénation de la cornée et l'évacuation des larmes. Le brevet français n° 2.557.707 déposé par CESKOSLOVENSKA AKADEMIE décrit une lentille souple perforée dans la zone pupillaire de la lentille en son centre. Cette perforation est destinée à évacuer les larmes ; cependant, encore faut-il que le flot de larmes ait mobilisé la particule bloquée par la pression et l'ait amenée jusqu'en zone centrale pour que celle-ci puisse être évacuée. A l'évidence, le but du brevet n'est pas l'évacua¬ tion des poussières.Perforated lenses have been proposed to facilitate oxygenation of the cornea and evacuation of tears. French Patent No. 2,557,707 filed by CESKOSLOVENSKA AKADEMIE describes a flexible lens perforated in the pupillary zone of the lens in its center. This perforation is intended to evacuate tears; however, it is still necessary that the flood of tears mobilized the particle blocked by the pressure and brought it to the central area so that it can be evacuated. Obviously, the purpose of the patent is not the evacuation of dust.
En fait, il est probable que la pression qui s'exerce exclusivement sur la particule s'oppose à sa mobilisation par les larmes. Cette particule a au contraire tendance à s'incruster dans la surface cornéenne . Les lentilles connues présentent généralement deux dégagements annulaires périphériques ou une zone de dégagement de courbure asphérique destinés à faciliter le passage des larmes sous la lentille mais ces dégagements qui relèvent le bord de la lentille contribuent également au passage des particules sous la lentille.In fact, it is likely that the pressure exerted exclusively on the particle is opposed to its mobilization by tears. On the contrary, this particle tends to become embedded in the corneal surface. Known lenses generally have two peripheral annular clearances or an aspherical curvature clearing zone intended to facilitate the passage of tears under the lens, but these clearances which raise the edge of the lens also contribute to the passage of particles under the lens.
La présente invention vise à solutionner les problèmes ci-dessus : faciliter la circulation et l'évacua¬ tion des larmes, et également faciliter l'interception d'une particule qui pourrait passer sous la lentille et son évacuation par les larmes.The present invention aims to solve the above problems: facilitate the circulation and evacuation of tears, and also facilitate the interception of a particle which could pass under the lens and its evacuation by tears.
A cet effet, la lentille optique de contact selon 1 ' invention présentant une face avant externe convexe et une face postérieure concave qui s'applique sur la cornée de l'oeil se caractérise essentiellement en ce que la face postérieure présente en retrait de son bord 5 et dans la portion périphérique de la face 2 qui s'applique sur la cornée une zone annulaire 3 qui est espacée ou écartée par rapport à la surface de la cornée et au moins un perçage 4 débouchant de la face avant dans ladite zone 3.To this end, the optical contact lens according to the invention having a convex external front face and a concave rear face which is applied to the cornea of the eye is essentially characterized in that the rear face has recessed from its edge. 5 and in the peripheral portion of the face 2 which is applied to the cornea an annular zone 3 which is spaced or spaced from the surface of the cornea and at least one bore 4 emerging from the front face in said zone 3.
Suivant une autre caractéristique, la lentille optique de contact selon l'invention, présentant une face antérieure convexe et une face postérieure concave qui s'applique sur la cornée se caractérise essentiellement en ce que sa face postérieure présente au voisinage de sa périphérie, à l'extérieur de la zone optique, une gorge annulaire dans laquelle est réalisée au moins une perforation traversant la lentille de l'une à l'autre face.According to another characteristic, the optical contact lens according to the invention, having a convex anterior face and a concave posterior face which is applied to the cornea, is essentially characterized in that its posterior face presents in the vicinity of its periphery, at l outside the optical zone, an annular groove in which at least one perforation is made passing through the lens from one to the other face.
Suivant une autre caractéristique de l'invention, la gorge de la face arrière est réalisée sur tout le pourtour de la lentille en retrait de son bord.According to another characteristic of the invention, the groove of the rear face is produced around the entire periphery of the lens set back from its edge.
Suivant une autre caractéristique de l'invention, la ou les perforations débouchent depuis la face avant dans la gorge de la face arrière et inversement.According to another characteristic of the invention, the perforation or perforations open from the front face into the groove of the rear face and vice versa.
Suivant encore une autre caractéristique de l'invention, plusieurs perforations angulairement espacées sont ménagées débouchant dans la gorge.According to yet another characteristic of the invention, several angularly spaced perforations are formed opening into the groove.
D ' autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description ci- après de formes de réalisation de l'invention données à titre d'exemples non limitatifs et illustrées par les dessins joints dans lesquels :Other advantages and characteristics of the invention will appear on reading the following description of embodiments of the invention given by way of non-limiting examples and illustrated by the accompanying drawings in which:
- la figure 1 est une vue en coupe d'une lentille selon une forme de réalisation,FIG. 1 is a sectional view of a lens according to one embodiment,
- la figure 2 est une vue de face de la lentille selon la figure 1,FIG. 2 is a front view of the lens according to FIG. 1,
- les figures 3 et 4 sont des vues en coupe et de face d ' une lentille selon une autre forme de réalisation de 1 ' invention.- Figures 3 and 4 are sectional and front views of a lens according to another embodiment of the invention.
Telle que représentée dans les exemples de réalisation des figures 1, 2, 3 et 4, la lentille optique selon 1 ' invention présente une face avant externe 1 convexe et une face postérieure 2 concave.As shown in the exemplary embodiments of Figures 1, 2, 3 and 4, the optical lens 1 according to the invention has an outer front face 1 convex and a rear face 2 concave.
Sur la face postérieure, en retrait du bord 5 de la lentille et de la portion périphérique de la face 2 de la lentille qui s'applique sur la cornée de l'oeil, et en dehors de la zone optique centrale, une zone 3 annulaire de la lentille est écartée ou espacée de la surface de la cornée. La face arrière 2 est celle qui s'applique contre la cornée. La face arrière 2 présente au voisinage de sa périphérie et à l'extérieur de la zone optique centrale une gorge annulaire 3 dans laquelle est réalisée au moins une perforation 4 débouchante.On the posterior surface, set back from the edge 5 of the lens and from the peripheral portion of the face 2 of the lens which is applied to the cornea of the eye, and outside the central optical zone, an annular zone 3 of the lens is spread or spaced from the surface of the cornea. The rear face 2 is that which is applied against the cornea. The rear face 2 has, in the vicinity of its periphery and outside the central optical zone, an annular groove 3 in which at least one through-hole 4 is made.
La gorge 3 est réalisée sur tout le pourtour de la lentille en retrait de son bord 5.The groove 3 is produced around the entire periphery of the lens set back from its edge 5.
La gorge de profondeur adaptée peut être de section en arc de courbe ou avec un fond plat et de rebords en dépouille plus ou moins évasés ou droits.The adapted depth groove can be of cross-sectional arc or with a flat bottom and more or less flared or straight undercut edges.
Dans l'exemple de réalisation de l' invention représentée aux figures 1-2, le bord 5 de la lentille présente au niveau de la face postérieure 2 un premier dégagement périphérique 6 qui relève ledit bord pour permettre le passage du liquide lacrymal.In the embodiment of the invention shown in Figures 1-2, the edge 5 of the lens has at the rear face 2 a first peripheral clearance 6 which raises said edge to allow the passage of the tear fluid.
La gorge 3 est réalisée au-delà du dit dégagement périphérique. Un deuxième dégagement périphérique 7 peut être réalisé après la gorge 3 qui est ainsi comprise entre le premier et le deuxième dégagement ou inclue dans la zone de dégagement asphérique.The groove 3 is produced beyond said peripheral clearance. A second peripheral relief 7 can be produced after the groove 3 which is thus between the first and the second relief or included in the aspherical relief zone.
Ou encore à la limite de cette zone de dégagement, soit vers le bord, soit juste avant la zone optique, le dessus des dégagements en coupe n'est qu'un schéma et ne tient pas compte des courbures réelles qui pourraient être réalisées. Avantageusement, la lentille selon l'invention est pourvue d'une pluralité de perçages débouchant dans la gorge 3 de la face arrière 2 depuis la face avant 1.Or again at the limit of this clearance zone, either towards the edge, or just before the optical zone, the top of the sectional clearances is only a diagram and does not take account of the real curvatures which could be produced. Advantageously, the lens according to the invention is provided with a plurality of holes opening into the groove 3 of the rear face 2 from the front face 1.
Ces perçages sont décalés angulairement de manière régulière ou non.These holes are offset angularly regularly or not.
Chacune des perforations 4 est orientée perpendiculairement à la paroi externe 1 de la lentille, mais les bords peuvent être droits, biseautés ou en diabolo plus ou moins évasés vers l'avant ou l'arrière.Each of the perforations 4 is oriented perpendicular to the outer wall 1 of the lens, but the edges can be straight, bevelled or diabolically more or less flared towards the front or the rear.
Dans l'exemple des figures 1-2 sont représentés schématiquement quatre perçages 4 décalés angulairement à 90°.In the example of Figures 1-2 are shown schematically four holes 4 angularly offset by 90 °.
Il se peut, cependant, qu'il n'y en ait que trois décalés à 120° ou qu'il y en ait plus.It may be, however, that there are only three offset by 120 ° or that there are more.
La profondeur de la gorge et la dimension des perçages peuvent varier en fonction du diamètre et/ou de l'épaisseur de la lentille.The depth of the groove and the size of the holes can vary depending on the diameter and / or thickness of the lens.
Lorsqu'une particule est entrainée entre l'oeil et la lentille, son trajet l'amène au niveau de la gorge 3. Du fait de l'écartement entre le fond de la gorge et la lentille, la pression exercée sur la cornée par 1 ' intermédiaire de la particule va être réduite ou supprimée lorsque la particule est dans la gorge, ce qui atténue la douleur.When a particle is entrained between the eye and the lens, its path brings it to the level of the throat 3. Due to the distance between the back of the throat and the lens, the pressure exerted on the cornea by The intermediate of the particle will be reduced or removed when the particle is in the throat, which alleviates the pain.
Le clignement des paupières provoque un mouvement rotatif de la lentille, lequel amène un des orifices 4 en face de la particule qui peut alors être évacuée à l'extérieur par les larmes.The blinking of the eyelids causes a rotary movement of the lens, which brings one of the orifices 4 in front of the particle which can then be evacuated outside by tears.
Aux figures 3 et 4 est représentée une autre forme de réalisation de lentille optique de contact selon une autre forme de réalisation de l'invention.In Figures 3 and 4 is shown another embodiment of the optical contact lens according to another embodiment of the invention.
Cette lentille présente une face avant 1, une face arrière 2, une gorge annulaire 3 près de son bord 5 et un ou des perçages 4.This lens has a front face 1, a rear face 2, an annular groove 3 near its edge 5 and one or more bores 4.
Elle se distingue de la lentille représentée aux figures 1 et 2 en ce que les dégagements périphériques 6 et 7 ne sont pas réalisés ou sont beaucoup moins marqués. Son bord 5 vient au contact le plus ajusté possible avec la cornée.It differs from the lens shown in Figures 1 and 2 in that the peripheral clearances 6 and 7 are not made or are much less marked. Its edge 5 comes into the most adjusted contact possible with the cornea.
Du fait de cet ajustement, le renouvellement lacrymal s'effectue alors par le moyen de la gorge creuse 3 périphérique et du ou des perçages 4. Le dispositif se trouve avoir deux fonctions : il contribue à assurer l'oxygénation de la cornée et l'évacuation des particules indésirables s'il y en a.Due to this adjustment, the lacrimal renewal is then carried out by means of the peripheral hollow throat 3 and of the borehole (s) 4. The device is found to have two functions: it contributes to ensuring the oxygenation of the cornea and the removal of unwanted particles, if any.
Le bord 5 ajusté de la lentille contribue à éviter le passage des particules entre ladite lentille et la cornée, la gorge et la ou les perforations contribuent à éviter un effet de ventouse sous la lentille.The adjusted edge 5 of the lens contributes to preventing the passage of particles between said lens and the cornea, the throat and the perforation (s) contributes to avoiding a suction cup effect under the lens.
L'invention est applicable à tout type de lentilles optiques de contact connues telles que notamment les lentilles de type rigide perméables à l'oxygène mais également aux lentilles souples connues. The invention is applicable to any type of known optical contact lenses such as in particular the rigid type lenses permeable to oxygen but also to known flexible lenses.
