Abstract

Scleral distension ring is made of an horizontal ring (2) and vertical bands (3) forming a ring chamber. This chamber is linked to a vacuum pump via the metallic pipe (7). The ring can be positioned exactly by use of diametrical cross (10) and markers (9) in form of small plates placed inside the ring.

Description

L'invention se situe dans le domaine de l'ophtalmologie et concerne plus précisément un anneau de distension sclérale comportant des moyens de repérage, adapté pour le traitement de la presbytie (A.D.S.T.P.), avec éventuellement un moyen complémentaire pour renforcer l'effet dudit anneau. The invention relates to the field of ophthalmology and more specifically relates to a scleral distension ring comprising locating means, suitable for the treatment of presbyopia (ADSTP), with possibly additional means for enhancing the effect of said ring .

Les anneaux de succion sont des pièces connues et utilisées dans les techniques de chirurgie cornéenne. Ils sont formés de deux bandes verticales circulaires réunies par une couronne horizontale, les bandes délimitant ainsi une chambre annulaire dont la partie ouverte s'applique sur la sclère de l' oeil . La chambre est en communication avec une pompe à vide par l'intermédiaire d'un petit tube métallique et d'un raccord en plastique souple. Avant une intervention sur la cornée, le praticien place cet anneau de succion sur la sclère de l'oeil. Puis, quand la pompe à vide est mise en marche, une dépression s'établit dans la chambre annulaire qui aspire la sclère à son contact entraînant une élévation de la pression intra-oculaire. Le globe oculaire est donc maintenu fermement et permet au chirurgien d'intervenir plus aisément sur la cornée par exemple pour la pose d'anneaux intra-cornéens destinés au traitement de myopies faibles. Suction rings are known parts and used in corneal surgery techniques. They are formed by two vertical circular bands joined by a horizontal crown, the bands thus delimiting an annular chamber, the open part of which is applied to the sclera of the eye. The chamber is in communication with a vacuum pump via a small metal tube and a flexible plastic fitting. Before an intervention on the cornea, the practitioner places this suction ring on the sclera of the eye. Then, when the vacuum pump is started, a vacuum is established in the annular chamber which sucks the sclera on contact, causing an increase in intraocular pressure. The eyeball is therefore held firmly and allows the surgeon to intervene more easily on the cornea for example for the placement of intra-corneal rings intended for the treatment of weak myopias.

La fonction de cet anneau de succion est donc bien connue et son emploi s'est généralisé pour ce type d'intervention. The function of this suction ring is therefore well known and its use has been generalized for this type of intervention.

Mais la Demanderesse a constaté, que dans certaines conditions, notamment en positionnant de façon très précise un tel anneau de succion sur la sclère, et plus précisément en utilisant un anneau de dimension et de forme mieux adaptés à la morphologie du patient, l'anneau en question entraînait en regard de la chambre annulaire, une expansion sclérale en regard de la zone périphérique du cristallin. La Demanderesse a également constaté qu'en maintenant l'anneau de succion sur l'oeil pendant un laps de temps bien déterminé, cette distension sclérale devenait rémanente pour une longue durée. Cette distension sclérale qui augmente l'espace entre le cristallin et le corps ciliaire donne à la zonule davantage de place et de force pour tirer sur l'équateur du cristallin, ce qui va dans le sens d'une augmentation de son efficacité et de son action sur le changement de la forme du cristallin et de l'accommodation. Un des mérites de la Demanderesse a donc été d'imaginer et mettre au point un anneau de distension sclérale qui accentue ce phénomène de façon localisée et rémanente, induisant une modification de la convexité du cristallin, c'est-à-dire une suppression au moins partielle de la presbytie. D'éventuels moyens complémentaires ont été aussi imaginés pour renforcer ces effets, en accentuant encore la distension sclérale provoquée par cet anneau, en vue du traitement d'une presbytie plus sérieuse. However, the Applicant has found that, under certain conditions, in particular by positioning such a suction ring very precisely on the sclera, and more precisely by using a ring of dimension and shape better suited to the morphology of the patient, the ring in question led, opposite the annular chamber, to a scleral expansion opposite the peripheral zone of the lens. The Applicant has also found that by maintaining the suction ring on the eye for a well-defined period of time, this scleral distension becomes remanent for a long time. This scleral distension which increases the space between the lens and the ciliary body gives the zonule more room and force to pull on the equator of the lens, which goes in the direction of an increase in its efficiency and its action on the change in the shape of the lens and accommodation. One of the merits of the Applicant has therefore been to imagine and develop a scleral distension ring which accentuates this phenomenon in a localized and persistent manner, inducing a modification of the convexity of the lens, that is to say a suppression at the less partial to presbyopia. Possible additional means have also been devised to reinforce these effects, by further accentuating the scleral distension caused by this ring, with a view to the treatment of more serious presbyopia.

L'invention a donc pour objet principal un anneau de distension sclérale pour le traitement de la presbytie, formé d'une couronne horizontale encadrée de bandes verticales qui délimitent une chambre annulaire communiquant par un tube avec une pompe à vide l'anneau utilisé étant adapté à la morphologie du patient et disposant de moyens pour son repérage et son positionnement par rapport au limbe et à la cornée. The main object of the invention is therefore a scleral distension ring for the treatment of presbyopia, formed by a horizontal crown framed by vertical bands which delimit an annular chamber communicating by a tube with a vacuum pump the ring used being adapted to the morphology of the patient and having means for its location and positioning relative to the limbus and the cornea.

Des moyens éventuels complémentaires renforcent les effets dudit anneau de distension sclérale. Possible additional means reinforce the effects of said scleral distension ring.

Selon une caractéristique particulière de l'invention les moyens de repérage et de positionnement de l'anneau sont constitués de marqueurs et/ou d'un croisillon diamétral au centre de l'anneau, les marqueurs étant avantageusement des petites plaquettes diamétralement opposées prolongeant la couronne vers l'intérieur de l'anneau. According to a particular characteristic of the invention, the means for locating and positioning the ring consist of markers and / or a diametral cross at the center of the ring, the markers advantageously being small diametrically opposite small plates extending the crown. inward of the ring.

Selon une autre caractéristique particulière de l'invention, les moyens éventuels complémentaires de renforcement des effets de l'anneau de distension sclérale sont constitués d'anneaux intra-cornéens ayant une forme appropriée apte à induire des déformations mécaniques de la sclère. D'autres caractéristiques et avantages de l'invention seront mieux perçus à la lecture de la description qui va suivre d'une forme de réalisation prise à titre d'exemple non limitatif dans laquelle il est fait référence aux dessins annexés qui représentent Figure 1, une vue schématique en perspective du dessous d'un anneau de distension sclérale Figure 2, le même anneau vu de dessus L'anneau de distension 1, présenté aux figures 1 et 2, est un anneau métallique destiné à être placé sur le globe oculaire à environ 2 mm du limbe. I1 est formé d'une couronne horizontale 2 encadrée de deux bandes circulaires verticales 3. La couronne et les deux bandes délimitent une chambre annulaire 4. Les rebords externes 5 des bandes verticales 3 sont un peu décalés en hauteur pour pouvoir épouser la rotondité du globe oculaire quand l'anneau est mis en place. Dans la couronne 2 est prévu un orifice 6 communiquant avec un petit tube métallique 7 relié par un raccord souple 8 à une pompe à vide non représentée, pour établir une dépression dans la chambre 4. According to another particular characteristic of the invention, the possible additional means for reinforcing the effects of the scleral distension ring consist of intra-corneal rings having an appropriate shape capable of inducing mechanical deformations of the sclera. Other characteristics and advantages of the invention will be better perceived on reading the description which follows of an embodiment taken by way of nonlimiting example in which reference is made to the appended drawings which represent FIG. 1, a schematic perspective view from below of a scleral distension ring Figure 2, the same ring seen from above The distension ring 1, presented in Figures 1 and 2, is a metal ring intended to be placed on the eyeball to about 2 mm from the limbus. I1 is formed by a horizontal crown 2 framed by two vertical circular bands 3. The crown and the two bands define an annular chamber 4. The outer edges 5 of the vertical bands 3 are slightly offset in height in order to be able to match the roundness of the globe eye when the ring is in place. In the crown 2 is provided an orifice 6 communicating with a small metal tube 7 connected by a flexible connector 8 to a vacuum pump not shown, to establish a vacuum in the chamber 4.

Cet anneau de distension sclérale est équipé de moyens de repérage et de positionnement grâce auxquels on peut le placer de façon précise par rapport au limbe et à la cornée. Les moyens sont essentiellement des marqueurs formés de petites plaquettes 9 diamétralement opposées prolongeant la couronne 2 vers l'intérieur de l'anneau. Ces marqueurs permettent de centrer l'anneau par rapport au limbe. On voit à la figure 2 qu'un autre moyen de positionnement est constitué d'un croisillon diamétral 10, permettant de placer celui-ci au centre de l'anneau, bien symétriquement de part et d'autre de la cornée. This scleral distension ring is equipped with locating and positioning means by which it can be placed precisely with respect to the limbus and the cornea. The means are essentially markers formed from small diametrically opposite small plates 9 extending the crown 2 towards the inside of the ring. These markers are used to center the ring relative to the limbus. We see in Figure 2 that another positioning means consists of a diametral spider 10, to place it in the center of the ring, symmetrically on either side of the cornea.

Un tel anneau de distension sclérale doit être, dans sa forme, ses dimensions et sa taille, adapté à la morphologie du patient, pour le traitement de la presbytie. Ainsi le praticien disposera d'une pluralité d'anneaux convenant pour chacun, y compris des anneaux de forme ovale adaptés à certaines cornées de forme ovale à grand axe horizontal. A titre d'exemple, on indique que le diamètre interne des anneaux varie de 11,5 à 12,5 mm, le diamètre externe variant de 15,5 à 17,5 mm ce qui ménage un espace de 4 mm environ entre les deux rebords de l'anneau. Such a scleral distension ring must be, in its shape, its dimensions and its size, adapted to the morphology of the patient, for the treatment of presbyopia. Thus the practitioner will have a plurality of rings suitable for each, including oval rings adapted to certain oval corneas with large horizontal axis. By way of example, it is indicated that the internal diameter of the rings varies from 11.5 to 12.5 mm, the external diameter varying from 15.5 to 17.5 mm, which saves a space of approximately 4 mm between the two. ring edges.

L'anneau de distension sclérale est donc positionné de façon précise sur le globe oculaire, par rapport au limbe et à la cornée grâce aux moyens précités. Ensuite une dépression est établie dans la chambre 4 qui aspire la sclère à son contact. Cette dépression est maintenue pendant environ deux minutes sur l'oeil pour provoquer une distension rémanente de la sclère qui atténue la presbytie. The scleral distension ring is therefore positioned precisely on the eyeball, relative to the limbus and the cornea using the aforementioned means. Then a vacuum is established in the chamber 4 which sucks the sclera on contact. This depression is maintained for about two minutes on the eye to cause a persistent distension of the sclera which attenuates presbyopia.

Pour accentuer cette distension, dans le cas du traitement d'une presbytie plus sérieuse, des moyens complémentaires peuvent être utilisés. Ainsi l'implant d'anneaux intra-cornéens est avantageux non pas sur le plan de leurs effets optiques sur la vision, mais du fait des déformations mécaniques qu'ils induisent sur la sclère, qui vont dans le sens de la distension sclérale provoquée par l'anneau de distension. On modifie en conséquence les anneaux intra-cornéens connus pour le traitement de la myopie en leur donnant une forme appropriée.To accentuate this distension, in the case of the treatment of more serious presbyopia, complementary means can be used. Thus the implant of intra-corneal rings is advantageous not in terms of their optical effects on vision, but because of the mechanical deformations they induce on the sclera, which go in the direction of the scleral distension caused by the distension ring. The intra-corneal rings known for the treatment of myopia are modified accordingly by giving them an appropriate shape.
