Abstract

The insert includes an episclerical bridge in the form of an arch in a single piece with two feet (72,73) connected by a mid part (71). Each foot has an end surface adapted to be placed so that it rests on the sclera. The mid part is adapted to receive at least one loop of a surgical suture (8) that goes into the sclera, the suture provoking expansion of the sclera under the arch of the insert.

La presente invention concerne ltophtalmologie et plus particulierement le traitement chirurgical de la presbytie. La presbytie est une affection qui touche le sujet autour de la quarantaine et qui se traduit par une difficulte, puis une impossibilite de la lecture de pres. La technique proposee par ['invention procede de la chirurgie. Son but est de liberer la presbyte de la contrainte du port de  The present invention relates to ophthalmology and more particularly to the surgical treatment of presbyopia. Presbyopia is a condition that affects the subject around the age of 40 and which results in difficulty, then an impossibility of reading near. The technique proposed by the invention is a surgical procedure. Its purpose is to free the presbyopic from the constraint of the port of

lunettes ou de lentilles de contact.  glasses or contact lenses.

Selon les nouvelles approches de la physio-pathogenie de la presbytie, cette derriere est due a un accroissement du diametre du cristallin. Cette augmentation est due a ['age. Le cristallin, enferme dans un sac, est suspendu a o la sclere, coque exterieure de ['ceil, le long d'un anneau de celle-ci, le muscle ou corps ciliaire, par un ligament appele zonule. L'augentation du diametre du cristallin provoque une distension de la zonule. Les fibres zonulaires se detendent, rendant les contractions du muscle ciliaire moins efficaces pour firer  According to new approaches to the pathophysiology of presbyopia, the latter is due to an increase in the diameter of the lens. This increase is due to age. The lens, enclosed in a bag, is suspended from the sclera, the outer shell of the eye, along a ring thereof, the muscle or ciliary body, by a ligament called a zonule. The silvering of the diameter of the lens causes a distension of the zonule. Zonular fibers relax, making ciliary muscle contractions less effective at pulling

diametre de la sclere situe a ['aplomb du corps ciliaire.  diameter of the sclera located above the ciliary body.

Le brevet fran$ais 2 784 287 (G. BaikofI9 propose d'augmenter localement en plusieurs endroits le diametre de l'anneau scleral au niveau du corps ciliaire de maniere a retendre la zonule. Ceci est obtenu en disposant contre la sclere, o des segments arques que l'on met en place dans des passants incises dans ltepaisseur de la sclere, chaque segment prenant appui sur la sclere par ses extremites elargies tandis que la partie mediane du segment exerce sur le passant une force d' ecartement vers l' exterieur. Pour faciliter la mise en place, chaque segment est en pratique forme de deux pieces, de fa$on a eviter d'avoir a passer une extremite elargie du segment dans le passant incise dans la sclere, et reduire  French patent 2,784,287 (G. BaikofI9 proposes locally increasing in several places the diameter of the scleral ring at the level of the ciliary body so as to tighten the zonule. This is obtained by placing against the sclera, where arched segments which are placed in passers incised in the thickness of the sclere, each segment resting on the sclere by its enlarged ends while the middle part of the segment exerts a force of spreading towards the outside To facilitate the installation, each segment is in practice formed of two pieces, so as to avoid having to pass an enlarged end of the segment in the pass incised in the sclera, and reduce

la largeur de ['incision, et ameliorer la stabilite du segment une fois mis en place.  the width of the incision, and improve the stability of the segment once it is in place.

Conformement a la presente invention, un insert pour le traitement de la presbytie est constitue par un pont episcleral (pose sur la sclere et non place dans la sclere en totalite ou partiellement), en forme d'arche, en une seule piece ayant deux pieds relies par une entretoise, chaque pied ayant une surface d'extremite adaptee a etre placee en appui sur la sclere, ltentretoise etant adaptee a recevoir  In accordance with the present invention, an insert for the treatment of presbyopia is constituted by an episcleral bridge (placed on the sclera and not placed in the sclera wholly or partially), in the shape of an arch, in a single piece having two feet. connected by a spacer, each leg having an end surface adapted to be placed in abutment on the sclera, the spacer being adapted to receive
