要約
(EN)
The purpose of the present invention is to provide an adjustable intraocular lens exhibiting satisfactory focusing power. This intraocular lens (1) has an optical part (10) comprising a lens, and lens support parts (20) provided at peripheral edge parts of the optical part (10). The lens support parts (20) have a first edge part (201) moveably linked to the peripheral edge part of the optical part (10) by a linking part (50), and an opposite edge part (202) fastened to an equatorial part (Se) of the capsule of the lens (S), the first edge part (201) and the opposite edge part (202) being located at mutually opposite sides from the center (O) of the optical part (10), and being formed so as to extend radially outward in loop shape to encircle the periphery of the optical part (10) from the first edge part (201) to the opposite edge part (202). In response to movement of the capsule of the lens (S) in proximity to the equatorial part (Se), produced by focusing of the eye, the opposite edge parts (202) of the lens support parts (20) move in a direction closer together or apart, whereby the optical part (10) moves in the direction of the optical axis.

La présente invention a pour objet une lentille intraoculaire ajustable présentant une puissance de mise au point satisfaisante. Cette lentille intraoculaire (1) présente une partie optique (10) comprenant une lentille, et des parties de support de lentille (20) mises en place au niveau des parties des bords périphériques de la partie optique (10). Les parties de support de lentille (20) présentent une première partie de bord (201) liée de façon déplaçable à la partie de bord périphérique de la partie optique (10) par une partie de liaison (50), et une partie de bord opposé (202) fixée à une partie équatoriale (Se) de la capsule de la lentille (S), la première partie de bord (201) et la partie de bord opposé (202) étant situées sur des côtés mutuellement opposés du centre (O) de la partie optique (10), et étant formées de sorte à s'étendre dans la direction radiale vers l'extérieur en forme de boucle de sorte à encercler la périphérie de la partie optique (10) depuis la première partie de bord (201) vers la partie de bord opposé (202). En réponse au mouvement de la capsule de la lentille (S) à proximité de la partie équatoriale (Se), produit par la mise au point de l'œil, les parties de bord opposé (202) des parties de support de lentille (20) se déplacent dans une direction de sorte à se rapprocher ou à s'éloigner, ce qui permet à la partie optique (10) de se déplacer dans la direction de l'axe optique.

本発明は、焦点調節力を十分に発揮することができる調節眼内レンズを提供することを目的とする。本調節眼内レンズ1は、レンズからなる光学部10と、光学部10の周縁部に設けられたレンズ支持部20とを備える。レンズ支持部20は光学部10の周縁部に連結部50を介して可動可能な状態で連結される一方端部201と、水晶体嚢S赤道部Seに係止される他方端部202とを有し、一方端部201と他方端部202が光学部10の中心Oを介して互いに反対側に位置しかつ一方端部201から他方端部202にかけて光学部10の周囲を取り囲むループ状に径方向外側で延びる態様で形成される。眼の焦点調節により発生する赤道部Se付近における水晶体嚢Sの動きに応じてレンズ支持部20の他方端部202同士が近接離間方向に移動することにより光学部10が光軸方向に移動する。
