摘要:
Intraocular lens with accommodation capacity comprising a first optical member (1) having a dynamic optical power, to which a second optical member (2) with a fixed optical power is affixed, in such a manner that at least a central part of each of one of one of the curved surfaces (2a, 2b) of the second optical member (2) and of at least one of the surfaces (1a, 1b) of the first optical member (1) are in contact with each other, the second optical member (2) and the first optical member (1) providing a joint optical power which is variable between a condition of minimum optical power corresponding to a condition of disaccommodation and a condition maximum optical power corresponding to a condition of accommodation, and the first optical member and an anchoring system (3) being designed to change the curvature of at least one of the surfaces (1a, 1b) of the first optical element (1) progressively between a maximum curvature corresponding to the condition of accommodation in response to a minimum effective traction force of the ciliary muscle received through the anchoring system (3), and a maximum effective traction force of the ciliary muscle received by the anchoring system (3).La présente invention concerne une lentille intraoculaire à capacité daccommodation comprenant un premier élément optique (1) ayant une puissance optique dynamique, auquel un second élément optique (2) avec une puissance optique fixe est fixé, de telle manière quau moins une partie centrale de chacune des surfaces incurvées (2a, 2b) du second élément optique (2) et dau moins lune des surfaces (1a, 1b) du premier élément optique (1) sont en contact les unes avec les autres, le second élément optique (2) et le premier élément optique (1) fournissant une puissance optique commune qui est variable dune condition de puissance optique minimale correspondant à une condition de désaccommodation à une condition de puissance optique maximale correspondant à une condition daccommodation, et le premier
