An intraocular lens (IOL) (20) includes an optic (24) for focusing light and an accommodation assembly (26) for axially moving and/or deforming the optic in response to naturally occurring actions of the eye, thus allowing a patient to more effectively focus on near objects. In addition, the optic may be multifocal or aspheric, wherein the maximum add power of the lens is combined with the increase in diopter power obtained through axial movement and/or deformation of the optic, resulting in enhanced accommodation.

L'invention porte sur un implant intraoculaire (20) comprenant une optique (24) destinée à focaliser la lumière et un ensemble d'accommodation (26) destiné à déplacer et/ou déformer axialement l'optique en réponse à des actions naturelles de l'oeil, ce qui permet au patient de mieux focaliser des objets proches. De plus, l'optique peut être multifocale ou asphérique, la puissance d'addition maximum de la lentille étant associée à l'augmentation de la puissance dioptrique obtenue par le déplacement axial et/ou la déformation axiale de l'optique, entraînant ainsi une amélioration de l'accommodation.
