Abstract[English]
A multi-layer intraocular lens (IOL) includes a lens body, including an anterior diffractive optics layer, comprising a first biocompatible material, and a posterior diffractive optics layer, comprising a second biocompatible material that is different from the first biocompatible material. The anterior diffractive optics layer and the posterior diffractive optics layer are sealed in a peripheral non-optic portion of the lens body with a gap between the anterior diffractive optics layer and the posterior diffractive optics layer.[French]
L'invention concerne une lentille intraoculaire (LIO) multicouche comprenant un corps de lentille, comprenant une couche d'optique diffractive antérieure, comprenant un premier matériau biocompatible, et une couche d'optique diffractive postérieure, comprenant un second matériau biocompatible qui est différent du premier matériau biocompatible. La couche d'optique diffractive antérieure et la couche d'optique diffractive postérieure sont scellées dans une partie non optique périphérique du corps de lentille avec un espace entre la couche d'optique diffractive antérieure et la couche d'optique diffractive postérieure.
