Abstract[English]
An IOL includes an optic having an anterior optic surface configured to receive light passing into an eye in which the IOL is implanted and a posterior optic surface opposite the anterior surface. The IOL includes at least one of refractive and diffractive structures configured to improve vision of the eye. A metasurface is configured to reduce reflection in the human visible spectrum from the anterior surface. The IOL further may further include a peripheral portion surrounding the optic, a metasurface may additionally or alternatively be formed on a peripheral portion and be configured to act as a filter to reduce transmission in the human visible spectrum into the peripheral portion through a peripheral anterior surface of the peripheral portion.[French]
Une lentille intraoculaire comprend une optique ayant une surface optique antérieure configurée pour recevoir la lumière qui passe à travers un œil dans lequel la lentille intraoculaire est implantée et une surface optique postérieure opposée à la surface antérieure. La lentille intraoculaire comprend au moins l'une de structures de réfraction et de diffraction configurées pour améliorer la vision de l'œil. Une métasurface est configurée pour réduire la réflexion par la surface antérieure sur le spectre visible humain. La lentille intraoculaire peut en outre comprendre une partie périphérique qui entoure l'optique, et une métasurface peut en outre ou en variante être formée sur une partie périphérique et être configurée pour agir comme un filtre afin de réduire la transmission sur le spectre visible humain dans la partie périphérique à travers une surface antérieure périphérique de la partie périphérique.
