Title (EN) DIFFRACTIVE LENSES AND RELATED INTRAOCULAR LENSES FOR PRESBYOPIA TREATMENT
(FR) LENTILLES DIFFRACTIVES ET LENTILLES INTRAOCULAIRES ASSOCIÉES POUR LE TRAITEMENT DE LA PRESBYTIE
Abstract:
(EN) Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (lOLs), include features for reducing dysphotopsia effects, such as straylight, haloes and glare, in diffractive lenses. Exemplary ophthalmic lenses can include a diffractive profile (600) that distributes light among a near focal length, a far focal length, and one or more intermediate focal length. The diffractive profile provides for minimized or zero step heights between one or more pairs of diffractive zones (606, 608) for reducing visual artifacts.
(FR) L'invention concerne des appareils, des systèmes et des procédés permettant de fournir des lentilles ophtalmiques améliorées, en particulier des lentilles intraoculaires (LIO), dont les caractéristiques permettent de réduire les effets de dysphotopsie, tels que la lumière parasite, les halos et l'éblouissement, dans les lentilles diffractives. Des lentilles ophtalmiques données à titre d'exemple peuvent comprendre un profil diffractif (600) qui répartit la lumière en une longueur focale proche, une longueur focale éloignée et une ou plusieurs longueurs focales intermédiaires. Le profil diffractif fournit des hauteurs de paliers réduites au minimum ou nulles entre une ou plusieurs paires de zones diffractives (606, 608) pour réduire les artéfacts visuels.
