Abstract:
(EN) The invention relates to an artificial eye lens (1) with an optical part (2), which has a first optical side (4) as considered in the direction of a primary optical axis (A) of the eye lens (1) and an opposite, second optical side (5), wherein the optical part (2) is formed with a structure (3a) having a birefringence, wherein the birefringent structure (2a) is formed in the one-piece optical part (2) as a laser structure. The invention also relates to a method for producing an artificial eye lens (1) of this kind.
(FR) L'invention concerne un cristallin artificiel (1) comprenant un élément optique (2) qui présente un premier côté optique (4), vu dans la direction d'un axe principal optique (A) du cristallin (1), et un second côté optique (5), l’élément optique (2) étant pourvu d’une structure (2a) présentant une biréfringence, la structure biréfringente (2a) étant réalisée dans l’élément optique (2) monobloc, sous la forme d'une structure laser. L'invention concerne également un procédé de fabrication d'un tel cristallin artificiel (1).
(DE) Eine künstliche Augenlinse (1) mit einem optischen Teil (2), der eine in Richtung einer optischen Hauptachse (A) der Augenlinse (1) betrachtet erste optische Seite (4) und eine gegenüberliegende zweite optische Seite (5) aufweist, wobei der optische Teil (2) mit einer eine Doppelbrechung aufweisenden Struktur (2a) ausgebildet ist, wobei die doppelbrechende Struktur (2a) in dem einstückigen optischen Teil (2) als Laserstruktur ausgebildet ist. Die Erfindung betrifft auch ein Verfahren zum Herstellen einer derartigen künstlichen Augenlinse (1).
