Abstract

Une lentille intra-oculaire artificielle et destinée à être utilisée en ophtalmologie pour corriger l'amétropie comprend: un composant optique (1), des éléments de support (2) ainsi que des canaux moulés (3) destinés à fixer les éléments de support (2), lesdits canaux étant formés par deux ouvertures en intercommunication (4 et 5). L'ouverture (4) débouche sur le composant optique, tandis que l'ouverture (5) débouche sur la surface latérale (6) de la lentille, et présente une section de forme allongée suivant la surface principale de la lentille. La partie (7) de l'élément de support (2) situé dans ladite ouverture (5) présente une section transversale identique à celle de cette dernière (5). L'ouverture (4) située dans la région de raccordement avec l'ouverture (5) présente une superficie de section transversale égale ou supérieure à celle de l'ouverture (5). Cet agencement permet de monter les éléments de support (2) solidement dans le canal (3), et de réduire l'épaisseur du composant optique de la lentille.
