Intra=ocular lens implant with radiating haptic arms - has central lens portion, with two diametrically-opposed strands configured as double arcs, outer arc not being centred on centre of lens

The lens implant (1) has optical lens (2) and haptic (4) portions, the latter consisting of two diametrically-opposite locating strands (5,6). The strands each include a bearing portion (5b,6b) shaped as a circular arc centred on a point (60) different from the centre (7) of the optical lens. The ce...

More Information
Summary:The lens implant (1) has optical lens (2) and haptic (4) portions, the latter consisting of two diametrically-opposite locating strands (5,6). The strands each include a bearing portion (5b,6b) shaped as a circular arc centred on a point (60) different from the centre (7) of the optical lens. The centre of this arc is located in the anterior quadrant (8) of the lens. The remaining reference quadrants (9) of the lens entirely contain the intermediate portions (5a,6a) of the strands. USE/ADVANTAGE - Simplified implantation procedure for intra-ocular lens to replace crystalline lens, without loss of flexibility of haptic portion. Implant (1) intra-oculaire de chambre postérieure comprenant: - une partie optique (2) - et une partie haptique (4) comprenant deux anses (5, 6) diamétralement opposées, comportant chacune un segment (5a, 6a) de rattachement, de trajet s'éloignant progressivement de la partie optique, et un segment (5b, 6b) d'appui de profil circulaire, et de trajet en sens différent à celui du segment de rattachement caractérisé en ce que le segment d'appui (5b, 6b) a un profil substantiellement en arc de cercle centré sur un point (60) différent du centre (7) de la partie optique, situé dans le quadrant antérieur (8) délimité par un premier diamètre passant par les deux points (5d, 6d) de liaison des deux anses (5, 6) respectivement avec la partie optique (2), et un deuxième diamètre perpendiculaire au premier diamètre, ledit quadrant antérieur étant situé immédiatement avant le quadrant dit de référence (9) contenant le segment (6a) de rattachement.
