Abstract[English]
The current disclosure relates to methods of designing a front surface toric soft contact lens with a substantially circular optic zone. More specifically, this disclosure describes a method to design a front surface toric soft contact lens which features a substantially circular optic zone with smooth transitions between the optic zone and the peripheral non-optical stabilisation carrier zone. The optic zone diameter is designed independent of the cylinder power and the shape, or curvature, of the back surface. This disclosure describes a method to design a front surface toric soft contact lens such that neither the edge profile nor the optic zone diameter is affected by the magnitude of cylinder power or the orientation of the cylinder axis.[French]
La présente divulgation concerne des procédés de conception d'une lentille de contact souple torique de surface avant avec une zone optique sensiblement circulaire. Plus spécifiquement, la présente divulgation concerne un procédé de conception d'une lentille de contact souple torique de surface avant qui présente une zone optique sensiblement circulaire avec des transitions lisses entre la zone optique et la zone de support de stabilisation non optique périphérique. Le diamètre de la zone optique est conçu indépendamment de la puissance du cylindre et de la forme ou de la courbure de la surface arrière. La présente divulgation concerne un procédé de conception d'une lentille de contact souple torique de surface avant de telle sorte que ni le profil de bord ni le diamètre de zone optique ne sont affectés par l'amplitude de puissance de cylindre ou l'orientation de l'axe de cylindre.
