Abstract[English]
In some embodiments, an optical device includes a bulk silicone hydrogel material having a convex anterior surface and an opposite concave posterior surface, a central optical zone, and one or more peripheral zones circumscribing the central optical zone. The contact lens includes an insert embedded in the bulk silicone hydrogel material having a convex anterior surface and an opposite concave posterior surface, the convex anterior surface comprising 10 or more echelettes. The optical device has a convex anterior surface and an opposite concave posterior surface. The insert includes a crosslinked silicone-containing vinyl copolymer different from a crosslinked silicone-containing vinyl copolymer of the bulk silicone hydrogel material and has a diameter up to about 10 mm. The insert is concentric with a central axis of the optical device.[French]
Dans certains modes de réalisation, un dispositif optique comprend un matériau d'hydrogel de silicone en vrac ayant une surface antérieure convexe et une surface postérieure concave opposée, une zone optique centrale et une ou plusieurs zones périphériques entourant la zone optique centrale. Une lentille de contact comprend un insert intégré dans le matériau d'hydrogel de silicone en vrac ayant une surface antérieure convexe et une surface postérieure concave opposée, la surface antérieure convexe comprenant 10 échelettes ou plus. Le dispositif optique a une surface antérieure convexe et une surface postérieure concave opposée. L'insert comprend un copolymère vinylique contenant de la silicone réticulé différent d'un copolymère vinylique contenant de la silicone réticulé du matériau d'hydrogel de silicone en vrac et a un diamètre allant jusqu'à environ 10 mm. L'insert est concentrique avec un axe central du dispositif optique.
