  • Patent number: 9539761
    Abstract: The present invention relates to a process and to a device for manufacturing a hybrid contact lens (7, 21), from a composite part formed of a rigid central portion connected to a soft peripheral portion (9, 23) by an adhesive material (10, 24), to such a part and to such a lens. Starting from an oxygen-permeable rigid disc (2) and from a previously hydrated hydrophilic soft disc (3), a composite part (1) comprising three superposed layers is formed by bonding one disc to the other, said composite part (1) is dried for a defined time sufficient to allow the dehydration of the soft disc, then said composite part is dry cut with a machining tool by presenting the face of the hydrophilic soft portion (3) toward the tool in order to obtain the hybrid lens, by making a release strip (26) on the outer circumference (27) of the rigid peripheral portion.

  • Patent number: 8974056
    Abstract: The invention relates to a method for making a hybrid contact lens, comprising: a step of providing a hydrophilic disc (100); a step of providing a rigid disc (200); a step of hydrating the hydrophilic disc (100); a step of applying an adhesive element (202) on a surface of the rigid disc; a step of bonding the hydrophilic disc (100) to said surface of the rigid disc; a step of drying the two thus bonded discs (100); and a step of cutting the two thus bonded and dried discs (100).
