A method of automatic manufacture of an astigmatic contact lens having a toric portion and a ballast portion such that the ballast portion causes the toric portion of the contact lens to properly orient in the eye of the wearer. The toric lenses are manufactured by moving a pallet (24) containing at least half of a casting cup assembly (26) and an information tag (27) under a filling assembly (16) and filling half of the casting cup assembly (26) with liquid monomer, moving the pallet (24) to a closing assembly (16) and, based on information obtained from the information tag (27), rotating one or both halves of the casting cup assembly (26) and closing the casting cup assembly (26). The liquid monomer is then cured thereby creating a toric contact lens.

Cette invention se rapporte à un procédé de fabrication automatique d'une lentille de contact astigmatique ayant une partie torique et une partie ballast, laquelle est conçue pour amener la partie torique de la lentille de contact à s'orienter correctement dans l'oeil. On fabrique ces lentilles toriques en déplaçant une palette (24) contenant au moins la moitié d'un ensemble coupelle de moulage (26) et une étiquette porte-informations (27) sous un ensemble de remplissage (16), et en remplissant la moitié de l'ensemble coupelle de moulage (26) avec un monomère liquide, en déplaçant la palette (24) jusqu'à un ensemble de fermeture (16) et, sur la base des informations obtenues à partir de l'étiquette porte-informations (27), en faisant tourner l'une des moitiés ou les deux moitiés de l'ensemble coupelle de moulage (26) et en fermant l'ensemble coupelle de moulage (26). On laisse ensuite durcir le monomère liquide, créant ainsi une lentille de contact torique.
