In an assembled state each retainer arm (21) of the retainer (20) engages with a corresponding one of the recesses (12) in the basket wall of the basket (10) to retain the ophthalmic lens (100) in the cavity.
Method for providing a male mold half for molding a toric ophthalmic lens at a predetermined target rotational orientation
A method of providing a male mold half for molding a toric contact lens at a predetermined target rotational orientation is disclosed. The method comprises the steps of: providing the male mold half at a predetermined rotational orientation, picking the male mold half up with a gripper having a central axis, rotating the gripper with the male mold half about the central axis of the gripper by a predetermined rotational angle (?) towards the predetermined target rotational orientation, and releasing the rotated male mold half from the gripper. Prior to picking the male mold half up, the method comprises centering the grippe and the male mold half relative to each other such that the central axis of the gripper and a central axis of the male mold half coincide.
SYSTEM AND METHOD FOR PROCESSING OF OPTICAL LENSES
