Abstract: An automated production line for the production of ophthalmic lenses comprises:
a production line front end comprising: a first and a second injection-molding machine, a casting module, a filling station and a capping station, a stacking module and a curing module, a destacking module and a demolding and delensing module a production line back end comprising:
a treatment module,
an inspection module,
wherein self-driving shuttles in the inspection module can form a queue and act as a buffer for the primary packaging module if an interruption of the primary packaging module and variations of the cycle time in the primary packaging module are buffered so that the extraction module is able to operate largely independently from the upstream and downstream components of the manufacturing line.

Abstract: An injection molding apparatus for manufacturing an ophthalmic lens mold having a front surface comprising a lens forming portion and a rear surface, comprises a first molding tool and a second molding tool. The first and second molding tools are movable towards and away from each other between a closed position and an open position. In the closed position the first mold forming portion of the first molding tool and the second mold forming portion of the second molding tool define a cavity between them corresponding in shape to the shape of the ophthalmic lens mold. The surface of the second mold forming portion, at least in a central zone thereof, has a surface roughness Sa in the range of 0.3 μm to 2 μm, and a surface roughness Sz in the range of 10 μm to 50 μm.

Abstract: 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 (α) 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.

Abstract: A mold unit (22) for molding ophthalmic lenses comprises: an adapter piece (220) comprising an opening (2200) extending around a longitudinal axis (2201); a sleeve (221) fixedly connected to the adapter piece (220) and extending through the opening (2200) of the adapter piece (220); a lens mold (222) rigidly mounted to the sleeve (221); an adjustment ring (224) firmly attached to the sleeve (221) to circumferentially surround a portion of the sleeve (221). The adjustment ring (224) comprises a flat circular outer engagement surface (2244), and the adapter piece (220) comprises at least one clamping block (2211) having a flat inner clamping surface (2214). The flat inner clamping surface (2214) frictionally clamps the flat circular outer engagement surface (2244) to prevent inadvertent rotation of the sleeve (221) relative to the adapter piece (220) but to allow rotation of the sleeve (221) relative to the adapter piece (220) upon the application of a torque higher than a predetermined threshold torque.
