description The present invention relates to cast molding of toric contact lenses, which include an optical zone providing a cylindrical correction for patients having certain astigmatic abnormalities. Unlike contact lenses having only a spherical correction, which may generally be placed on the eye in any rotational position, toric lenses are positioned on the patient's eye such that the optical zone's toric axis is aligned with the eye's astigmatic axis. A carrier is provided for holding a lens mold that includes a first mold half defining a first optical surface and a second mold half defining a second optical surface. A first frame defines a front surface. A holder assembly is in operative communication with the first frame and is configured to receive the first mold half. The holder assembly is adjustable to rotationally secure the first mold half so that the first optical surface faces outward from the first frame front surface and in any of a plurality of rotational positions with respect to an axis normal to the first frame front surface. A second frame is configured to receive the second mold half so that the second optical surface faces outward from a front surface of the second frame. The second frame front surface opposes the first frame front surface upon alignment of the first frame and the second frame in an operative position.
