摘要： Progressive lens designs are provided with various features relative to the corridor width, corridor length, and relative positioning of areas of maximum gradient power progression and maximum gradient, that differ from conventional progressive lens designs. Progressive lenses according to the invention may include a “V-shaped” cylinder map, a relatively low position of maximum gradient of power progression, and/or a large vertical separation between vertical position of maximal cylinder and vertical position of maximum gradient of power progression.

摘要： A wrist implant requires minimal resection of the distal radius and preserves the sigmoid notch and articulation with the head of the distal ulna. The wrist implant generally includes a radius portion, a carpal portion and a carpal ball. The wrist implant includes a primary articulation and a secondary rotational articulation. The primary articulation occurs between the radius portion and the carpal ball. The secondary articulation occurs between the carpal ball and the carpal portion.

摘要： An apparatus for the automated production of ophthalmic lenses, particularly compound lenses having a plastic coating on a plastic lens is described. A mold, after rotational orientation, is placed in a gimbal assembly to provide for the proper tilt. This gimbal assembly forms part of a fixture attached to an indexing means which moves for complete assembly of a molding fixture and then moves the molding fixture through a chamber to cure the resin. A preform, after rotational orientation, is held, by a preform gripper placed above the mold, and with sufficient clearance between the mold and the preform to allow the correct resin thickness during the curing portion of the process. The fixture is also provided with members to firmly grip the preform gripper so as to maintain its orientation throughout the curing process.

摘要： The invention provides progressive addition lenses in which lens unwanted astigmatism is reduced and channel width through the intermediate and near vision zones is increased as compared to conventional progressive addition lenses. This result is achieved by combining a progressive addition surface with a first dioptric add power with at least one optical element that provides additional dioptric add power to the lens.
