Latest Patents

Joseph E. Janca holds a patent for an "Annular gated mold for the injection molding of contact lenses." This invention describes a method and apparatus for the manufacture of optical polymer contact lenses using a closed mold. The design features a mold cavity created between a front curve insert and a back curve insert. The side walls of the mold cavity are formed by the inner wall of a movable annular gate collar. This collar is positioned in a retracted position during polymer dosing and is then moved to an extended position prior to polymer cure. This innovative design effectively separates the polymer curing inside the mold cavity from any waste polymer outside of it.
