ABSTRACT:
An apparatus for filling and assembling mold parts for a contact lens includes a first automated station for receiving a plurality of front curve contact lens mold parts and depositing in each front curve mold a predetermined amount of a polymerizable monomer or monomer mixture, and, a second automated station for receiving the plurality of front curve mold parts and assembling each front curve mold part with a back curve mold part under vacuum to prevent entrapment of gas between the mold parts. The front curve mold parts are transported to the first and to the second automated stations by a pallet having registration guides that cooperate with the second station to register the pallet prior to assembly of the mold parts.
