Abstract
An automated method and apparatus is provided to mold, cure and package soft contact lenses. A conveyor system transports an array of molds through a plurality of automated work stations. The front curve mold halves are partially filled with a polymerizable monomer or monomer mixture and assembled and clamped to displace any excess hydrogel from the mold cavity. The assembly is precured and then transported through a cure station using UV radiation to complete polymerization, The assemblies are then pried apart in an automated station, with any excess monomer adhering to the removed mold half. The newly molded lens is then hydrated and separated from the front curve mold half in a hydration station. Following hydration the array of lens is automatically deposited into a plurality of packages with a robotic transfer device having a plurality of figures which transfer the lenses.
