Abstract
A method for tracking multiple SKUs of ophthalmic devices in a manufacturing line, comprises the steps of: assembling first molding devices, at least one of the first molding devices having an identification device, such as, a bar-code or an inductive transmitting/receiving device; reading the identification device of the first molding devices; forming first molded parts using the first molding devices; providing a plurality of carriers, the carriers having carrier indicators; transferring the first molded parts to at least one of a plurality of carriers; reading the carrier indicator of the carrier carrying the first molded parts; and storing in machine-accessible memory the information associated with the identification device of the first molding devices and the information associated with the carrier indicator of the carrier carrying the first molded parts.
