Abstract
Method for removing unwanted excess material from a mold section is particularly adapted for removing a monomer ring adhered within a reservoir of a female mold section used to mold a contact lens. The invention involves piercing the monomer ring and rotating the piercing members (e.g., annularly spaced pins) relative to the mold section whereby the monomer ring is sheared from the mold section to which it was adhered while the molded lens is left intact in the mold section.
