Patent ID: 7935280

Claim:
A method for forming an ophthalmic lens, comprising the steps of: providing an injection molding apparatus having a non-optical tool assembly for forming the non-optical surface of the ophthalmic lens mold section and an optical tool assembly in opposed relation to said non-optical tool assembly that together therewith forms a mold cavity for forming the ophthalmic lens mold section, said optical tool assembly includes a rotatably mounted core member; an optical insert removably secured to said core member, said optical insert having an optical molding surface for forming an optical surface of the ophthalmic lens mold section opposite the non-optical surface; and a locking mechanism selectively operable between an unlocked position and a locked position, wherein when in said unlocked position, said core member may be freely rotated, and when in said locked position said core member is in a selected rotatably fixed position; injection molding said ophthalmic lens mold section in said mold cavity; removing said molded ophthalmic lens mold section from said mold cavity; matching said ophthalmic lens mold section with a mating ophthalmic lens mold section; and cast molding an ophthalmic lens between said ophthalmic lens mold sections.
