Abstract
Methods, systems, and apparatus for removing flash from contact lens mold members are described. Flash is removed from contact lens mold members by cutting the flash from the mold member. The flash is removed by rotating a deflashing element or rotating a mold member, or both. After the flash is removed, the unfinished contact lens attached to the mold member can be further processed, which may include cutting an optical surface onto the contact lens.
