Abstract: A manufacturing module (MM) for contact lenses comprises a plurality of manufacturing stations (300, 301, 302, 310, 320, 321, 322, 330, 331, 340, 341, 342, 350, 351, 352) arranged in a closed loop and a plurality of lens mold carriers (1, 2) which are transported through the manufacturing stations. Each lens mold carrier (1, 2) comprises a frame (10, 20) having a predetermined number of mounting sites (100, 200) arranged along the frame. Each lens mold carrier (1, 2) further comprises a predetermined number of molds (112, 212) removably mounted to the frame (10, 20) at the mounting sites (100, 200), the molds being reusable male or female molds (212, 112). Two lens mold carriers (1, 2) are assigned to each other to form a pair, so that upon mating the pair of lens mold carriers (1, 2) the male and female molds (212, 112) are mated to form mold cavities defining the shape of the lenses. The manufacturing stations comprise a mold changing station (300, 301, 302) configured to be capable of removing a mold from its mounting site (100, 200) and mounting a different mold at the said mounting site (100, 200), or configured to change the rotational position of a mold (112, 212) mounted to the frame (10, 20), or both.

Abstract: There is described a method of separating excess lens forming material from a molded ophthalmic lens, in particular a contact lens. After polymerization and/or cross-linking of a lens forming material (P) within a mold cavity (4) of a mold (1) comprising female and male mold halves (2, 3) to form an ophthalmic lens non-polymerized and/or non-cross-linked lens forming material is flushed away from the mold halves (2, 3) with a jet of a fluid flushing medium, such as, e.g., water or a solvent or an inert gas. Subsequently the molded lens is dried. In accordance with the invention the flushing is accomplished with the mold halves (2, 3) still in the closed position. There is also described an apparatus for carrying out the method.
