摘要： An improved, automated method and apparatus for molding contact lenses generally comprises the steps of: (1) forming anterior (20) and posterior (18) mold cavities in longitudinally spaced relation in first and second webs (10, 12) of material, respectively; (2) dispensing a liquid, curable, lens material (e.g., monomer) in each anterior cavity of the first web; (3) aligning and bringing the posterior and anterior cavities into sequential, mating, centered engagement with each other; (4) curing the lens material captured between respective posterior and anterior molds; and (5) separating the webs to release the lenses (34) cast therebetween. In an advantageous embodiment of the invention, the mold cavities are vacuum-formed in the respective webs, and packaging receptacles (40) are formed in one or both of the webs used to mold the lenses.
