Methods and apparatus are provided for making an ophthalmic lens. Apparatus are provided for filling contact lens shaped cavities of contact lens molding assemblies (40). Methods of coupling and fusing contact lens mold sections are also provided and generally include providing first and second mold sections (42a, 42b; 140; 240; 340) which when coupled together are effective to form a lens-shaped cavity and contact regions between the mold sections. One or both of the mold sections 42a, 42b; 140; 240; 340) may include one or more recessed regions (171) or projections (60; 160; 260; 360) which provide areas of non-fusion and areas of fusion, respectively, when the mold sections 42a, 42b; 140; 240; 340) have been filled with a contact lens precursor material and are fused together, for example, by means of focused ultrasound energy. |
