Molding toric contact lenses using a directed stream of gas |
摘要 |
The lens is molded in a rotating concave lens mold. Liquid lens monomer is placed in the concave mold and a controlled stream of gas from a narrow opening extending across the lens and positioned over the lens center shapes the concave surface to a toric. The lens mold and the gas nozzle rotate in synchronization until the lens monomer is polymerized.
