Unlike stocked silicone hydrogel contact lenses which are cast molded, custom lenses generally require high-precision lathing.
CIBA Vision material chemists invented an exciting new silicone hydrogel formulation called sifilcon A that has a unique property that allows it to be lathed.
State-of-the-art InnoLathe™ manufacturing technology.
The patented InnoLathe process creates high-precision lathe-cut silicone hydrogel lenses.
