The starting point for any cast moulding process is the insert. The CL TECH edge is carefully and controllably cut into the insert.

Rigorous metrology is then undertaken to ensure the insert, and hence the plastic mould, and ultimately the dry, cured contact lens are all within specifications to 0.001mm

The lenses can then be safely stored , or even transported to a separate site, in their moulds awaiting wet processing.
