Digital (also called Direct) Surfacing refers to the manufacturing process by which an atoric design is ground onto the back surface of a standard semi-finished lens blank. This could be a progressive curve ground onto the back of a SFSV blank, or an atoric surface ground into the back of a semi-finished progressive blank to optimize the design for the patient, or some other combination of curves.
Processing digital surface designs in a lab involves the use of a Digital Surfacing (or Lens Design System, herein called the LDS) calculation program, provided by the LDS vendor, and equipment specially designed to cut these surfaces into a lens, both of which must interface with the lab management software (LMS) used by the lab.
