Edge radius on a toric periphery lens is perfectly feasible with the FT-3 Edge Fast Tool. Using the very latest in fast-tool servo technology and drawing on a proven track record of fast-tool functionality and tooling possibilities, this device opens the way for making lenses to fit irregular sclera.
The FT-3 Edge consists of a 3-tool arrangement for roughing, finishing and edging of non-rotationally symmetric lens types. Finishing tool life can be increased because roughed-out surfaces follow the same contour leading to a more uniform final cut. The whole irregular lens shape can be completed with a comfortable edge profile of your choosing.
