1. A machine for processing an edge profile of an ophthalmic lens, the ophthalmic lens including first and second opposite optical surfaces and an outer peripheral edge defined therebetween, the machine defined by mutually perpendicular X, Y and Z axes, the machine comprising:
a machine frame;
a lens holder unit for selectively holding the ophthalmic lens;
a laser scanner unit for determining a profile of the outer peripheral edge of the ophthalmic lens mounted to the lens holder unit; and
a main controller operatively connected to each of the lens holder unit and the laser scanner unit for controlling and operating the lens holder unit and the laser scanner unit;
each of the lens holder unit and the laser scanner unit mounted to the machine frame;
the lens holder unit moveable relative to the machine frame between a home position holding the ophthalmic lens away from the laser scanner unit, and a working position positioning the ophthalmic lens adjacent the laser scanner unit;
the lens holder unit configured to selectively rotate the ophthalmic lens around a C-axis of the lens holder unit, tilt the ophthalmic lens relative to the laser scanner unit and move rectilinearly relative to the machine frame in the Y axis;
the laser scanner unit selectively moveable rectilinearly relative to the machine frame in the directions of the X and Z axes.
