摘要
A method for drilling an ophthalmic lens (10) includes the following steps: —memorizing the desired shape and dimensions of a drill hole (701; 702; 703) to be drilled in the ophthalmic lens (10) and the position of the opening of this drill hole on one of the faces (11, 12) of the ophthalmic lens; —positioning a drilling tool (80) facing the memorized position of the hole to be drilled; —determining a control setpoint for the transverse movement and axial advance of the drilling tool; and —drilling the ophthalmic lens according to the control setpoint. The control setpoint for the transverse movement and axial advance of the drilling tool forces the point of this drilling tool, on at least one drilling run, to follow a helical or pseudohelical trajectory depending on the desired shape and dimensions of the drill hole. An associated drilling device is also described.
