ABSTRACT:
The present invention is directed to a method of calibrating drill depth of an ophthalmic processing device. A number of drill cycles are selected for drilling an expected number of holes in a lens blank. The selected number of drill cycles is performed. The drill depth of each consecutive drill cycle varies incrementally. An actual number of locations the drill bit contacted the lens blank during the drill cycles is compared to the expected number of holes. The drill depth is adjusted depending on the compared values. A method of calibrating drill hole size is also disclosed.
