Abstract
A corneal marking system, and methods for its use, has a tilt-detecting device attached to a corneal marker, adapted to produce a signal when the corneal marker is in a horizontal position. Use of measurement devices may be coordinated between the marker and a level-measuring device positioned on a patient's head. Devices capable of measuring one, two or three axes are used and processors are provided to evaluate the data produced by the devices and provide a physician with a signal that the positions of the patient's head and the marker are such that an accurate marking procedure can be performed.
