Patent ID: 8303577

Claim:
A method for determining an actual value of at least one laser system parameter or a deviation from a desired value of the at least one laser system parameter of an eye treatment system emitting a treatment laser beam, the method comprising: ablating a surface of a calibrating body alternately or simultaneously with ablating a surface of an eye by at least one partial beam of the treatment laser beam according to a predetermined ablation program the ablating resulting in an ablated surface of the calibrating body; examining the ablated surface of the calibrating body ablated with the treatment laser beam with at least one of aberrometry or profilometry to obtain examination data; and using the examination data to determine an actual value of the at least one laser system parameter or a deviation from a desired value of the at least one laser system parameter and to adjust the at least one laser system parameter during ablating of the surface of the calibrating body and the surface of the eye.
