Patent ID: 8808279

Claim:
A method of measuring and treating a transparent or semi-transparent tissue, the method comprising: providing illumination laser radiation; focusing the illumination laser radiation at a focal point in the tissue; three dimensionally scanning the tissue with the illumination laser radiation by changing the position of the focal point within the tissue in three dimensions; detecting tissue-specific signals induced by said focusing; assigning the detected tissue specific signals to respective positions of the focal point at which the tissue-specific signals were detected, wherein the respective positions of the focal point constitute points of measurement located within the tissue; determining positions of boundaries in the tissue, inclusions in the tissue or both by filtering out the points of measurement at which predefined values were detected for the tissue specific signals; defining target points within the tissue based on the points of measurement remaining after the filtering out; performing a subsequent treatment of the tissue by focusing treating laser radiation into the tissue and scanning the treating laser radiation over the target points within the tissue; wherein the illumination laser radiation and the treating laser radiation are provided from the same laser radiation source; and wherein the treating laser radiation and the illumination laser radiation are focused and scanned by the same optical elements.
