摘要： The present invention covers a method and apparatus to measure the position of an eye in up to 6 degrees of freedom, the pupil diameter and the identity of an eye in different diagnosis and treatment instruments and to link and relate the different positions measured at different times and/ or in different instruments to each other. The method used for linking and relating the position measurements to each other is a co-ordinate transformation between the different system co-ordinate systems and the eye co-ordinate system as measured by image processing or other measurement techniques to obtain either single or combined measures of degrees of freedom. In addition to the position of the eye, the identity of the eye under diagnosis or treatment can be measured and recognized in the different instruments and systems. The measurement of the eye position and pupil diameter can also be done with different measurement techniques like standard or non-standard video image analysis from one or several cameras per system, optical coherence tomography, laser interferometry or others.
