Abstract: System for determining a position of a tool-point-of-interest of a tool, relative to an eye-tissue-of-interest, which includes and imager a tool-tracker and a processor. The imager acquires an image of a tissue-reference-marker. The tool-tracker determines information relating to the P&O of the tool in a reference-coordinate-system. The imager and the tool-tracker are in registration with the reference-coordinate-system. The processor determines the position of the tissue-reference-marker in the reference-coordinate-system, according to the acquired image of the tissue-reference-marker. The processor determines the P&O of the eye-tissue-of-interest in the reference-coordinate-system according to at least the position of the tissue-reference-marker and a relative position between the tissue-reference-marker and the eye-tissue-of-interest. The relative position is pre-determined from a stored-3D-model. The processor determines the position of a tool-point-of-interest in the reference-coordinate-system from the P&O of the tool in the reference-coordinate-system. The processor also determines a relative position between the tool-point-of-interest and the eye-tissue-of-interest.

Abstract: System and method for determining the position and orientation (P&O) of a tool-tip relative to an eye tissue of interest. The system includes and imaging and tracking module coupled with a processor. The imaging and tracking module at least includes an imager. The imager acquires at least one image of at least one tissue-reference-marker. The imaging and tracking module further determines information relating to the P&O of the tool. The processor determines the P&O of the tissue-reference-marker according to the acquired image of the tissue-reference-marker. The processor determines the P&O of the eye tissue of interest, according to the P&O of the tissue-reference-marker, and a predetermined relative P&O between the tissue-reference-marker and the eye tissue of interest. The processor also determines the P&O of a tool-tip according to a tool-marker and determines the relative P&O between the tool-tip and the eye tissue of interest.
