Abstract:
1. A device for establishing a predetermined contact alignment between an eye of a patient and a laser system during ocular surgery which comprises: at least one detector for detecting a spatial position of the eye and a spatial position of the laser system; a controller means for determining an alignment difference between the spatial position of the eye and the spatial position of the laser system; a means for altering the alignment difference between the eye and the laser system to establish the predetermined contact alignment; a means for engaging the eye with the laser system to hold the eye stationary relative to the laser system to maintain the predetermined contact alignment; at least three pressure sensors mounted on the laser system for direct contact with the eye to individually measure a respective contact pressure on the eye during contact between the eye and the laser system; and a computer means for calculating a pressure differential between each sensor and each other sensor, wherein the altering means is activated by the computer means to establish predetermined pressure differentials.
