Abstract:
1. A system for positioning an eye of a patient comprising: a reflectometer for determining an actual distance of a corneal apex of an eye of a patient relative to an aperture of a laser system from an input comprising a reflected beam from the corneal apex, the reflectometer calibratable to a desired position of the corneal apex; a comparator in signal communication with the reflectometer for calculating from the input and a reference beam calibrated to the desired position of the corneal apex a difference between an actual position and the desired position of the corneal apex; and a device in signal communication with the comparator for receiving a control loop signal from the comparator and moving the patient a distance in a direction for matching the actual position to the desired position of the corneal apex in response to the control loop signal.
