Реферат: The invention enhances the alignment between the eye (E), and a laser beam (14) of a laser eye surgery system (10) using a visual fixation system (38), the fixation system (38) often having an adjustable optical train (58). The optical train (58) of the fixation system (38) allows an eye (E) having a significant refractive error to be accurately focused at a fixation target (60). To accommodate the refractive error, the adjustable optical train (58) will often project an image of the target (60) so that the projected image is in focus in front of or behind the plane of the patient's eye (E). The present invention also encompasses the calculation of the proper projection distance to accommodate the refractive error of the eye (E), the calculation preferably based at least in part on the eye glass prescription for that eye (E).
