Laser system having an orientation analysis system for measuring the orientation of the patient

A method of operating an ophthalmic laser system having a beam delivery system, for performing laser treatments of an eye of a patient using a treatment laser beam, the laser system comprising:

• a beam delivery system for focusing the treatment laser beam so that the treatment laser beam travels toward the eye to be treated;
• a controller operatively coupled with the beam delivery system and configured to control the beam delivery system to position a focus of the laser beam at different locations within the eye or on an anterior surface of a cornea of the eye;
• the method comprising:
• acquiring, using an orientation analysis system, orientation-related data using one or both of:
• (a) one or more body portions of the patient and
• (b) one or more objects, each of which being in a fixed position or orientation relative to a respective body portion, so that the orientation-related data depend on an orientation of the one or more body portions around an axis of the eye;
• wherein at least one of the body portions is outside the eye to be treated.

A method of operating an ophthalmic laser system having a beam delivery system, wherein the laser system is configured to perform laser treatments on an eye of a patient using a treatment laser beam, the laser system comprising:

• a beam delivery system for focusing the treatment laser beam so that the treatment laser beam travels toward the patient's eye;
• a controller operatively coupled with the beam delivery system and configured to control the beam delivery system to position a focus of the laser beam at different locations within the eye or on an anterior surface of a cornea of the eye;
• a guide configured to allow moving at least a movable portion of the beam delivery system to adjust an orientation of at least the movable portion to different orientations of the patient's head measured around an axis of the eye to be treated;
• wherein the method comprises:
• indicating, using an orientation indicating system, to a user, a relative orientation between
• (a) an orientation of one or both of (i) a body portion of the patient and (ii) an object, which is in contact with or covers at least a portion of the body portion;
• and
• (b) an orientation of the movable portion of the beam delivery system, wherein the orientation is relative to an axis of the eye to be treated.
