Claim:
1. A method for ophthalmic intervention on an eye of a patient, comprising: a. orienting a field of view of an imaging device toward the eye of the patient; b. coupling a distal end of a patient interface housing to one or more seals configured to be directly engaged with one or more surfaces of the eye of the patient, and coupling a proximal end of the patient interface housing to a patient workstation such that at least a portion of the field of view of the imaging device passes through a passage of the patient housing defined by the proximal and distal ends; c. imaging, within the field of the view of the imaging device, three or more registration fiducials, which include first and second registration fiducials coupled to the patient interface housing in a predetermined geometric configuration relative to the patient interface housing in reference to predetermined geometric markers on the eye of the patient, which are also imaged by the imaging device; and d. processing imaging data generated via the imaging device so as to determine an angular orientation of the eye relative to the patient interface based on the first and second fiducial and the predetermined geometric markers and also to determine an up or down orientation of the patient interface housing relative to the eye based on the location of a third fiducial.
