Patient interface for ophthalmologic diagnostic and interventional procedures

摘要

A method for ophthalmic intervention on an eye of a patient includes: imaging a first and a second registration fiducial in reference to temporary geometric markers on the eye of the patient, the registration fiducials being formed on an inner annulus of a patient interface housing within a field of view of an imaging device; imaging a third registration fiducial formed on the inner annulus of the patient interface housing, the third registration fiducial being angularly spaced from the first and second registration fiducials; and processing image data generated via the image device so as to determine an angular orientation of the eye relative to the patient interface housing and an up or down orientation of the patient interface housing relative to the eye based on the location of the third registration fiducial.

1. A method for ophthalmic intervention on an eye of a patient having temporary geometric markers thereon indicative of the orientation of axis of the patient's eye, comprising:
a. imaging a first and a second registration fiducial in reference to the temporary geometric markers on the eye of the patient, the first and second registration fiducials being formed on an inner annulus of a patient interface housing within a field of view of an imaging device; d. imaging a third registration fiducial formed on the inner annulus of the patient interface housing within the field of view of the imaging device such that it may be imaged by the imaging device, the third registration fiducial being angularly spaced from both the first and second registration fiducials; and c. processing image data generated via the image device for the first, second and third registration fiducials and the temporary geometric markers on the eye of the patient so as to determine an angular orientation of the eye relative to the patient interface housing and an up or down orientation of the patient interface housing relative to the eye based on the location of the third registration fiducial.
