1. A system for ophthalmic intervention on an eye of a patient having temporary geometric markers thereon indicative of the orientation of an astigmatic axis of the patient's eye, comprising: a. an imaging device having a field of view oriented toward the eye of the patient, the imaging device configured for generating 3-dimensional images of the field of view;b. a patient interface housing having proximal and distal ends and defining a passage therethrough, wherein the distal end is coupled to one or more seals around a periphery of the passage configured to be directly engaged with an exterior surface of the eye of the patient and having a size sufficient to render visible the temporary geometric markers on the eye in that the temporary geometric markers are within the field of view of the imaging device, and wherein the proximal end is configured to be coupled to the patient workstation such that at least a portion of the field of view of the imaging device passes through the passage;c. three or more registration fiducials formed on an inner annulus of the patient interface housing within the field of view of the imaging device such that they may be imaged by the imaging device in reference to the temporary geometric markers on the eye of the patient;d. control electronics operatively coupled with the image device and configured to process 3-dimensional image data generated via the image device for the three or more registration fiducials and the temporary geometric markers on the eye of the patient to determine a position, a pitch, a roll and a yaw of the patient interface device relative to the geometric markers. 2. The system of claim 1, further comprising a laser system operatively coupled to the control electronics, wherein the laser system is configured to produce a treatment beam that may be directed through the passage of the patient interface housing and into the eye of the patient. 3. The system of claim 2, wherein the treatment laser beam is suitable for creating a dielectric breakdown within a cataractous crystalline lens of the eye. 4. The system of claim 3, wherein the treatment laser beam is a pulsed treatment beam with a pulse repetition rate between about 1 kHz and about 200 kHz. 5. The system of claim 3, wherein the treatment laser beam has a wavelength between about 800 nm and about 1,100 nm. 6. The system of claim 3, wherein the treatment laser beam is a pulsed treatment beam having a pulse energy between about 1 microjoule and about 1,000 microjoules. 7. The system of claim 3, wherein the treatment laser beam is a pulsed treatment beam with a pulse duration between about 100 femtoseconds and about 10 picoseconds. 8. The system of claim 1, further comprising an illumination source configured to direct illumination radiation from a position adjacent the imaging device toward the eye of the patient. 9. The system of claim 8, wherein the illumination source is configured to direct at least a portion of the illumination radiation through the passage of the patient interface housing. 10. The system of claim 8, wherein at least a portion of the patient interface housing is translucent to the illumination radiation, and wherein the illumination source is configured to direct at least a portion of the illumination radiation across the translucent portion of the patient interface housing toward the eye of the patient. 11. The system of claim 8, wherein the illumination radiation is infrared radiation. 12. The system of claim 11, wherein the fiducials comprise one or more materials that fluoresce in infrared radiation. 13. The system of claim 11, wherein the fiducials comprise one or more materials that highly contrast in infrared radiation relative to other surrounding materials. 14. The system of claim 11, wherein the fiducials comprise one or more surface irregularities relative to other surrounding surfaces. 15. The system of claim 14, wherein the one or more surface irregularities are selected from the group consisting of: a concave feature, a convex feature, a depressed edge, a depressed step, a projecting edge, a projecting step, and an intersection of lines. 16. The system of claim 8, wherein the illumination radiation is visible light radiation. 17. The system of claim 16, wherein the fiducials comprise one or more materials that highly contrast in visible light radiation relative to other surrounding materials. 18. The system of claim 17, wherein the fiducials comprise one or more surface irregularities relative to other surrounding surfaces. 19. The system of claim 18, wherein the one or more surface irregularities are selected from the group consisting of: a concave feature, a convex feature, a depressed edge, a depressed step, a projecting edge, a projecting step, and an intersection of lines. 20. The system of claim 1, wherein the imaging device comprises an optical coherence tomography system configured to measure the coherence of radiation scattered into an interferometer from the field of view. 21. The system of claim 20, wherein the fiducials comprise one or more surface irregularities relative to other surrounding surfaces. 22. The system of claim 21, wherein the one or more surface irregularities are selected from the group consisting of: a concave feature, a convex feature, a depressed edge, a depressed step, a projecting edge, a projecting step, and an intersection of lines. 23. The system of claim 1, wherein the inner annulus is adjacent a distal end of the patient interface housing. 24. The system of claim 23, wherein the three or more fiducials includes a first, a second and a third fiducial, wherein the first and second fiducials are positioned at opposite sides of the inner annulus and the third fiducial is positioned at 90 degrees from each of the first and second fiducial. 25. The system of claim 1, wherein the control electronics are further configured to process the image data to determine a geometric relationship between an anatomical feature of the eye and the imaging device based on a geometric relationship between the three or more fiducials and the geometric markers. 26. The system of claim 25, wherein the imaging device is an Optical Coherence Tomography imaging device. 27. The system of claim 25, wherein the control electronics are further configured to process the image data to determine whether the orientation of patient interface device is at a predetermined orientation with respect to a feature of the eye.
