    Abstract: A full depth ophthalmic surgical system includes a femtosecond laser source and an optical coherence tomographer. The system is capable of performing surgical procedures along the entire length of the eye from the cornea to the retina. The optical system of the ophthalmic surgical system is optimized to focus the laser beam and imaging light in the vitreous humor of the eye. In some embodiments, the illumination light source and the scanning mirrors are imaged by the system's objective lens and the patient interface lens to locations near the pupil, to increase the volume of the vitreous humor reachable by the illumination light and laser beam. For procedures performed posterior to the lens, a method for calibrating the full depth ophthalmic surgical system is also provided. The system can be used to perform treatment in the vitreous humor, including treating floaters and liquification of the vitreous humor.

    Abstract: An ophthalmic system may comprise an imaging device having a field of view oriented toward the eye of the patient; a patient interface housing defining a passage therethrough, having a distal end coupled to one or more seals configured to be directly engaged with one or more surfaces of the eye of the patient, 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; and two or more registration fiducials coupled to the patient interface housing in a predetermined geometric configuration relative to 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 predetermined geometric markers on the eye of the patient which may also be imaged by the imaging device.

    Abstract: During a process of refractive index modification of an intraocular lens (IOL) using an ophthalmic laser system, optical position monitoring of the IOL is performed by a video camera system viewing the top surface of the IOL. Fiducials are incorporated into the IOL at manufacture, or created in-vivo with laser. The monitoring method employs a defined area of interest (AOI) to limit the number of pixels to be analyzed, to achieve adequately high acquisition speed. In one example, the AOI contains 5 camera scan line segments, each line segment having sufficient pixels to create a stable amplitude signature. Successive frames of the AOI are analyzed to detect movement of the fiducial and/or to determine whether the fiducial has been lost.

    Abstract: A method of performing laser surgery in a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form an enclosed treatment pattern that is configured to form an enclosed capsulorhexis incision that includes a registration feature, and delivering the enclosed treatment pattern to target tissue in the patient's eye to form in an anterior lens capsule of the patient's eye the enclosed capsulorhexis incision that includes the registration feature. The registration feature is configured so that an edge of the target tissue formed by the enclosed capsulorhexis incision mates with an intraocular lens registration feature on an intraocular lens so as to rotationally register the intraocular lens relative to the registration feature.
