    Abstract: A method for measuring the intraocular pressure (IOP) of an eye docked to an ophthalmic surgical laser system via a patient interface assembly. While the eye is docked to the laser system, and as the vertical force exerted on the eye by the patient interface fluctuates as the patient breaths and moves, the amount of corneal deformation is continuously measured by an optical coherence tomography device of the laser system and the force exerted on the eye is continuously measured by force sensors integrated in the patient interface assembly. Based on the real-time force signal and real-time corneal deformation signal, a controller calculates a linear relationship between force and corneal deformation, and determines the IOP of the docked eye by comparing a slope of the linear relationship against a pre-established slope vs. IOP calibration curve. The IOP of the docked eye can be used when setting laser treatment parameters.

    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: The patient interface may comprise an axis for alignment with an axis of the eye such as an optical axis of the eye. The interface may comprise a guide to allow the interface to move along the axis with the eye, which can inhibit increases in intraocular pressure when the patient is aligned with the laser. The interface may comprise a lock to hold the patient interface at a location along the axis, which can maintain alignment of the patient with the laser eye surgery system. The interface may comprise a plurality of transducers to measure forces to the eye during surgery. The laser eye surgery system can be configured in one or more of many ways to respond to the measured forces. For example, the system may offset the position of laser beam pulses to increase the accuracy of the placement of the beam pulses on the eye.

    Abstract: Apparatus to treat an eye comprises an annular retention structure to couple to an anterior surface of the eye. The retention structure is coupled to a suction line to couple the retention structure to the eye with suction. A coupling sensor is coupled to the retention structure or the suction line to determine coupling of the retention structure to the eye. A fluid collecting container can be coupled to the retention structure to receive and collect liquid or viscous material from the retention structure. A fluid stop comprising a porous structure can be coupled to an outlet of the fluid collecting container to inhibit passage of the liquid or viscous material when the container has received an amount of the liquid or viscous material. The coupling sensor can be coupled upstream of the porous structure to provide a rapid measurement of the coupling of the retention structure to the eye.

    Abstract: A method for laser eye surgery that accommodates patient movement includes: generating a first and a second electromagnetic radiation beam, the second beam configured to modify eye tissue; propagating the first beam to a scanner along a an optical path length that changes in response to eye movement; focusing the first beam to a first focal point within the eye; scanning the first focal point at different locations within the eye; propagating a portion of the first beam reflected from the first focal point location back along the variable optical path to a sensor; generating an intensity signal indicative of the intensity of the portion of the reflected first beam; propagating the second beam to the scanner along the variable optical path; focusing the second beam to a second focal point and scanning the second focal point to create an incision in the cornea of the eye.
