Abstract: Apparatus to treat an eye with an ophthalmic laser system comprises a patient interface having 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. Liquid is added above the eye to act as a transmissive medium. A coupling sensor is coupled to the suction line to determine coupling of the retention structure to the eye. A separate pressure monitoring circuit having a much smaller volume than the suction line is connected to the annular retention structure to measure suction pressure therein. A system processor coupled to the monitoring pressure sensor includes instructions to interrupt firing of a laser when the pressure measured with a monitoring pressure sensor rises above a threshold amount.

Abstract: An imaging system includes an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The eye interface device interfaces with an eye. The scanning assembly supports the eye interface device and scans a focal point of an electromagnetic radiation beam within the eye. The beam source generates the electromagnetic radiation beam. The free-floating mechanism supports the scanning assembly and accommodates movement of the eye and provides a variable optical path for the electronic radiation beam and a portion of the electronic radiation beam reflected from the focal point location. The variable optical path is disposed between the beam source and the scanner and has an optical path length that varies to accommodate movement of the eye. The detection assembly generates a signal indicative of intensity of a portion of the electromagnetic radiation beam reflected from the focal point location.

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: Methods and related apparatus for real-time process monitoring during laser-based refractive index modification of an intraocular lens. During in situ laser treatment of the IOL to modify the refractive index of the IOL material, a signal from the IOL is measured to determine the processing effect of the refractive index modification, and based on the determination, to adjust the laser system parameters to achieve intended processing result. The signal measured from the IOL may be a fluorescent signal induced by the treatment laser, a fluorescent signal induced by an external illumination source, a temporary photodarkening effect, a color change, or a refractive index change directly measured by phase stabilized OCT.

Abstract: A patient interface includes an eye interface device, a scanner, a first support assembly, and a beam source. The eye interface device is configured to interface with an eye of a patient. The scanner is configured to be coupled with the eye interface device and operable to scan an electromagnetic radiation beam in at least two dimensions in an eye interfaced with the eye interface device. The scanner and the eye interface device move in conjunction with movement of the eye. The first support assembly supports the scanner so as to accommodate relative movement between the scanner and the first support assembly parallel so as to accommodate movement of the eye. The beam source generates the electromagnetic radiation beam. The electromagnetic radiation beam propagates from the beam source to the scanner along an optical path having an optical path length that varies in response to movement of the eye.

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: 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.
