    IPC: A61F9/009

    Abstract: Apparatus and method for interfacing an ophthalmic surgical laser system with a patient's eye using a single-piece patient interface (PI). The PI includes a hollow shell, with an applanation lens and a flexible skirt at its lower end. Through channels are formed around the applanation lens to connect the spaces above and below the lens. When the PI is coupled to the laser system and the eye, the upper rim of the shell forms a seal with the laser system and the flexible skirt forms a seal with the eye. A vacuum is applied to the interior of the shell via a vacuum port on the laser system, and the vacuum is communicated to the space enclosed by the applanation lens, the skirt and the eye through the channels around the lens. A magnetic mechanism is also provided to hold the PI shell to the laser system.

    Abstract: A single-piece patient interface device for coupling a patient's eye to an ophthalmic surgical laser system includes a cone substrate with a rigid frustoconical shaped shell for coupling to the laser system, and a flexible suction ring integrally joined to the lower end of the rigid shell for coupling to the patient's eye. The suction ring has a circular skirt extending downwardly from a base portion, a diaphragm extending from the base portion and disposed inside of the skirt, and a contact lens held by the diaphragm to cover a center opening. When the skirt contacts the eye's surface, the skirt, the diaphragm, the contact lens and the eye surface form a vacuum chamber, where a vacuum may be applied to secure the patient interface device to the eye. The parameters of the suction ring are optimized to fit a large range of eye sizes, including smaller eyes.

    Abstract: In a femtosecond laser eye surgery system where beam delivery is accomplished with a moving objective, a dual-channel imaging system allows real-time procedure visualization before and during incision. The first (docking) imaging channel covers a full field of view (FoV) of the eye, e.g., 13 mm; the second (cutting) imaging channel is through the objective and moves with it, and covers a smaller FoV, e.g., 2 mm. During eye docking and undocking, the objective is moved to a parking position out of the visual field of the docking imaging channel, and the latter operates to provide process visualization. During incision, a composite eye image is displayed, composed of a stationary image captured by the docking imaging channel before treatment began overlayed with live cutting images captured by the cutting imaging channel. The live cutting images are compared to the stationary image in real time to detect eye movement.

    IPC: A61F9/008

    Abstract: A photo detector is selectively coupled to a first integrator or a second integrator with switching circuitry when the laser pulses. An integration time of the signal from the photo detector can be substantially greater than an amount of time between successive laser beam pulses in order to provide an accurate measurement of each laser beam pulse of a high repetition rate pulsed laser. The laser may comprise a clock coupled to an optical switch of the laser system, and control circuitry can control switching and coupling of the detector to the first integrator or the second integrator in response to the clock signal. The first integrator and the second integrator can be selectively coupled to an output such that the first integrator or the second integrator is coupled to the output of the energy detection circuitry when the other integrator is coupled to the detector.

    Abstract: A laser system is calibrated with a tomography system capable of measuring locations of structure within an optically transmissive material such as a tissue of an eye. Alternatively or in combination, the tomography system can be used to track the location of the eye and adjust the treatment in response to one or more of the location or an orientation of the eye. In many embodiments, in situ calibration and tracking of an optically transmissive tissue structure such as an eye can be provided. The optically transmissive material may comprise one or more optically transmissive structures of the eye, or a non-ocular optically transmissive material such as a calibration gel in a container or an optically transmissive material of a machined part.

    Abstract: An ophthalmic laser surgical system has a built-in imaging sensor for measuring laser focal spot size. An objective lens focuses the laser beam to a focal spot near a reflective surface, scans the focal spot in the depth direction, and focuses light reflected by the reflective surface to form a back-reflected light. A two-dimensional imaging sensor receives a sample of the back-reflected light to generate images of the back-reflected light. During the depth scan, the image contains a well-focused light spot when the laser focal spot is located at a fixed offset distance before the reflective surface, but the light spot in the images is otherwise defocused. The images generated during the scan are analyzed to find the smallest light spot size among the images. The laser focal spot size is then calculated from the smallest light spot size using a magnification factor which is a system constant.

    Abstract: In laser-assisted corneal lenticule extraction procedures, the lenticule incision profile includes anterior and posterior lenticule incisions, with one or more of the following features: plano transition zone outside the optical zone, to improve mating of anterior and posterior incision surfaces after lenticule extraction; shallow arcuate incisions above the anterior incision and near the lenticule edge, to improve surface mating; separate ring cut intersecting the anterior and posterior incisions in the transition zone, to reduce tissue bridges and minimize tear at the lenticule edges and facilitate easy lenticule extraction; larger posterior incision, which includes a pocket zone outside the lenticule edge, for better surface mating and bubble management during cutting; and a separate ring shaped pocket cut intersecting the pocket zone of the posterior incision, for bubble management. An entry cut can intersect either the pocket zone of the posterior incision or an entry extension zone of the anterior incision.
