    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: A laser eye surgery system focuses light along a beam path to a focal point having a location within a lens of the eye. The refractive index of the lens is determined in response to the location. The lens comprises a surface adjacent a second material having a second refractive index. The beam path extends a distance from the surface to the focal point. The index is determined in response to the distances from the surface to the targeted focal point and from the surface to the actual focal point, which corresponds to a location of a peak intensity of an optical interference signal of the focused light within the lens. The determined refractive index is mapped to a region in the lens, and may be used to generate a gradient index profile of the lens to more accurately place laser beam pulses for incisions.

    Abstract: Methods and apparatus are configures to measure an eye without contacting the eye with a patient interface, and these measurements are used to determine alignment and placement of the incisions when the patient interface contacts the eye. The pre-contact locations of one or more structures of the eye can be used to determine corresponding post-contact locations of the one or more optical structures of the eye when the patient interface has contacted the eye, such that the laser incisions are placed at locations that promote normal vision of the eye. The incisions are positioned in relation to the pre-contact optical structures of the eye, such as an astigmatic treatment axis, nodal points of the eye, and visual axis of the eye.
