    Abstract: Systems and methods automatically locate optical surfaces of an eye and automatically generate surface models of the optical surfaces. A method includes OCT scanning of an eye. Returning portions of a sample beam are processed to locate a point on the optical surface and first locations on the optical surface within a first radial distance of the point. A first surface model of the optical surface is generated based on the location of the point and the first locations. Returning portions of the sample beam are processed so as to detect second locations on the optical surface beyond the first radial distance and within a second radial distance from the point. A second surface model of the optical surface is generated based on the location of the point on the optical surface and the first and second locations on the optical surface.

    Abstract: A method of imaging an object includes obtaining an image data set from a raster scan. The image data set has a plurality of data points, each data point having an associated location and intensity; generating a reduced data set by selectively removing one or more data points from the image data set based upon an assigned probability of retaining the one or more data points in the data set, the assigned probability being a function of the intensity of a data point; generating a triangulation graph as a planar subdivision having faces that are triangles, the vertices of which are the data points and the edges of which are adjacent vertices; and segmenting the triangulated data set by finding a path with lowest cost between that vertex and every other vertex, wherein the cost is a function of the respective intensity of the vertices.

    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.
