Abstract: A fiducial is generated on an internal anatomical structure of the eye of a patient with a surgical laser. A toric artificial intraocular lens (IOL) is positioned so that a marker of the toric IOL is in a predetermined positional relationship relative to the fiducial. This positioning aligns the toric IOL with the astigmatic or other axis of the eye. The toric IOL is then implanted in the eye of the patient with high accuracy.

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: In a laser cataract procedure that also corrects for astigmatism, an iris registration method compares an iris image of a patient's eye taken when the eye is not docked to a patient interface device with an iris image of the same eye that is docked to the patient interface, to calculate a rotation angle between the two images. The astigmatism axis of the eye is measured when the eye is not docked, and the measured axis is rotated by the calculated rotation angle to obtain a rotated astigmatism axis relative to the iris image of the docked eye. The laser cataract procedure is performed based on the rotated astigmatism axis. The rotation angle is calculated by optimizing a transformation that transforms the undocked iris image to match the docked iris image, where the transformation includes a dilation factor that accounts for different pupil dilation of the two iris images.

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 systems for planning and forming incisions in a cornea, lens capsule, and/or crystalline lens nucleus are disclosed. A method includes measuring spatial dispositions, relative to a laser surgery system, of at least portions of the corneal anterior and posterior surfaces. A spatial disposition of an incision of the cornea is generated based at least in part on the measured corneal anterior and posterior spatial dispositions and at least one corneal incision parameter. A composite image is displayed that includes an image representative of the measured corneal anterior and posterior surfaces and an image representing the corneal incision.

Abstract: In a cataract procedure, a new geometry of a lens segmentation pattern reduces the required phacoemulsification energy to remove the lens. The lens segmentation process employs a three-dimensional spiral lens segmentation pattern that resembles a spiral staircase or a spiral ramp, to incise a vertical cylindrical volume of the lens into a three-dimensional spiral that can be more easily removed. The segmentation patter is formed by scanning the laser focal spot in a layer by layer manner, each layer including a closed curve corresponding to the outer boundary of the segmentation volume, and a filled area inside the closed curve forming a horizontal step of the spiral staircase. The horizontal steps of vertically adjacent layers are offset by an offset angle, creating the spiral lens segmentation pattern that form a spiral volume.
