Abstract: Systems and methods for intraocular lens selection include receiving, by one or more computing devices implementing a prediction engine, pre-operative multi-dimensional images of an eye; extracting, by the prediction engine, pre-operative measurements of the eye based on the pre-operative images; estimating, by the prediction engine using a prediction model based on a machine learning strategy, a post-operative position of an intraocular lens based on the extracted pre-operative measurements; selecting a power of the intraocular lens based on the estimated post-operative position of the intraocular lens; and selecting the intraocular lens based on the selected power. In some embodiments, the systems and methods further include receiving post-operative multi-dimensional images of the eye after implantation of the selected intraocular lens, extracting post-operative measurements of the eye, and updating the prediction model based on the pre-operative measurements and the post-operative measurements.

Abstract: The disclosure provides a method for correcting higher-order aberrations including providing a laser radiation. The method also includes controlling a location of a beam focal point of the laser radiation by a system of scanners and guiding the beam focal point in such a way that the location of the beam focal point is in a cornea of an eye. The method further includes introducing the laser radiation into the cornea of the eye. The method includes cutting a lenslet, wherein a thickness of the lenslet t(X,Y) satisfies a following equation: t(X,Y)=t0+Δt(X,Y)/(n−1), where Δt(X,Y) represents a higher-order wavefront elevation and t0 represents the thickness of the lenslet having a spherical refractive power of D.

Abstract: A laser surgical system comprises a laser source, scanners, delivery optics, and a computer. The laser source generates a beam of femtosecond laser pulses. The scanners direct focus spots of the beam towards points of a cornea. The delivery optics focuses the focus spots at the points of the cornea. The computer creates an incision in the cornea by instructing the optics and scanners to: direct and focus the focus spots from a posterior corneal surface, through a convex curve and a concave curve, to an anterior corneal surface to form an S-curve incision with a posterior end and an anterior end. The S-curve incision has a substantially non-planar rectangular shape with a longer side that extends from the posterior end to the anterior end and defines a longer direction. A cross-section of the incision in the longer direction exhibits the convex curve and the concave curve.
