Publication number: 20210401624Abstract: 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.Type: ApplicationFiled: June 24, 2021Publication date: December 30, 2021Inventors: Zsolt Bor, Imre Hegedus, Keith Watanabe, Alireza Malek Tabrizi

Publication number: 20210369500Abstract: 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+?t(X,Y)/(n?1), where ?t(X,Y) represents a higher-order wavefront elevation and to represents the thickness of the lenslet having a spherical refractive power of D.Type: ApplicationFiled: May 26, 2021Publication date: December 2, 2021Inventors: Imre Hegedus, Zsolt Bor
