METHOD OF CORRECTING HIGHER-ORDER ABERRATIONS USING LASER VISION CORRECTION

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)=t.sub.0+.DELTA.t(X,Y)/(n-1), where .DELTA.t(X,Y) represents a higher-order wavefront elevation and to represents the thickness of the lenslet having a spherical refractive power of D.
