    摘要： A computer-implemented method for assessing at least one optical property of kth order, k=2, 3, 4, . . . of an optical element at at least one evaluation point, wherein the optical element comprises at least one boundary surface formed of a refractive base surface and at least one phase-modifying optical element, the method comprising: determining the properties of a wavefront in the local surrounding of the at least one evaluation point by means of a local wavefront tracing; and determining the at least one optical property at the at least one evaluation point on the basis of the properties of the wavefront in the local surrounding of the at least one evaluation point, wherein the local wavefront tracing comprises a local wavefront tracing upon passage through the at least one boundary surface, and the local wavefront tracing upon passage through the at least one boundary surface is performed according to the equation for the local wavefront tracing through the refractive base surface, the equation being supplemented by an additive additional term PK(k).
