Devices, systems, and methods for laser eye surgery selectively ablate tissues withinthe cornea of an eye along one or more target surfaces, so that corneal tissue borderedby the laser incision surface(s) can be mechanically removed. An appropriate tissue-shapingsurface can be selected based on the regular refractive error of the eye, and ashape of the target laser surface(s) can be calculated so as to correct irregularrefractive errors of the eye, impose desired additional sphero-cylindrical and/orirregular alterations.
