Patent ID: 8182472

Claim:
A method for customized correction of an eye, the method comprising: measuring a regular refractive error and an irregular refractive error of the eye, the regular refractive error comprising a spherical error and a cylindrical error, the cylindrical error having a cylindrical power and an astigmatism axis; selecting a tissue-shaping body in response to the regular refractive error of the eye from among a set of alternative tissue-shaping bodies having differing associated spherical and cylindrical powers, the selected tissue-shaping body having a selected tissue-shaping surface, a spherical power substantially corresponding to the spherical error of the eye, and a cylindrical power substantially corresponding to the cylindrical error of the eye; aligning a cylindrical axis of the selected tissue-shaping body with the astigmatism axis of the eye; engaging the selected tissue-shaping surface against the eye so as to conform an eye surface to the selected tissue-shaping surface; determining a three-dimensional target laser surface in response to the irregular refractive error of the eye; and incising tissue of the eye by scanning a laser spot in three dimensions through the tissue along the laser target surface so as mitigate the regular refractive error and the irregular refractive error of the eye.
