Abstract
Improved methods of spherical and astigmatic laser correction. By using an array of micro-charge coupled devices, a spatially-resolved refractive error map is generated which guides the treatment process. Improved astigmatic correction is provided by avoiding laser treatment of the unaffected cornea. Complex astigmatic corrections including lenticular astigmatism and mixed astigmatism are treated by first sphericizing the corneal surface before correcting the residual refractive error.
