Abstract
A conventional keratomileusis procedure is modified to the extent that a controlled tissue-ablating laser radiation is applied solely to the freshly cut part of the cornea that is left after severing the lenticle, the radiation being so controlled and characterized as to effect a volumetric removal of exclusively stromal tissue that, upon replacement of the lenticle over the thus-sculptured remainder of the cornea, a new and optically corrected curvature results.
