ABSTRACT:
A method for reshaping the cornea comprises an initial step of determining the precise volume of corneal tissue which must be removed in order to attain the desired vision correction. A pulses laser beam, having a pulse energy density sufficient to cause photoablation of corneal tissue near the threshold of the plasma regime, is directed onto the eye for removal of relatively large portions of tissue from the precisely determined volume to establish a corrected surface. A pulsed laser beam, having a pulse energy density sufficient to cause photoablation of corneal tissue substantially below the threshold of the plasma regime, is then directed onto the corrected surface to take away relatively small portions of corneal tissue and thereby smooth the corrected surface.
