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 ...
A method for controlled reshaping of the cornea of the eye which comprises the steps of: removing a specified volume of corneal tissue by photoablation using laser pulses having plasma forming energy densities to establish a predetermined corrected surface; and smoothing said corrected surface by photoablation using laser pulses having energy densities substantially below an effective plasma forming level.
