Abstract
A method for modifying tissue with a quasi-continuous laser beam to change the optical properties of the eye comprises controllably setting the volumetric power density of the beam and selecting a desired wavelength for the beam. Tissue modification is accomplished by focusing the beam at a preselected start point in the tissue and moving the beam's focal point in a predetermined manner relative to the start point throughout a specified volume of the tissue or along a specified path in the tissue. Depending on the selected volumetric power density, the tissue on which the focal point is incident can be modified either by photoablation or by a change in the tissue's visco-elastic properties.
