  • Laser surgery method
    Patent number: 5403306
    Abstract: A laser surgery method is disclosed for use in efficient ablation of tissue with little or no thermal damage to adjacent tissues. The wavelength of the surgical laser is tuned to an absorption peak of a proteinaceous material or functional groups contained therein, the amides for example. A suitable power level is chosen to either vaporize or liquify the targeted tissue.
