摘要
A method for treating a condition in a tissue, includes the steps: (1) providing a PS within the tissue; (2) irradiating the tissue containing the PS with a first light of a first wavelength; and (3) irradiating the tissue containing the PS with a second light of a second wavelength so as to treat the condition in the tissue, wherein: (a) the PS absorbs light at the first wavelength and the second wavelength; and (b) the second light is more strongly absorbed by the tissue than the first light or vice versa, so as to achieve a predetermined absorbed photon density gradient. An apparatus for conducting the method includes first and second light sources, a power supply, a focusing device, and a controller which adjusts light emission such that I(d)=I(λ1 at d=0)×exp (μeff (λ1)×d)+I(λ2 at d=0)×exp (μeff(λ2)χd).
