Abstract:
1. A method for treating a layer of tissue, comprising: selecting a layer of tissue to be targeted, said targeted layer having an overlying layer; choosing a laser beam of defined characteristics, wherein said defined characteristics of said laser beam comprise laser pulses within the range of a femtosecond to picoseconds, said laser pulses producing multiphoton laser tissue effects, said laser tissue effects including laser tissue alteration via multiphoton absorption, whereby at every point other than at the targeted layer said laser beam has sufficiently lower fluence than the fluence at the targeted layer; and applying said laser beam to the targeted layer, such that the targeted layer is selectively affected by said effects of said laser beam, wherein collateral damage to tissue surrounding the targeted layer is below a preselected threshold.
