Abstract
The invention relates to an apparatus for performing a treatment on tissue. The apparatus can feature a hand piece having a waveguide with an output for applying radiation from an optical radiation source to the tissue. In addition, the apparatus can include a reflective mask coupled to the output of the waveguide. The reflective mask can have a spatial pattern with openings therein to provide selected treatment spots on the tissue.
