Laser energy is transmitted through the optic fiber to a lens at one end which is adapted to focus the laser energy through the hollow needle and into a blood vessel, for creating a blood clot, or into the tissue immediately adjacent a damaged blood vessel for creating white scar tissue thereby causing the vessel to shrink in size and at least partially disappear from view.Other References
