The pulsed diode laser utilized in this study provides a safe and effective treatment that achieves reduction of unwanted leg vein telangiectasias. Patients with blue or purple leg veins between 0.4 mm and 1 mm in diameter can be effectively treated with an 800 nm diode laser.Clinical research shows that the optimal treatment parameter for these size vessels is a

fluence of 40 J/cm2 at a 30 ms pulse width.
