Abstract
A combined sclerotherapy and light treatment method is described for the treatment of unwanted veins such as varicose and telangiectatic leg veins. Substantially increased success, in the range of 90-100%, has been achieved by implementing a dwell time of between 12 hours and 6 months between the light-based therapy and the sclerotherapy. Near infra-red wavelength light is preferably used in the light therapy due to its better depths of penetration through the skin to deeper lying, larger vessels such as varicose veins.
