Photoderm, Laser
Intense pulses of light (photoderm, lasers) are also used in treatment of small varicose veins. Light energy of 20-50 joules is transmitted for 0.003 seconds [NOTE: or convert this to "3 milliseconds"?]. Powerful photon particles pass through relatively light-colored skin, are absorbed by darker-colored vessels, and are converted to heat. High temperatures of 190-200 F are achieved for 1-2 milliseconds in these darker colored unwanted veins and cause degeneration in the vein walls. Treated veins are eliminated by resorptions (similar to sclerotherapy) over a period of 2-12 weeks.
Therapy usually takes 30-40 minutes, and patients may resume their normal activities right after the sessions.
