Clinical Application:
Spider vein treatment with VELAS30A diode laser from GIGAALASER

Clinic Explanation:
Spider vein, are very small reddish blue venules located in the skin which have enlarged and become visible. Traditional surgery methods are invasive and may not achieve good performance for some fine caliber vessels.
Laser therapy is ideal for spider veins. And the 810nm diode lasers are considered the most efficient light sources available and are particularly well suited for clinical applications. It works by delivering pulses of light energy which cause the blood within the vein to coagulate, eventually destroying the vessel which is later reabsorbed by your body. Then the enlarged capillary vessel will disappear and spider veins will be effectively removed.

Medical device:
VELAS30W 810nm
Operation power: 15-18W
Mode: Pulse, T-on: 40-70ms, T-off: 400-600ms

Accessories:
Focus handpiece, cooling gel

Operation procedure:
1. If hair is present, please shave the treatment area immediately before beginning the laser treatment. As the hair will absorb the laser energy and burn, causing discomfort.
2. It is not necessary to use anesthesia. Sensitive patients can use EMLA
3. Connect the handpiece with device, turn on the device and setting parameters. (PS: The suggested energy density is about 300-500J/cm2)
4. Wearing laser safety goggle, gently touch the skin with focus handpiece but not to apply pressure. Treading the footswitch, the laser irradiates the vascular lesion. Irradiating with low energy at first and observing the reaction of the lesion. The best treatment result is there are have white spots occurs in local tissue and the vessel shrinked.
5. After the treatment, coating the cooling gel for 20 minutes to decrease thermal damage.

Advantage:
1. Non-invasive procedure, no scar
2. Easy and safe operation. At 810nm wavelength there is less energy absorbed by the competing chromophore (melanin) than when shorter wavelengths are used. This can reduce side effects caused by interaction with the melanin in the epidermis.
3. More effectively. 810nm wavelength penetrates deeper into the skin than most other systems and thus may be more effective at reaching the target area.
4. No blood and pain

Notice:
L Vessels between 0.4 mm and 1 mm in diameter have been shown to respond best to
810nm laser treatment
L It is necessary to adjust the spot size, pulse duration and energy density according to patients' age, gender, skin color and lesion during the operation.
L Three times treatments are recommended for best results. And it would be better that each treatment have 4 weeks interval
L Patients should avoid sun exposure for six weeks before treatment
L Patients with tans are not suggested to do the treatment
