Varicose veins is a condition where the one-way valves in the veins do not function properly, causing backflow of the blood into the legs where it collects. When the blood collects, the affected veins start to bulge or become twisted, and usually turn a darker blue or purple. They may cause pain and difficulty in moving around for some people, and for most they will find it a cosmetic concern. People are more likely to get varicose veins if they do not move from a standing or sitting position for a prolonged period of time (sitting at a desk the whole day etc). Varicose veins will get progressively worse if left untreated, and more extensive surgery may be required during later stages. If you suspect you have varicose veins, do consult a doctor earlier to initiate treatment before the disease worsens.

Founded in 2002, CLaCS is a relatively new treatment for varicose and spider veins. It involves using laser therapy to burn and damage the walls of the varicose veins, then injecting a substance (sclerosant) which shrinks the veins. Throughout the procedure, cold air is blown onto the skin to numb it so no pain should be felt by the patient. There are little to no surgical scars as the laser only damages the inner walls of the vein and does not mar the skin. CLaCS Singapore is more effective on veins which are shallower (closer to the skin) – for deeper veins, other treatments such as endovenous heat ablation are more suitable. You may want to consult a doctor or specialist to discuss which treatment method is best for your condition.

Here are some things to take note of regarding the procedure:

Before surgery

Patients undergoing CLaCS Singapore treatment should refrain from applying any artificial skin-tanning agents on their skin (regardless which area). This is because it could interfere with the visibility of the infra-ray scan of the spider veins projected onto the skin.

If your doctor has assessed that you have sensitive skin and might still feel discomfort even with cold air blown onto your skin, they may apply numbing cream onto the targeted areas.

After Surgery

After the procedure, positive results should begin to show after 2-3 weeks. The varicose or spider veins may take 1-2 months to disappear completely – while the veins may still appear darker during the first two weeks after the surgery, they are in the process of healing so there is no need to worry. There should be no need for further therapy such as compression stockings after surgery, and you will be able to return to work and your daily lifestyle as per normal 4-6 hours after. Exercise can be resumed 24 hours (1 day) after the surgery.

It should be noted that though the treated veins are likely to never be problematic again, new spider and varicose veins can always develop in other untreated areas. This is why it is important to change your lifestyle, such as exercising more often and wearing compression stockings if you have to sit or stand for long periods.
