CLaCS acronym stands for Cryo-Laser and Cryo-Sclerotherapy. It is a way to treat leg vein lesions by combining transdermal laser effect and injection sclerotherapy, all under skin cool in (Cyro - cold air blowed onto the skin at -20C). The laser causes a selective photothermolysis damage on the vein wall. The vein's lumen gets smaller. On a second procedure, sclerosing agent is injected where the vein is still open. The combination allows to treat veins that may need phlebectomy or foam sclerotherapy - more invasive options.

CLaCS can be done by Augmented Reality guidance. Augmented Reality in phlebology is achieved by using devices like VeinViewer and Accuvein. Both films the skin with an infra-red camera that is able to capture image of veins that are underneath the skin. This image is processed and projected back into the skin in a fraction of a second. The image that is seen is a green/red (VeinViewer/Accuvein respectively) image that shows the shape of the veins.
