CLaCS

CLaCS is a treatment for leg vein lesions by combining transdermal laser effect and injection sclerotherapy, all under skin cooling. The laser causes a selective photothermolysis damaging the vein wall. The vein's lumen gets smaller. On a second procedure, sclerosing agent is injected where the vein is still open. This combination can be used treat veins that could be treated by phleboectomy or foam sclerotherapy - more invasive options. To improve results, CLaCS can be guided by Augmented Reality.
CLaCS was created by Dr. Roberto Kasuo Miyake, in 1999, to adhere to patients' requests for treatment that did not require hospitalizations.
