Cryo Laser and Cryo Sclerotherapy, also known as CLaCS, is a treatment for spider veins and small varicose veins (telangiectasias and reticular veins), pioneered by Prof. Kasuo Miyake, São Paulo, Brazil, in 1999. The technique combines transdermal laser and sclerotherapy to improve cosmetic appearance and provide sustained treatment benefits. CLaCS is now available in more than 30 countries around the globe and is considered a treatment option for challenging cases of C1 venous disease. CLaCS was introduced at Surekha Varicose Veins Clinic in 2019, and over the years, it has been used to treat hundreds of patients. Dr. Ashish Dhadas has shared his knowledge and experience in CLaCS with 50% Dextrose on national and international forums. We also offer training in this treatment technique to interested Phlebologists.**
