What is CLaCS?

 CLaCS (Cryo Laser & CryoSclerotherapy) is a safe, fast, and effective treatment for varicose veins and spider veins. It combines:

  • Laser therapy to shrink veins

  • Injection therapy (sclerotherapy) to close veins

  • Vein imaging (VeinViewer) to see even tiny feeder veins

  • Extreme skin cooling for comfort (-20°C)

Swift Day Surgery Center is the only clinic in the UAE and one of the few in the Middle East offering this advanced treatment.

Why CLaCS is Special

  • Treats veins precisely and safely
  • Painless and very comfortable due to cooling
  • Long-lasting results
  • Can treat both legs and body veins
  •  walk and return to normal activities immediately
  • Some veins disappear right after treatment

Who is the Ideal Candidate for CLaCS?


CLaCS is perfect for people looking to improve the appearance and comfort of spider veins or varicose veins with a safe and effective solution. Our doctor evaluates:

  • The overall condition of your veins
  • Function of deep veins and venous valves
  • Any previous treatments or interventions

After a thorough evaluation, a personalized treatment plan is created to ensure the best long-term results.

Why Isn’t CLaCS Treatment Widely Available in the Middle East?

 CLaCS is an advanced and specialized treatment that requires:

  • High-end technology like VeinViewer and cryotherapy units
  • Skilled doctors trained specifically in CLaCS technique
  • Careful patient evaluation and precise procedure execution

Because of these requirements, few clinics in the Middle East offer CLaCS, making it an exclusive and highly specialized solution.

Most sessions take 30–45 minutes, and you can walk right after.
