Dr. Kim Byoung Joon – Varicose Vein Specialist in Busan, Korea

Who is Dr. Kim Byoung Joon?

Dr. Kim Byoung Joon is the director and founder of the Kim Byoung Joon LEDAS Varicose Vein Clinic in Seomyeon, Busan. He is a board-trained thoracic and cardiovascular surgeon — a vascular-trained surgeon, not a cosmetic doctor — who chose in 2001 to dedicate his practice to diseases of the leg veins. Every patient at LEDAS is examined and treated under his direction.

Thoracic and cardiovascular surgeons make up a small share of Korea's medical specialists. Their training covers the heart, lungs and blood vessels, which is why many Korean vein specialists come from this field. If you are wondering what kind of doctor treats varicose veins , this background is one of the most relevant you can look for.

What training and qualifications does he have?

All of Dr. Kim's medical education took place at Pusan National University, one of Korea's leading national universities:

• Doctor of Medicine (medical school)
• Internship and residency in thoracic and cardiovascular surgery
• Master of Science, School of Medicine
• Ph.D. candidate, School of Medicine

He later served as an adjunct professor at the same medical school, teaching the next generation of doctors.

Professional societies

Dr. Kim is a founding member of the Korean Society for Phlebology, the Korean professional body dedicated to vein disease. He is also a lifetime member of the Korean Society for Thoracic & Cardiovascular Surgery and director of its Busan·Ulsan·Gyeongnam branch. Membership in these societies keeps him close to current national practice and guidelines.

How much experience does he have with varicose veins?

Dr. Kim has treated varicose veins for over 22 years. LEDAS passed the milestone of 20,000 varicose vein procedures in 2022, and by 2026 the clinic counters showed 29,847 patients treated and 47,831 patient visits. Patients have come from 37 countries.

Volume matters in vein care because the most important step — reading the ultrasound and finding every leaking vein — is a skill that improves with repetition. Dr. Kim personally developed the three-step LEDAS treatment system from this experience.

What is his approach to treatment?

Dr. Kim believes that most recurrences come from three avoidable problems: an incomplete diagnosis, the wrong treatment plan or method, and a lack of follow-up. His approach targets each one.

1. Diagnose completely. Every leg is mapped with high-end duplex ultrasound before any decision is made. See our duplex ultrasound exam .
2. Treat the cause, then the branches. Large refluxing trunk veins are closed with EVLT using a 1940nm laser. Hidden and smaller veins are treated with duplex-guided sclerotherapy and sclerotherapy.
3. Follow up for life. Patients are invited for an ultrasound check every 1–2 years, or whenever overseas patients return to Korea, through the relapse prevention program .

All procedures are done under local anesthesia, with no incision and same-day discharge. Dr. Kim moved away from traditional stripping surgery because it requires general or spinal anesthesia and longer recovery.

What patients can expect from him

Dr. Kim explains the ultrasound image on screen as he scans, so you can see the leaking vein yourself. He will tell you plainly if treatment is not needed yet, or if a conservative option such as compression stockings is more suitable for now.

Does he teach other doctors?

Yes. Beyond his former university post, Dr. Kim leads the LEDAS Academy , which trains physicians in EVLT, ultrasound-guided foam sclerotherapy, sclerotherapy, vein ultrasound and long-term follow-up through theory, clinical observation and case-based learning.

What recognition has he received?

Dr. Kim is listed in Marquis Who's Who (2018) and was selected as a “Good Doctor” of the Republic of Korea by MediTimes. Under his leadership LEDAS received the Prime Minister's Citation for Global Healthcare (2023), the Grand Prize at the Busan Medical Industry Awards, and Korea's first ESQR Quality Choice Prize (2025). He also serves as Senior Vice President of the Seomyeon Medical Street Council and sits on the Busan Medical Tourism Promotion Committee. Full details are on our awards page .

How can I consult Dr. Kim from abroad?

You can send your symptoms and any previous scans through our online consultation form, or visit one of the 12 remote consultation centers in 7 countries. A final treatment plan is always made after Dr. Kim scans your legs in person in Busan.
