Overview
1 / 12
Eyereum Eye Clinic (아이리움안과) is a leading research-oriented ophthalmology center located in Gangnam, Seoul. Founded by Dr. David Sung-Yong Kang in 2011, the clinic has established itself as a global authority in vision correction surgery, particularly SMILE LASIK and ICL lens implantation.
Our Core Values
100,000+ Eye Surgeries
Dr. Kang Sung-yong has performed over 100,000 vision correction procedures, placing him among the most experienced refractive surgeons globally. This extraordinary volume provides a foundation of pattern recognition and technical precision that newer surgeons simply cannot replicate.
65+ SCI Publications
With over 65 papers published in SCI-indexed international journals, EYEREUM's clinical practice is backed by rigorous scientific research. This academic output demonstrates that the clinic's techniques are not just effective in practice — they're validated by the global scientific community.
Zeiss SMILE International Ambassador
Dr. Kang's appointment as a Zeiss SMILE Ambassador and ISRS International Council member (2020-2023) reflects his standing as a global authority in minimally invasive vision correction. This international recognition means patients are treated by a surgeon who helps set industry standards.
10-Year ICL Clinical Data
EYEREUM has accumulated a decade of long-term follow-up data on EVO+ Aqua ICL lens implantation — one of the most comprehensive longitudinal datasets available. This evidence gives patients confidence that their vision correction results will remain stable for years.
Underground Direct Access from Gangnam Station
Connected to Gangnam Station Exit 2 via an underground passage, EYEREUM is reachable regardless of weather conditions. This all-weather accessibility is especially valuable for post-operative patients who need to protect their eyes from sun and wind.
World-Class Research Credentials
The clinic has published over 65 SCI-indexed research papers, demonstrating their commitment to evidence-based medicine. Dr. Kang and his team have received the prestigious ASCRS (American Society of Cataract and Refractive Surgery) SMILE Best Paper Award in both 2018 and 2024, recognizing their contributions to advancing vision correction technology.
