14 EW SHOW DAILY Thursday Shanghai 2013 Hung-Won Tchah to give APACRS Lim Lecture by Erin L. Boyle EyeWorld Senior Staff Writer Hung-Won Tchah, MD H ung-Won Tchah, MD, Korea, has been chosen to give the 2013 APACRS Lim Lecture this year, and will focus on the topic "Modulation of Corneal Wound Healing after Surface Ablation." He will deliver the APACRS Lim Lecture following the Opening Ceremony on Friday, 12 July, which takes place from 08:30 – 10:00hrs in Hall 1, Level 4. About lecture In the lecture, Prof. Tchah will dis- cuss how corneal keratocytes have an important role in corneal wound healing as a result of corneal trauma. Keratocyctes become myofibroblasts and create collagens following trauma. Reasons for such corneal trauma can include corneal laser surgery. "Many researchers, including our group, have shown that surface laser ablation induces a more intense would healing response than LASIK, so there were more collagen deposits," Prof. Tchah said in material from the Asia-Pacific Association for Cataract and Refractive Surgeons (APACRS). "Keratocyte-induced wound healing is also one of the main factors for the regression of the effect after the LASIK procedure. Therefore, if we control the wound healing process—that is, mainly the keratocyte response—appropriately after corneal laser surgery, we can have better outcomes." About Prof. Tchah Prof. Tchah is Professor at the University of Ulsan Department of Ophthalmology, focusing on the fields of corneal, cataract, refractive, and laser surgery. "He has been at the forefront of ophthalmology's evolutionary changes throughout his career as a researcher, educator, lecturer and acclaimed physician and surgeon," according to the APACRS. Prof. Tchah graduated from the College of Medicine at the Seoul National University 1982 and completed his residency at Seoul National University Hospital, with fellowship training in anterior segment research at the University of Minnesota and affiliated hospitals. He returned to his hometown of Seoul in 1989 and began his professional career at the University of Ulsan, serving for 24 years as faculty in the Department of Ophthalmology. In 1991, he became a full professor. He has served as the Chairman of the Department of Ophthalmology and is currently Director of Cell Aging Research, Biomedical Research Center, Asan Medical Center, University of Ulsan. He was president from 20092011 and general secretary of the Korean Society of Cataract and Refractive Surgery. He was head of the Korean Corneal Disease Study Group from 2007 to 2009 and served on the Korean Ophthalmological Society as Director of Academic Affairs, Korean External Eye Disease Society, and Korean Contact Lens Society. Currently, Prof. Tchah is a member of the Board of Officers of the APACRS. "As a frequent lecturer throughout the world on cornea, cataract and refractive surgery, he has presented numerous speeches in medical conferences. He has published almost 200 peer reviewed journal articles. He is Regional Editor in Chief of the Korean editions and a member of the international advisory group of EyeWorld Asia-Pacific, the news magazine of the APACRS," according to the APACRS. He has also taken part in medical volunteer activity, beginning in his residency. He has been a medical volunteer in Laos, Cambodia, Nepal, and Vietnam. He is leader of the Medical Service Volunteer Group, Asan Medical Center, and Board member of Vision Care. EWAP Editors' note: Prof. Tchah has no financial interests related to this article. Gold Medal Award winner sees shifts in ophthalmology By Ellen Stodola, EyeWorld Staff Writer R onald Yeoh, MD, Singapore, is the recipient of this year's Gold Medal Award, an APACRS award that honors ophthalmologists who have contributed to the development of cataract and refractive surgery and ophthalmology in the Asia-Pacific region. Dr. Yeoh is a founding partner of Eye and Retina Surgeons Singapore and is also affiliated with the Singapore National Eye Centre and the National University Hospital, Singapore. Dr. Yeoh also is the secretary of the Asia-Pacific Association of Cataract and Refractive Surgeons (APACRS) and is on the program committee for the American Society of Cataract and Refractive Surgeons (ASCRS). He said receiving this year's award is a nice recognition. "It's always nice to be appreciated for the work we do," Dr. Yeoh said. "It is recognition for the work in education, training, research and setting clinical standards in the Asia-Pacific, which is made up of many countries Ronald Yeoh, MD from very different cultural and ethnic backgrounds." Dr. Yeoh said one of the things that he is most interested in is looking at new technologies for removing cataracts both safely and precisely that will especially help patients in the Asia-Pacific region. He said he also is particularly interested in advanced technology for lens implants that will improve refractive outcomes and visual performance. Dr. Yeoh said being sure to "tailor the technology to the appropriate location" is one key factor when looking at these techniques and technologies. One of the biggest challenges with his work in ophthalmology in the Asia-Pacific region, Dr. Yeoh said, is promoting a sense of togetherness and unity among the various cataract and refractive societies in Asia. "Understandably, most national societies have their own agendas," he said. "But the APACRS has sought to increase input and participation of these official societies so that they all feel a sense of ownership of the APACRS." At this year's APACRS meeting in Singapore, Dr. Yeoh said many of the Asian national societies helped organize various sessions for the meeting, which helps facilitate greater participation by some of these national societies. Dr. Yeoh said language and cultural barriers also come up as challenges with his work, as does resistance to change. "While there have always been challenges, the rewards are most fulfilling, and I have never begrudged these challenges," he said. "The APACRS is by far the smallest and the youngest of the major cataract and refractive societies," Dr. Yeoh said. "Yet, Asia has over 4 billion people, more than half the world's population." He said he thinks that APACRS can help get a grip on new important technological advances and spread them and information throughout Asia. "My hope is that one day, the APACRS, in collaboration with our partners in the ASCRS, ESCRS and LASCRS will create a world free of cataract blindness where our patients will benefit from the mutual learning we gain from these relationships," Dr. Yeoh said.
