Dr. Kazuaki Kadonosono, M.D., Ph.D.

Dr.Kadonosono graduated from Yokohama City University School of Medicine, Japan. He completed his residency in Ophthalmology at the Yokohama City University Hospital. And then served on the faculty as the director of retina department at Yokohama City University, School of Medicine. His research interests include the development and evaluation of new surgical techniques in vitreoretinal and macular surgery. He has participated in numerous studies of novel treatments in the retinal diseases. He has been on the Board of Japanese Ophthalmological Society (JOS), the Executive director of Japanese Retina and Vitreous Society (JRVS), and belongs to American Society of Retina Specialist (ASRS), American Academy of Ophthalmology (AAO) and Macula Society. Currently, he serves as Professor and Chair of Department of Ophthalmology and Micro-technology, Yokohama City University.

Prof. Kyoko Ohno-Matsui

Kyoko Ohno-Matsui is Professor and Chair of the Department of Ophthalmology and Visual Science at Tokyo Medical and Dental University (TMDU). She is also the Chief of the High Myopia Clinic of TMDU. She graduated from Yokohama City University Medical School and received her Ph.D. at Tokyo Medical and Dental University. She did postdoctoral fellowship at Wilmer Eye Institute at Johns Hopkins University.

Her research mainly focuses myopia, especially pathologic myopia. The High Myopia Clinic at TMDU was established in 1974, and now registered patients have exceeded 6,000 from all over Japan and from abroad. Based on the long-term progression study, she established international photographic classification of myopic maculopathy. She is especially interested in how eye is deformed in pathologic myopia, and then how eye deformity damages retina and optic nerve. As a method to visualize the shape of the entire globe, she established a new technique called '3D MRI of the eye'. Based on 3D MRI and wide-field fundus imaging, she proposed a novel classification of posterior staphyloma. Using various imaging modalities (especially swept-source OCT), she has been detecting structural abnormalities which occur in various tissues in eyes with pathologic myopia. Currently she is actively working on ultra-wide field OCT imaging to visualize the entire extent of staphyloma in many patients in vivo. Her lab also investigates basic mechanism of myopization and ocular angiogenesis.

Dr. Ohno-Matsui has been the recipient of Young Investigator Award in Japanese Ophthalmological Society and the Excellence in Research Award at TMDU. She has authored or co-authored over 238 manuscripts which were published in prestigious journals. She is the active member of Macular Society, Retina Society, and Club Jules Gonin.

Prof. Christopher Liu

Born in Hong Kong to a medical family, Christopher studied for O and A levels in England and went on to train at the Charing Cross Hospital, University of London, graduating with BScHons and obtaining his MBBS qualification in 1985. Christopher then specialized in ophthalmology, training at Charing Cross, Western Ophthalmic, and Moorfields Eye Hospitals. He completed higher ophthalmic surgical training at Addenbrooke's Hospital in Cambridge and West Norwich Hospital and is a Fellow of the Royal College of Ophthalmologists.

Professor Liu is renowned for his interest in OOKP (osteo-odonto-keratoprosthesis) surgery, a revolutionary form of artificial corneal implant for patients with end-stage corneal blindness. OOKP was originally being practised only in Italy by Professor Giancarlo Falcinelli. Christopher learnt Italian and then spent frequent periods in Rome between '93 and '96 studying the technique which uses one of the patient's own teeth to create the corneal implant. Christopher's work came to the nation's attention in 2004 with UK media coverage of a very successful OOKP operation on a 42 year old woman from Teeside. Judith Smith, who had been blind for 15 years prior to the surgery, was overwhelmed with joy at seeing her grandchildren's faces for the very first time. (Link to

Christopher has established a centre of excellence for OOKP surgery at The Sussex Eye Hospital in Brighton, serving the UK and beyond, where he leads a multi-disciplinary team for which he has secured central government funding. He has travelled widely to raise awareness of and teach OOKP surgery, with Visiting Professorships across the globe: Kinki University Medical School in Osaka, Japan and the All India Institute of Medical Sciences in Delhi, India. He has received the Spanish 'Member of Merit' award from the Barraquer Institute in Barcelona and is a visiting Senior Consultant to the Singapore National Eye Centre.

Professor Liu has a national and international profile for cataract surgery, having taken on particularly challenging cases such as patients with small pupil cataracts, iris defects and loose zonules with excellent clinical outcomes. He has published research into risk stratification for safe cataract surgery and has pioneered safe techniques for operating on cataracts in both eyes in one theatre slot, minimizing risk of infection.

An experienced laser and lens refractive surgeon, Professor Liu uses both LASIK and surface treatment procedures (such as PRK). He was President of the British Society for Refractive Surgery (BSRS) from 2005 to 2008 and was President of the Medical Contact Lens & Ocular Surface Association from 1998 to 2000. He also specializes in the treatment of corneal and external eye disease and in looking after patients with glaucoma.

Widely published, with over 200 academic papers, Christopher has been the Research Lead in Ophthalmology at Brighton & Sussex University Hospitals NHS Trust and is Honorary Clinical Professor at Brighton & Sussex Medical School.
