Celebrating Singaporean - Professor Donald Tan Tiang Hwee

Professor Donald Tan Tiang Hwee In the company of Singapore's finest eye surgeons. That was the privilege I had yesterday when I attended a public awareness talk on cornea donation organised by the Lion's Club of Singapore. And the luminaries that graced the occasion, other than the senior Lions, were Professor Arthur Lim himself and Professor Donald Tan. A/Professor Heng Yim Jin and Dr Lim Li also made their presentation in the public seminar. Professor Arthur Lim has been an authority in eye surgery for many years and is probably the father of this field of medical science, and a mentor to the many fine eye surgeons we have here. It is heartening to know that he has a worthy successor to continue his great works and to make more progress and discoveries in this field. Together, they have made the Singapore National Eye Centre a top class eye clinic and famous around the world. They not only have a superb track record to their credits, including the highest success rate in cornea transplant, lowest tissue rejection rate, lowest cell loss rate, they are also constantly doing R and D to develop new methods and technology in cornea transplant. They improved on the technology and techniques being used, they also developed new techniques that are new frontier science and technology. Such achievements and track records need to be made known to all, especially Singaporeans that we are truly among the best. I have attached a press release by SNEC below to give more details of their achievements, including the technical jargons of cornea transplant and other surgical treatments by other equally great eye surgeons in the Centre. This press release is dated Sep 04 which is not too current, but good enough to so how much they had done since then. SNEC 15TH ANNIVERSARY INTERNATIONAL MEETING The Singapore National Eye Centre will mark another milestone as we celebrate our 15th Anniversary since inception in 1990 with a year-long programme beginning with the SNEC 15th Anniversary International Meeting which will be held from 3 to 6 September 2004. The Theme of the Meeting: Clear Vision for All Ages, represents the mission of every ophthalmologist. There will be a high quality scientific programme featuring symposia, updates, masterclasses, skill transfer courses and live surgery demonstration presented largely by our local ophthalmologists. Renowned ophthalmologists from all over the world are also invited to speak in this Meeting. SNEC will be uncovering some of our new and significant advances from our major subspecialties that will impact the practice of ophthalmology. New Advances in Lamellar Keratoplasty Assoc Prof Donald Tan Associate Professor Donald Tan is the Deputy Director of the SNEC and Senior Consultant and Head of Cornea and External Eye Disease Service. He is also Director of the Singapore Eye Research Institute and holds dual appointment as associate professor at the Department of Ophthalmology, National University of Singapore. A/Prof Donald Tan spearheaded the cornea development with the introduction of new techniques of ocular surface transplantation and amniotic membrane transplantation in Singapore since 1997. The SNEC is now the leading Centre in these techniques in Asia besides Japan. In collaboration with dental surgeons from the National Denetal Centre, A/Prof Donald Tan led eye surgeons in SNEC to successfully complete the revolutionary two-stage Osteo-Odonto Keratoprosthesis Surgery to enable a blind boy from Thailand to see. This is the first operations of its kind in South-East Asia. Lamellar Keratoplasty (LK) refers to a surgical procedure in which the anterior corneal layers, to a variable stromal layer depth are replaced with donor tissue. The lamellar keratoplasty is used for the management of various corneal disorders and it is fast re-emerging as a viable option for corneal replacement surgery. SNEC has achieved new and significant advances in the area of LK and recent innovative surgical techniques and tolls are now emerging which allow corneal surgeons to perform LK with excellent visual results. LK has distinctive advantages over penetrating keratoplasty: sutures can be removed earlier, risks for wound dehiscence and graft failure due to allograft rejection are reduced. The need for therapeutic lamellar surgery has become more pressing in Asia, where tectonic and therapeutic indications for keratoplasty remain major indications, and the ability of corneal surgeons to perform “match and patch” grafts of various sizes and shapes allows for treatment of complex disorders such as tectonic lamellar surgery in Mooren’s ulceration and scleral melting after adjunctive pterygium surgery. At the SNEC, a review of indications for lamellar surgery show that 40% of LKs are performed for tectonic indications, while a third are performed for optical reasons, and a quarter for therapeutic indications. Clinical Applications of Optical Coherent Tomography Dr Doric Wong Dr Doric Wong is a senior consultant ophthalmologist with the Vitreo-Retina Department and the Cataract and Comprehensive Department of the Singapore National Eye Centre. He also practises in the Department of Ophthalmology of the Changi General Hospital. Dr Doric Wong spent a year at the Manhattan Eye, Ear and Throat Hospital, New York, where his focus was on medical retina. His practice encompasses most aspects of surgical retina, specifically retinal detachments, and PVR, diabetic retinopathy, macular surgery and trauma. In medical retina, his interest is on choroidal neovascular disease and polypoidal choroidal vasculopathy. Dr Doric Wong has been invited to lecture and to teach extensively in the region. A high-powered resolution imaging for retina, the Optical Coherence Tomography (OCT), is now available at the Singapore National Eye Centre. OCT has matured as an investigative tool in ophthalmology over the last few years. It now provides a new and reliable and reproducible way of visualisng diseases of the retina, providing information otherwise not visible through other means. A highly detailed cross-section view of the retina can be recorded using infra-red light and special acquisition techniques. An image akin to one using a microscope to examine a slice of the retina is obtained from a patient’s eye without being invasive. Subtle changes of the retina, and its relationships with structures above and below it can be visualized and documented, helping doctors to understand disease processes which affect the retina and monitor changes with treatment. Femtosecond Laser Technology: Current Status and Future Perspectives The Femtosecond Laser Technology is fundamentally a new technology utilizing the fine precision of a femtosecond laser as a surgical tool and has applications in a host of eye surgeries including its ability to laser as a corneal flap for LASIK surgery to correct myopia, perform corneal transplantation with precise accuracy and also perform glaucoma surgery. The femtosecond laser system has the ability to perform accurate but gentle surgery on the cornea without fist having to apply heavy suction forces and deforming the natural shape of the cornea. The potential of this technology lies in the co-development of new corneal transplantation procedures which may result in improved safety and visual outcomes in patients blind from corneal diseases.
