Geoffrey Craig Tabin, MD
Fairweather Foundation Professor
BioDr. Geoff Tabin is Co-Founder and Chairman of the Himalayan Cataract Project and a Professor of Ophthalmology and Global Medicine at Stanford University. He has published more than 45 peer-reviewed articles, two books and a dozen book chapters related to his work in ophthalmology and the developing world.
Dr. Tabin is the fourth person in the world to reach the tallest peak on each of the seven continents. His passion for mountain climbing directed him to his professional career in eye care. After summiting Mt. Everest, on one of his expeditions, he came across a Dutch team performing cataract surgery on a woman who had been needlessly blind for three years. It was then he understood his life calling.
Tabin graduated from Yale University and then earned an MA in Philosophy at Oxford University on a Marshall Scholarship. From there, he took his interest in moral philosophy and health care delivery to Harvard Medical School where he earned his MD in 1985. After completing an ophthalmology residency at Brown University and a fellowship in corneal surgery in Melbourne, Australia, Dr. Tabin returned to Nepal to work with Dr. Sanduk Ruit.
Tabin and Nepalese eye surgeon Dr. Sanduk Ruit established the Himalayan Cataract Project in 1995 – with a vow to work to eliminate all preventable and treatable blindness from the Himalayan region in their lifetime, a goal, in Tabin’s words, “more audacious than setting out to make the first assent of the East Face of Mount Everest.” Dr. Ruit, whom the Associated Press heralded as the “god of sight” to the world’s poor, and Tabin have proven that hospital quality standards can be applied in impoverished areas devoid of electricity and clean water. Their successful approach to restoring sight and dogged perseverance has made possible what 20 years ago seemed impossible.
The Himalayan Cataract Project has since expanded beyond the Himalayas to encompass Sub-Saharan Africa as well. Dr.Tabin spends a considerable part of the year working abroad throughout the Himalayas and Sub-Saharan Africa. At Stanford his practice focus encompasses surgery and treatment of diseases of the anterior and external eye including cataract and corneal surgery. -

Karen Wai, MD
Clinical Assistant Professor, Ophthalmology
BioDr. Wai is a board-certified ophthalmologist and fellowship-trained vitreoretinal surgeon with Stanford Health Care Byers Eye Institute. She is also a clinical assistant professor of ophthalmology in the Department of Ophthalmology at Stanford University School of Medicine.
Dr. Wai is a retina specialist who diagnoses and treats retinal and macular diseases, including age-related macular degeneration, diabetic retinopathy, retinal vascular occlusions (blockages), and retinal tears/detachments. The retina is a tissue layer in the back of the eye. It converts light into signals that the brain then interprets as images. The macula is the part of the retina responsible for central (straight ahead) vision. Diseases of the retina and macula can cause low vision and vision loss.
Dr. Wai’s research interests include working with data from electronic health record databases to improve patient outcomes. She has researched morbidity and mortality (illness and death) rates in patients with retinal vein occlusions and retinal artery occlusions. A retinal vein occlusion is a blocked vein to the retina that can cause vision loss. A retinal artery occlusion is when an artery to the retina is blocked, which is also sometimes referred to as eye stroke. Dr. Wai has also examined the effects of systemic medications on the retina. She has won several ophthalmology awards, including the Heed Fellowship and Harvard Medical School’s Excellence in Clinical Instruction Resident Award.
Dr. Wai has published in more than 40 peer-reviewed journals, including Ophthalmology, American Journal of Ophthalmology, and JAMA Ophthalmology. She has presented research at meetings and conferences around the United States.
Dr. Wai is a member of the American Board of Ophthalmology. -

Sui Wang, PhD
Associate Professor of Ophthalmology
Current Research and Scholarly InterestsOur research focuses on unraveling the molecular mechanisms underlying retinal development and diseases. We employ genetic and genomic tools to explore how various retinal cell types, including neurons, glia, and the vasculature, respond to developmental cues and disease insults at the epigenomic and transcriptional levels. In addition, we investigate their interactions and collective contributions to maintain retinal integrity.
1. Investigating retinal development:
We utilize genetic tools and methods such as in vivo plasmid electroporation and CRISPR to dissect the roles of cis-regulatory elements and transcription factors in controlling retinal development.
2. Understanding diabetes-induced cell-type-specific responses in the retina:
Diabetes triggers a range of multicellular responses in the retina, such as vascular lesions, glial dysfunction, and neurodegeneration, all of which contribute to retinopathy. We delve into the detailed molecular mechanisms underlying these diabetes-induced cell-type-specific responses and the pathogenesis of diabetic retinopathy.
3. Developing molecular tools for labeling and manipulation of specific cell types in vivo:
Cis-regulatory elements, particularly enhancers, play pivotal roles in directing tissue- and cell-type-specific expression. Our interest lies in identifying enhancers that can drive cell type-specific expression in the retina and brain. We incorporate these enhancers into plasmid or AAV-based delivery systems, enabling precise labeling and manipulation of specific cell types in vivo. -

Charles Yu MD
Assistant Professor of Ophthalmology
Current Research and Scholarly InterestsCorneal opacity is a leading cause of blindness. Cornea transplantation is at high risk of rejection when there is pre-existing vascularization of the cornea and in pediatric patients. Cornea transplant shortage remains a worldwide problem with millions on waitlists. Our laboratory is developing multiple strategies for treatment of corneal blindness. We are testing advanced materials and designs for keratoprostheses with the goal of reducing complications and easing surgical implantation. We are also developing intraocular electronic display prostheses for bypassing cornea opacity, a novel strategy that could allow for high quality vision without corneal clarity.
