He maintains an active clinical practice focusing on cornea, cataract, and refractive surgery.  

Tyson N. Kim, MD, PhD is Assistant Professor of Ophthalmology at UC San Francisco and core member of the Joint Group in Bioengineering at UCSF/UC Berkeley. He completed his bachelor’s degree in physics, medical degree at UCSF, and his PhD in bioengineering at UCSF/UC Berkeley. He went on to complete residency at the University of Michigan Kellogg Eye Center and fellowship in cornea, external disease, and refractive surgery at the Bascom Palmer Eye Institute.
 
Dr. Kim is deeply committed to providing excellent patient care, as well as innovating new technologies to improve vision and human health. He leads a cross-disciplinary team of engineers and biomedical researchers with a major focus on advanced optics and developing tools for refractive surgery and treatment of ophthalmic diseases. Dr. Kim has published articles in the areas of vascular biology, advanced imaging, adaptive optics, and femtosecond laser applications. He is a reviewer for several leading journals of ophthalmology and applied optics.

Julie Schallhorn, MD, MS is Associate Professor of Ophthalmology at UCSF. Dr. Schallhorn received her undergraduate degree in Chemical Engineering from UCLA, and her Master’s degree in Bioengineering from UCSD. She then completed medical training at the University of Southern California Keck School of Medicine, and her ophthalmology residency at UCSF. She went on to fellowship training in Uveitis at the F.I. Proctor Foundation at UCSF, and in Cornea at the Casey Eye Institute in Portland, Oregon. She was on faculty at the University of Southern California’s Roski Eye Institute before returning to San Francisco and UCSF.
 
Dr. Schallhorn has strong research interests in the study and improvement of refractive surgery outcomes, and is deeply invested in obtaining the best possible results and experiences for her patients. She has authored numerous peer-reviewed articles on visual outcomes, ocular surface disease, and patient satisfaction after refractive surgery. She currently sits on the Ophthalmic Technology Assessment Committee for Refractive Surgery for the American Academy of Ophthalmology, and is a reviewer for many of the leading journals in the field.

Madeline Yung, MD is an Assistant Professory of Ophthalmology at UCSF. Dr. Yung received her undergraduate degree in Neuroscience at UCLA. She completed medical training at the David Geffen School of Medicine at UCLA, and her ophthalmology residency at the Jules Stein Eye Institute at UCLA. She went on to complete a cornea fellowship at the UC Davis Eye Center.
 
Dr. Yung is committed to providing the highest standards of care for her patients. She has authored numerous peer reviewed publications in the field of cornea and external disease, and is currently pursuing research on the use of digital technology to improve the patient experience.

Simon S. M. Fung, MD, MA(Oxon), FRCOphth

Associate Professor of
Clinical Ophthalmology

Simon S. M. Fung, MD, MA, FRCOphth, is an Associate Professor of Ophthalmology at UCSF. He received his medical degree from the University of Oxford and completed his ophthalmology residency and a fellowship in cornea, cataract, external disease and refractive surgery at Moorfields Eye Hospital in London. He subsequently completed further fellowship training in paediatric cornea and external disease at The Hospital for Sick Children in Toronto.
 
Before joining UCSF, Dr Fung was a faculty member at the UCLA Stein Eye Institute. His clinical practice includes laser vision correction, cataract surgery and the management of complex corneal and ocular surface disease. He has published extensively in the field of cornea and regularly lectures nationally and internationally. Dr Fung is committed to providing careful, individualised recommendations and helping patients select the vision correction option best suited to their eyes and personal goals.
