"Depending on the complexity of their condition—and the period of time that you treat them—a good doctor should do more than impart medical advice to patients. You are a source of comfort, stability and sometimes, even a confidant. And you don't learn that in med school; your patients actually teach you."
Dr. Johnson received his medical degree from the University of Western Ontario, where he was presented with the Hewlett Packard Award as the school’s top medical graduate. He completed his residency at the University of Ottawa Eye Institute, followed by a fellowship in Vitreoretinal Surgery and Uveitis at the University of Michigan’s Kellogg Eye Institute.
Prior to joining The Retina Group of Washington, Dr. Johnson spent nine years as an attending surgeon at the National Retina Institute. He has been quite active in research and education in the Vitreoretinal field, having given lectures to both local and international groups and published numerous articles in peer-reviewed journals. He serves as a reviewer for Retina, Ophthalmology and the American Journal of Ophthalmology, and also is editor of “Evidence Based Eye Care,” a standard textbook used in ophthalmic training programs. He has contributed chapters to numerous other textbooks on macular surgery, retinal detachment repair, ocular trauma, diabetic retinopathy, treatment of macular degeneration and advanced retinal imaging.
Dr. Johnson is a fellow of the Royal College of Surgeons and is board certified by the American Board of Ophthalmology. He is a trilinguist (English, Spanish and French) who is licensed to practice in Maryland, Virginia and Washington, D.C. He is president elect of the Washington DC Metropolitan Ophthalmological Society, and a member of the American Academy of Ophthalmology, the Canadian Ophthalmological Society and the American Society of Retinal Specialists.
