Dr. Sonsino studied at the New England College of Optometry in Boston, where he graduated with research honors. He had the opportunity to spend time at and complete a research poster at the Massachusetts Eye and Ear Infirmary, Harvard Medical School. Afterward, he completed a highly competitive one-year residency in cornea and contact lenses at Illinois College of Optometry. In Chicago, he worked mainly with the optometrist and ophthalmologists at the prestigious, University of Chicago Medical Center seeing patients with severe corneal diseases. One highlight of his experience there was super-gluing a patient’s cornea closed to save his vision.
After residency, he became faculty at the Vanderbilt University Medical Center Eye Institute for 11 years where he lectured around the world, wrote 10 patents on novel ophthalmic devices, authored papers, and became the director of the optometry service. The experience he gained there was the foundation that advanced his standing nationally.
