Meet Dr. Andrew Bainnson


Dr. Bainnson is a Long Island native having grown up in Plainview. The eye doctor graduated from the University of Michigan with honors with a degree in cellular and molecular biology followed by medical school at SUNY Downstate in Brooklyn. During college and medical school he also performed pharmacology research at the University of Michigan and published his results in the Journal of Pharmacology.

Dr. Bainnson’s clinical training started with a transitional year at Columbia affiliated Overlook Hospital in Summit New Jersey. As part of this year he spent 3 weeks at Moorfields Eye Hospital in London, England. His ophthalmology residency was completed at New York Medical College where he served as Chief Resident during his final year. During residency he presented research papers on laser cyclophotocoagulation therapy for glaucoma as well as corneal research regarding pterygium treatment at ARVO (which is an international conference centered on vision and ophthalmology) as well as at the American Academy of Ophthalmology Annual meeting. After completing his residency he completed a fellowship in Glaucoma and Anterior Segment surgery at the Kellogg Eye Center of the University of Michigan. While at the Kellogg Eye Center Dr. Bainnson was involved in the teaching of ophthalmologists in training at the University of Michigan and the Ann Arbor VA Hospital.

Dr. Bainnson’s philosophy about caring for patients centers on his desire to develop long-term relationships with his patients. To him, ophthalmology provides a great opportunity to care for patients of all ages and from all backgrounds and then really make a difference in their lives. He remembers how clearly he saw after obtaining his first pair of glasses and how much of a difference it made to him. His interest in glaucoma was sparked while he was an ophthalmology resident at New York Medical College. While glaucoma does not have any clear cut symptoms at first it can result in profound vision loss. By educating his patients about glaucoma and its treatment his patients learn not to fear having a diagnosis of glaucoma. So much of glaucoma care centers around patient and doctor being on the same page with regard to treatment goals and how to get there. While glaucoma can sometimes be challenging and difficult to control, being able to report to his patients that they are doing well and not losing vision provides Dr. Bainnson with great satisfaction.

Dr. Bainnson is a fellow of the American Academy of Ophthalmology, New York Ophthalmological Society and the Suffolk County Ophthalmological society. Previously on staff at Southside Hospital and Good Samaritan Hospital he now is awaiting staff appointment to St Catherine of Siena Hospital in Smithtown. He and his wife Marsha, who is an optometrist, have two teenagers. In his spare time he enjoys traveling, gardening and bicycling.
