Strabismus Surgery

Dean Cestari Dean M. Cestari, MD

Dr. Cestari is an Assistant Professor of Ophthalmology at Harvard Medical School, as well as Director of Ophthalmology Clinical Fellowship Training and Co-director of the Center for Thyroid Eye Disease and Orbital Surgery at Mass. Eye and Ear. He is one of only a handful of doctors in the country who is board-certified in both neurology and ophthalmology. Because Dr. Cestari understands the complicated interactions between the eye and the brain, he is able to provide care for patients with a wide variety of conditions, such as optic nerve disorders, misaligned eyes (strabismus), double vision, and increased pressure around the brain. Many patients come to him with double vision, and depending on the cause, he provides different treatments such as prism eyeglass lenses, Botox injections, and/or strabismus surgery. All surgeries are performed with the adjustable suture technique, which allows him to fine-tune the procedure while the patient is awake to ensure the double vision is eliminated and the eyes are aligned.
