Dr. Leahy grew up here and he and his wife Teresa have raised three children in Concord, who attended the Concord schools and have gone on to attend Boston College, Holy Cross and West Point.

After completing his medical training in primary eye care in Boston at the New England College of Optometry, Dr. Leahy pursued a research degree in physiological optics from U. Cal Berkeley. Since then, Dr. Leahy has consulted with major contact lens companies, and performed clinical research studies on behalf of contact lens manufacturers, ophthalmic clinical research organizations, and for the FDA. He has invented and continues to develop a device for ophthalmic drug delivery.

While Dr. Leahy specializes in contact lenses, routine eye care is provided as well. We can offer testing for glaucoma, cataracts, dry eyes and macular degeneration. If you are looking for surgical care for cataracts, laser vision correction or corneal disease, he can provide an objective assessment of your condition and recommend the best surgeons to manage your specific needs.

His primary practice is at the Massachusetts Eye & Ear Infirmary in Boston, where he is nationally recognized for his skill and expertise in contact lens fitting and management of complex corneal cases, such as keratoconus, corneal transplants, astigmatism, allergies and dry eye. While he specializes in the complex, long-term success with routine contact lens wear is a special interest of his, and he spends much time educating patients with that goal in mind for them. As an Assistant Professor of Ophthalmology for Harvard Medical School, he teaches ophthalmology and optometry residents.

Because of his research specialty, he is frequently one of the first to offer newer lens product introductions to his patients, such as daily disposable, sports performance, astigmatism or bifocal lenses, and custom made lenses for problem fits. We offer the full service optical of Concord Optical for people that use both contact lenses and glasses.

Should patients need access to specialty testing or diagnostic lens designs, Dr. Leahy can see them in Boston and then follow them here locally.

He offers convenient phone or online replacement ordering for lenses to be delivered to your door, and updates the contact lens information for you online after each visit.
