Dr. Lou Pizzarello

Dr. Pizzarello has practiced ophthalmology on the East End of Long Island for thirty years. After a childhood spent in Southampton, he earned a bachelor’s degree at Colgate University, medical degree at the University of Virginia and a degree in public health from Harvard University. He completed an internship at the Toronto General Hospital and a residency in ophthalmology at the E.S. Harkness Eye Institute at Columbia University.

During his time in practice, Dr. Pizzarello has treated many patients with complicated eye diseases. He is particularly interested in cataract and corneal surgery as well as ophthalmic plastic surgery. Using one of the first lasers on Long Island, he continues to perform a wide range of laser procedures for retinal disease and glaucoma. He has one of the most extensive surgical experiences on Long Island.

As author of over 30 scientific papers, he has written on a wide range of topics including cataract surgery, children’s eye disease and blindness prevention. He has served as President of the Medical Staff of Southampton Hospital as well as a Board member of the hospital and East End Hospice. Dr. Pizzarello has worked in over 40 countries bringing eye care to underserved people and initiated a project to provide inner city children with glasses in the US. He has received awards from the International Agency for the Prevention of Blindness, Helen Keller International, Southampton College and the American Academy of Ophthalmology. He is Professor of Ophthalmology and Health Management at Columbia University, which allows him to be involved continually in the latest developments in ophthalmology. Many of these technologies have been incorporated into the practice.

Frequently Asked Questions

Are "flashing lights" an emergency?

It is very common to develop a new onset of something appearing in your vision, like a flying insect. This may be associated with lightening-like flashes of light in the side of your vision. No need to panic. Unless you sight has been diminished this problems can wait a few days and can be evaluated in the office. Should you notice a dramatic drop in your vision, you should call the office as soon as possible.

What are the symptoms of cataract?

Cataracts are a clouding of the lens of the eye. They are very common as one ages. Seldom do they change vision overnight, rather they slowly progress over months or years. The main symptoms are glare when driving at night or difficulty seeing when looking toward a bright light. The good news is that they can be treated with a short operation that can fully restore your sight, frequently without the need for glasses. Call our office at 631-727-6555 or 631-283-5152 for an appointment if you have noticed symptoms or if you have been told you need cataract surgery.
