Kevin J. Chaisson, O.D.

Dr Kevin Chaisson | Optometrist Rochester NYAs a graduate of the University of Rochester, in Microbiology, Dr. Kevin Chaisson chose the path of eye care because of his firm belief that the eyes are one of the greatest gifts we are given. He went on to receive his Bachelor of Science in Visual Sciences from the Pennsylvania College of Optometry graduating in 1989 and continued on to receive his Doctor of Optometry degree in 1992. His strongest belief is that most vision loss for most patients can be easily prevented with ongoing comprehensive eye care throughout a patient's lifetime.

During his final years at the University of Rochester, Dr. Chaisson was employed by the Rochester Eye & Human Parts Bank where he harvested eyes from donors to be used for transplants. Giving the gift of sight to patients who otherwise would have suffered substantial vision loss was truly rewarding and further cemented his decision to pursue a career in Optometry.

Patients are immediately at ease with Dr. Chaisson due to his innate ability to make them feel comfortable, and his way of explaining their ocular health in a manner that is simple to understand. Dr. Chaisson states,  I encourage my patients to ask questions about their eye health; the more a patient understands his or her condition, the better opportunity for the doctor and patient to design an effective treatment plan that is in the best interest of the patient.

Dr. Chaisson provides unparalleled comprehensive eye care. Services provided by him include, but are not limited to; eye health examinations, specialty contact lens evaluations and treatment of ocular diseases. He is an integral part of the Cornerstone Refractive Team providing consultations that determine a patient s candidacy for surgery as well as providing postoperative care.
