Many vision patients wonder: What is the difference between an M.D. and an O.D.?
An M.D. is a Medical Doctor, and in the eye medicine field, an M.D. is called an ophthalmologist. An O.D. is a Doctor of Optometry and is called an optometrist.
Ophthalmologists are trained to provide a comprehensive range of eye care, including the diagnosis and treatment of serious eye diseases. They are also trained to perform complex eye surgeries and conduct eye care research.
After receiving a bachelor’s degree, ophthalmologists spend four years in medical school and complete a one-year internship. They then complete a minimum of three years of residency (training in a hospital setting). Many also spend an additional two to three years in training for a further specialty, such as pediatric ophthalmology.
In contrast, optometrists are trained specifically to diagnose and treat eye conditions, like nearsightedness, farsightedness and astigmatism. Optometrists can perform complete eye exams and prescribe glasses, contacts and some eye care medications.
After receiving a bachelor’s degree, optometrists complete four years of training to obtain an optometry degree. Some may also complete a one-year clinical residency.
