What is an Eye M.D. (Ophthalmologist)?


Ophthalmology is a branch of medicine specializing in the anatomy, function and diseases of the eye. An Eye M.D. is an ophthalmologist, a medical doctor who specializes in eye and vision care. Eye M.D.s are specially trained to provide the full spectrum of eye care, from prescribing glasses and contact lenses to complex and delicate eye surgery. Many Eye M.D.s are also involved in scientific research into the causes and cures for eye diseases and vision problems.

Education & Training


In addition to four years of medical school and one year of internship, every Eye M.D. spends a minimum of three years of residency (hospital-based training) in ophthalmology. During residency, Eye M.D.s receive special training in all aspects of eye care, including prevention, diagnosis and medical and surgical treatment of eye conditions and diseases.

Often, an Eye M.D. spends an additional one to two years training in a subspecialty, that is, a specific area of eye care (for example, glaucoma or pediatric ophthalmology).
