Eye Care Specialists - Topic Overview

Ophthalmologists are medical doctors (MDs) who specialize in eye care. Ophthalmology is a surgical subspecialty. Ophthalmologists are licensed by state medical boards to practice medicine and are usually board-certified in ophthalmology. Ophthalmologists are certified to:

Ophthalmologists can diagnose all disorders that affect the eye. They can carry out any medical or surgical treatment.

In a few states, even where they are allowed to administer diagnostic drugs, optometrists are not allowed to diagnose or treat eye disease. They may observe signs of disease and refer you to an ophthalmologist.

On average, optometrists charge less for routine eye exams than ophthalmologists. You may also be able to get an appointment with an optometrist sooner than with an ophthalmologist. Optometrists are more likely than ophthalmologists to offer evening and weekend appointments.
