An ophthalmologist diagnoses and treats a wide range of eye conditions, including cataracts, glaucoma, retinal disorders, diabetic retinopathy, macular degeneration, and refractive errors like myopia and astigmatism.

You should see an ophthalmologist for routine eye exams, sudden changes in vision, eye pain, floaters, flashes of light, blurred vision, or any eye injury. People with diabetes, hypertension, or a family history of eye disease should have regular check-ups.

Ophthalmologists are medical doctors (MD or DO) trained to perform eye surgery and treat complex eye diseases. Optometrists provide vision care, prescribe glasses or contact lenses, and manage some eye conditions, but do not perform surgery.

A retina specialist is an ophthalmologist who has additional training in diagnosing and treating retinal disorders, such as retinal detachment, diabetic retinopathy, macular degeneration, and other conditions affecting the back of the eye.

Ophthalmologists perform surgeries including cataract surgery, retinal surgery (for detachment, macular holes), glaucoma surgery, corneal transplants, and laser eye procedures.

Adults should have a comprehensive eye exam at least every 1–2 years, or more frequently if they have chronic conditions like diabetes, hypertension, or a family history of eye disease.
