Ophthalmologist vs. Optometrist: Who Should You See and When?

If you’re comparing eye doctors in Marietta—whether you need a routine exam, have cataracts on the horizon, or simply want a second opinion before eye surgery—understanding the distinct roles of ophthalmologists and optometrists will help you choose the right provider.
Here, board-certified Marietta ophthalmologist & fellowship-trained glaucoma specialist Jordan Stanley, MD explains.
What is an optometrist?
Optometrists are the primary eye care providers for most people—offering routine eye exams, glasses and contact lens prescriptions, and screening for conditions that may require more advanced medical or surgical treatment.
Typical Services You’ll Receive:
- Glasses and contact lens prescriptions
- Screening and treatment for dry eye, red eye, ocular allergies, and early glaucoma
- Minor in‑office procedures (for example, removing a foreign body or draining a stye)
Degree & Training: Doctor of Optometry (OD) earned after four years of optometry school following college; some also complete a one-year residency.
An optometrist is often the best first stop for preventive vision care, while an ophthalmologist is the only eye‑care provider qualified to perform surgery and manage complex diseases.
What is an ophthalmologist?
Ophthalmologists are medical doctors specializing in surgical and advanced medical eye care—including diagnosing complex conditions and managing diseases that affect vision, such as glaucoma, cataracts, and diabetes-related eye disease.
Typical Services You’ll Receive:
- Diagnosis and management of all eye diseases, including complex glaucoma and retinal disorders
- Cataract, glaucoma, corneal, and refractive surgeries
- Prescriptions for any eye‑related medications, plus glasses and contacts
Degree & Training: Medical Doctor (MD) or Doctor of Osteopathic Medicine (DO) who completes four years of medical school, a one‑year internship, and a minimum three‑year ophthalmology residency; many pursue additional subspecialty fellowships.

When to See an Optometrist vs. an Ophthalmologist
See an optometrist for …
- Annual or biannual comprehensive eye exams
- Updating glasses or contact‑lens prescriptions

PureSight Surgical Gives You Direct Access to Advanced Care
Most patients already have a trusted local optometrist—the one who’s cared for them and their families for years. But when surgery becomes necessary, they’re often referred to large, corporate eye-care systems where pricing is unclear and care can feel impersonal.

PureSight Surgical is different in several ways:
- Direct Surgeon Access: You meet Dr. Stanley from day one.
