This is one of the most important distinctions to understand when researching vision correction surgery. The two titles sound similar but represent fundamentally different education, training, and scope of practice.
The Direct Answer
Ophthalmologists are medical doctors (MD or DO) who completed medical school plus a 3-year ophthalmology residency, and often additional fellowship training. They are licensed to perform surgery. Total training: 12-14 years post-secondary.
Optometrists are Doctors of Optometry (OD) who completed a 4-year optometry school program. They examine eyes, prescribe glasses and contact lenses, and in many states can prescribe certain medications. They are not licensed to perform surgery. Total training: 8 years post-secondary.
Who performs LASIK, PRK, and EVO ICL? Ophthalmologists only. This is non-negotiable.
Where Optometrists Fit in the Care Process
Optometrists play a valuable role in the refractive surgery care model:
- Referring patients for surgical consultation — often optometrists know which surgeons in a market they trust with their patients
- Pre-operative screening — initial evaluation of whether a patient might be a candidate
- Post-operative co-management — routine follow-up visits after the critical early period
What optometrists do not do and should not do in your care:
- Make the final candidacy determination for surgery
- Perform the procedure
- Manage surgical complications without ophthalmologist oversight
When evaluating any practice, confirm: who performs the surgery, and who is the ophthalmologist responsible for your care if a complication occurs.
Why This Matters When Choosing a Provider
Some vision correction chains use optometrists for nearly all patient-facing interactions, with the ophthalmologist present only for the brief surgical procedure itself. This fragmentation of care can create problems if complications arise. Continuity with a qualified physician throughout your care episode is associated with better management of unexpected findings.
