If you have been considering your laser vision correction options, you’ve likely heard about two popular options: SMILE and LASIK. While both procedures can correct common refractive errors, there are notable differences between the two.
Achieving the best possible visual outcomes depends on selecting the procedure that aligns perfectly with your unique eye anatomy, lifestyle needs, and vision goals. Keep reading to learn more about the differences between SMILE and LASIK and how to determine which may be best for you.
What is SMILE?
SMILE, which stands for Small Incision Lenticule Extraction, is a laser vision correction procedure that uses some of the most advanced laser technology to correct vision. It can correct vision in those who have myopia (nearsightedness) and astigmatism.
During a SMILE procedure, a laser is used to make a tiny incision on the edge of the cornea. Incisions created with this advanced laser are very controlled and precise, reducing the impact on surrounding tissue.
Using the incision to access the middle layer of the cornea, the femtosecond laser creates a disk of corneal tissue, called a lenticule. This process reshapes the cornea to correct refractive errors.
Once the lenticule is removed, the procedure is complete. The incision naturally heals on its own, without the need for stitches.
Good candidates for SMILE are at least 22 years old with a prescription that has been stable for a year or more. SMILE is best for individuals with no more than -10 diopters of myopia and up to 3 diopters of astigmatism.
What is LASIK?
LASIK is the most well-known and commonly performed laser vision correction procedure available. It can correct the most common refractive errors, including myopia, hyperopia (farsightedness), and astigmatism.
During a LASIK procedure, a flap is created on the surface of the cornea using a laser. The flap is gently pushed back to access tissue in the middle layer of the cornea.
Corneal tissue is removed and reshaped using a different laser, allowing light entering the eye to correctly focus on the retina. The flap is then moved back into place, where it heals on its own during recovery.
To qualify for LASIK, an individual must be at least 18 years old with a stable prescription of at least a year, adequate corneal thickness, and overall healthy eyes. LASIK has the potential to correct up to -12 diopters of myopia, up to +6 diopters of hyperopia, and 6 diopters of astigmatism.
How Do I Know Which Procedure is Better for Me?
You likely won’t know for certain which procedure might be best for you until you undergo a comprehensive candidacy evaluation with a qualified eye doctor. While online research and comparisons are helpful starting points, the determination between SMILE and LASIK ultimately comes down to your unique eye anatomy, health history, and lifestyle factors that can only be assessed through a detailed examination.
The candidacy process is far more than a simple vision test. During your evaluation, your eye doctor will measure your corneal thickness, map the curvature of your cornea, assess your tear film quality, and examine the overall health of your eyes.
They’ll also review your medical history, current medications, and discuss your daily activities. This comprehensive assessment is what makes laser vision correction both safe and effective.
Some patients discover they’re an ideal candidate for both procedures, giving them the luxury of choice based on personal preferences. Others learn that their corneal thickness, prescription strength, or dry eye condition makes one procedure clearly better for them than the other.
Your eye care provider acts as your personal matchmaker in this process, weighing dozens of factors you might not even consider. They can explain what you’re likely to experience with each procedure and help you understand how the differences between SMILE and LASIK will specifically impact your situation.
Remember, the goal isn’t just to achieve clear vision, it’s to achieve the best possible vision correction safely and effectively for your individual circumstances.
