What's the Difference Between LASIK and SMILE Eye Surgery?
&srotate=0)
Laser vision correction has advanced remarkably over the last two decades, giving patients multiple options for reducing or even removing their dependence on glasses and contacts. Two of the most well-known procedures are LASIK and SMILE laser eye surgery. Both treatments are highly effective, but they differ in technique, recovery, candidacy, and other aspects. At Wang Vision Institute in Nashville, TN, Dr. Ming Wang, a Harvard & MIT graduate who holds a doctorate degree in laser physics, and our team are proud to offer both LASIK, including the specialized Soft-Touch LASIK, and ZEISS SMILE, the first minimally invasive, flapless laser vision correction procedure approved in the United States. In fact, we were the first center in the state to perform SMILE —a small-incision LASIK procedure. Understanding the differences between LASIK and SMILE eye surgery can help you make a confident decision about your vision.
What happens during LASIK eye surgery?
LASIK is the most widely known type of laser vision correction and has helped millions of patients achieve clearer eyesight. The procedure involves creating a thin corneal flap, gently lifting it, and then using an advanced laser to reshape the underlying corneal tissue. This adjustment allows light to focus properly on the retina, improving vision. At Wang Vision Institute, our team performs Soft-Touch LASIK, which uses state-of-the-art technology to create an ultra-thin, precise flap with minimal disruption. This technique provides improved comfort, accuracy, and safety compared to traditional LASIK approaches. Recovery is typically quick, with many patients noticing better vision within hours of the procedure.
How does SMILE laser eye surgery differ from LASIK?
SMILE, which stands for Small Incision Lenticule Extraction, is often referred to as the next generation of laser vision correction. Unlike LASIK, SMILE does not require the creation of a corneal flap. Instead, a femtosecond laser creates a tiny lens-shaped piece of tissue (lenticule) within the cornea. That tissue is then removed through a micro-incision just a few millimeters wide. By avoiding flap creation, SMILE reduces the risk of flap-related complications and preserves more of the cornea's natural strength. Because the incision is so small, recovery can feel smoother, and there may be less postoperative dryness compared to LASIK. SMILE has become an attractive option for patients with active lifestyles who want a minimally invasive approach.
Does LASIK cause dry eyes?
One of the most common questions patients ask is how LASIK and SMILE compare when it comes to dryness. While LASIK is safe and effective, the creation of a corneal flap can sometimes contribute to temporary dry eye symptoms. SMILE, with its small incision and no flap, tends to have a lower risk of dryness after laser eye surgery. This difference makes SMILE a strong choice for patients who already struggle with dry eye syndrome or who want to minimize that possibility. However, each patient's eyes are unique. During your consultation, Dr. Wang and our team will evaluate individual factors to determine which procedure fits your needs.
Who is a candidate for LASIK vs. SMILE?
Both LASIK and SMILE are designed to correct nearsightedness and astigmatism, though LASIK can also treat farsightedness, which SMILE currently does not. Candidacy for each type of laser eye surgery depends on several individual factors, including:
- Vision prescription
- Corneal thickness
- Dry eye history
- Lifestyle and activities
- Desired recovery experience
Again, during your private consultation with Nashville LASIK surgeon Dr. Wang, you'll undergo a thorough examination and discussion of your full health and vision history so that Dr. Wang can make a customized treatment recommendation that sets you up for the most successful procedure and optimal outcome possible.
