LASIK vs. SMILE/CLEAR: Which Laser Vision Correction Procedure Is Best?

For those seeking freedom from glasses and contact lenses, laser vision correction offers multiple options. Two of the most advanced procedures available today are LASIK and SMILE/CLEAR. While SMILE and CLEAR are essentially the same technique under different names, they differ from LASIK in key ways that may influence your choice.

In this article, we’ll compare LASIK to SMILE/CLEAR, their benefits, and who they’re best suited for.

 Understanding the Procedures

LASIK (Laser-Assisted In Situ Keratomileusis)

LASIK is the most well-known laser eye surgery, using a femtosecond laser to create a thin flap on the cornea. The underlying tissue is then reshaped with an excimer laser to correct refractive errors before the flap is repositioned.

Pros:

- Quick recovery time (usually within 24 hours)

- Effective for a wide range of refractive errors (myopia, hyperopia, and astigmatism)

- Painless procedure

- Modern “topography guided” or “ray-tracing” techniques can offer exceptionally good outcomes

Cons:

- May cause temporary dry eyes

- Flap-related complications are very rare but possible

Best suited for:

- Those looking for a fast recovery

- Individuals without significant dry eye issues

SMILE/CLEAR (Small Incision Lenticule Extraction)

SMILE and CLEAR are essentially the same procedure, involving the removal of a small, lens-shaped piece of corneal tissue (lenticule) through a keyhole incision. This reshapes the cornea and corrects vision without the need for a flap.

Pros:

- Minimally invasive (no flap creation)

- Less risk of dry eye compared to LASIK

- More biomechanical stability of the cornea

Cons:

- Limited ability to correct hyperopia (farsightedness) or astigmatism

- Longer recovery time than LASIK

Best suited for:

- Patients with moderate to high myopia (-2.00 to -9.00 D)

- Individuals prone to dry eyes

- Athletes or those in contact sports (lower risk of flap displacement)

Which One Is Best for You? 

- Choose LASIK if you need quick recovery and have no major dry eye concerns.

- Choose SMILE/CLEAR if you want a flapless, minimally invasive procedure with reduced dry eye risk.
