SMILE Pro, PRK or LASIK: What Are the Differences?

Yazar: Op. Dr. Gökay Günay

One of the most common questions among people researching laser eye surgery is:

“What is the difference between SMILE Pro, PRK and LASIK?”

Online research may often suggest that one method is better than another.

However, the most appropriate approach in eye surgery is different.

The aim is not to find the “best” method overall, but to identify the method best suited to your eye structure.

What Is SMILE Pro?

SMILE Pro is a modern laser method in which a thin layer of tissue created within the cornea is removed through a small incision.

Because no corneal flap is created, it may offer important advantages for some patients.

It is widely used particularly for the treatment of myopia and myopic astigmatism.

What Is LASIK?

In LASIK, a thin corneal flap is created and the laser treatment is performed beneath this layer.

FemtoLASIK is a more modern form of LASIK in which the flap is created with a femtosecond laser.

These treatments have been used for many years and can provide successful outcomes.

What Is PRK?

PRK is one of the oldest methods of laser eye surgery.

In this method, the surface layer of the cornea is removed and the laser is applied directly to the corneal surface.

It remains an important treatment option in certain situations.

Which Method Is Better?

There is no universal answer to this question.

When making the decision, factors such as the following are assessed:

  • Corneal thickness
  • Corneal shape
  • Refractive error
  • Amount of astigmatism
  • Occupation
  • Sporting habits
  • Dry-eye status
  • Visual expectations

These factors are assessed together.

This is why two people of the same age with similar prescriptions may be advised to have different procedures.

Is the Newest Technology Always the Right Choice?

No.

Success in eye surgery does not depend solely on the technology used.

Selecting the right method for the right patient is often more important than the technology itself.

SMILE Pro may be the most suitable option for some people, while FemtoLASIK or PRK may be more appropriate for others.

Conclusion

SMILE Pro, PRK and LASIK are among the important treatment options in modern eye surgery.

However, each method has different advantages and limitations.

The decision should therefore be based not on technology alone, but on detailed measurements and an individualised assessment.

The aim is not to choose the most popular method, but to identify the safest and most suitable treatment for your eyes.
