SMILE Pro or No Touch Laser: What Are the Differences?

Yazar: Op. Dr. Gökay Günay

One of the questions most frequently asked by people who want to reduce dependence on glasses and contact lenses is:

“Should I have SMILE Pro or No Touch Laser?”

Many people researching online compare these two methods and try to determine which is better.

However, the more important question in eye surgery is different:

“Which method is more suitable for my eye structure?”

Because successful outcomes depend not on choosing the newest technology, but on applying the right treatment to the right patient.

What Is SMILE Pro?

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

Unlike conventional LASIK, this method does not involve creating a corneal flap.

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

What Is No Touch Laser?

No Touch Laser is essentially a laser treatment within the PRK family.

The term “No Touch”, which has become more common in recent years, is used to emphasise that the procedure is performed without mechanical contact with the eye.

In principle, No Touch Laser is not an entirely new type of surgery, but one of the modern applications of PRK, which has been used for many years.

What Is the Main Difference Between SMILE Pro and No Touch Laser?

The main difference is the way the laser treatment is performed.

With SMILE Pro, treatment takes place within the cornea, whereas with No Touch Laser, treatment is performed from the corneal surface.

For this reason:

  • Recovery processes may differ.
  • Comfort during the first few days may differ.
  • One method may offer advantages in certain eye anatomies.

However, this varies from person to person.

Which Is Better?

There is no single answer to this question.

When making the decision, the following should be considered together:

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

These factors should be assessed together.

For some people SMILE Pro may be the most suitable option, while for others No Touch Laser (PRK) may be the better choice.

Does the Newest Technology Always Give the Best Result?

No.

Success in eye surgery does not depend on technology alone.

The most important factors are appropriate patient selection and individualised treatment planning.

Sometimes a newer technology may be the right choice, while in other cases a different method may provide better long-term results.

Conclusion

SMILE Pro and No Touch Laser are modern laser treatments that can provide successful outcomes.

However, the most appropriate method is not the same for everyone.

What matters is not which method is more popular, but identifying which treatment is more suitable for your eye structure and lifestyle.

The decision should therefore be made after a detailed eye examination and comprehensive measurements.
