No Touch Laser Surgery (Trans PRK)


In conventional laser treatments that have been in use for a long time to get rid of glasses and contact lenses the eye must be “touched”. This can cause anxiety in patients who choose to have laser surgery. The laser method called TransPRK (No Touch Laser) technique prevents this worry. There is no contact with the laser device in this method. It is enough for the patient to look at a remote light source for seconds for treatment to be completed.

What is the difference between TransPRK (No Touch Laser) method and other laser treatment methods? In classical treatment methods LASIK andintraLASIK (femto-second) techniques, the corneal tissue in the eye is cut with a special knife or laser and then treated. In the PRK method, the front wall of the eye is eroded with alcohol and then treated. In the  No Touch Lasertreatment this is not done, treatment takes place in one step. In this method, it is sufficient to look at a distant light source for less than 50 seconds. This method reduces the risk of high-grade astigmatism and surgery-related progressive corneal dilation called ectasia, which is seen after LASIK and femtosecond (intraLASIK, i-LASIK) treatments to zero. In addition, the risk of retinal rupture, which can be caused by the vacuum (suction) ring, which is applied in the LASIK and femtosecond methods, is completely eliminated.

Which patients can this method be applied to? Can be applied to those with myopia, hypermetropia and astigmatism whose eye structure is suitable. So, patients with far and near sightedness may be candidates for this treatment.  In some cases, No Touch Laser treatment can be the only way to solve the problem, especially in cases of thin cornea and normal corneal surface.

How is the application carried out? No Touch Laser treatment is carried out with only anaesthetic drops, and the patient does not feel any pain during application. There is no device contact with the eye during the treatment, direct treatment is performed with the rays emitted from the laser device. After the treatment, the eyes do not have to be closed, the patient can go home with both eyes open. The treatment is performed on both eyes in the same treatment session. After going home, the patient develops complaints such as stinging in the eyes, flushing, disturbing light and blurred small text on TV for 36 hours. On the fourth day after the treatment, the patient may begin to work on the computer and drive.

What is the application in night vision problems? In wavefront practice, also known as ‘eagle eye’ colloquially, light scattering and deviations in the eye are measured and laser treatment is adjusted accordingly. When these deflections which cannot be corrected even with glasses or lenses are corrected with the wavefront technique, appropriate treatment for the eye structure of the person is achieved. As a result, the night vision of the patient increases and the complaints of the dazzling type produced by the car headlights coming at night come to an end.

Why No Touch Laser?

  • Treatment occurs without eye contact with the machine.
  • Treatment is completed within seconds.
  • The membrane is not lifted from the eye, the eye is not scored, parts are not removed from the eye.
  • The epithelium that covers the eye is not cleaned with alcohol, and epithelial excavation is not performed.
  • There is no pain during treatment.
  • The two eyes are treated in the same session.
  • Eyes are not closed after treatment.
  • Patients with thin cornea can be treated.
  • Ectasia risk is next to zero.
  • The risk of retinal tear is zero.
  • Membrane crumpling, cell accumulation under the membrane problems do not occur.
  • Can be applied to those with myopia, hypermetropia and astigmatism.
  • The post-treatment eye dryness is of low severity and is transient.

While long term protection of the eyes is required in treatment such as LASIK, femto-second, this kind of protection is no longer required following No Touch Laser treatment after 3-4 days.

It is possible to enter the sea and the pool from the 7th day after the treatment.
