Short answer

The excimer laser is a laser system that corrects your prescription by reshaping corneal tissue in very thin layers with a “cold” ultraviolet beam. It is used in PRK, TransPRK and LASIK. Which of these suits you is decided by your corneal measurements.

What Is Excimer Laser Treatment?

Excimer laser treatment is a modern, precise laser procedure used to correct refractive errors of the eye. With this method, the cornea – the clear front layer of the eye – is reshaped at the micron level so that light focuses correctly on the retina.

Excimer laser technology is used especially to correct vision problems such as nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. It is the main treatment tool in common procedures such as LASIK and PRK. Planned individually and performed after assessment by a doctor, this treatment can provide good visual comfort in suitable candidates.

With its high precision and, in many cases, quick recovery, this treatment is a reliable option in eye care. Performed under an ophthalmologist’s supervision, excimer laser treatment aims to reduce the need for glasses or contact lenses in daily life.

Who Is Excimer Laser Treatment Suitable For?

Excimer laser treatment can be an effective option for people with certain refractive errors. Suitability is assessed by an ophthalmologist with a detailed eye examination. Excimer laser treatment may be considered in the following situations:

  • Myopia, or nearsightedness (blurry distance vision)
  • Hyperopia, or farsightedness (difficulty seeing up close)
  • Astigmatism (blurred or distorted vision)
  • Age 18 or older, with a glasses prescription that has been stable for the past year
  • Good general eye health and suitable corneal thickness

In suitable candidates, excimer laser treatment can sharpen vision and support quality of life.

How Is Excimer Laser Treatment Performed?

Excimer laser treatment works by reshaping the cornea. The procedure is planned to correct your refractive error and is customized to the structure of each patient’s eye.

The treatment proceeds as follows:

  1. Preparing the Eye Surface: Before treatment, the eye is numbed with drops and the cornea is prepared.
  2. Laser Application: The excimer laser sends precise pulses to specific areas of the cornea to reshape it.
  3. Correcting the Refractive Error: The laser allows light to focus correctly on the retina, with the aim of correcting problems such as myopia, hyperopia and astigmatism.

During excimer laser treatment, the aim is to support clear vision safely, without harming the healthy tissue of the eye. The procedure is usually short and is performed by an ophthalmologist.

When Is the Excimer Laser Used?

Excimer laser treatment is an effective option for people who do not want to wear glasses or contact lenses and who have a suitable corneal structure.
It is commonly used for the following refractive errors:

  • Myopia, or nearsightedness (blurry distance vision)
  • Hyperopia, or farsightedness (difficulty seeing up close)
  • Astigmatism (blurred or wavy vision)

This treatment is recommended only after the structure of your eye has been assessed in detail. The excimer laser reshapes the cornea in the targeted area so that light focuses correctly on the retina. This sharpens vision and can reduce the need for glasses in daily life.

Is Excimer Laser Treatment Safe?

Excimer laser treatment is a well-established method that has been used for many years and is supported by advanced technology. It works by making precise changes only in the targeted layer of the cornea and is designed to leave the surrounding healthy tissue unaffected.

When your eyes are found suitable for treatment and the procedure is performed by an experienced ophthalmologist, refractive errors can be corrected safely with the excimer laser. Regular follow-up visits and following your doctor’s advice throughout the process contribute to a good outcome.

Benefits of Excimer Laser Treatment

Excimer laser treatment is an advanced laser technology used to correct refractive errors. In people with suitable eyes, it can help achieve clear natural vision.

Its main advantages are:

  • A quick return to daily life
  • Less dependence on glasses or contact lenses
  • Treatment that can be shaped to the individual eye
  • Precise treatment with advanced laser technology

The excimer laser is a reliable method that has been used for many years to treat refractive errors such as myopia, hyperopia and astigmatism.

Recovery After Excimer Laser Treatment

Excimer laser treatment is performed under local anesthesia (numbing eye drops), and recovery is usually quick. When it is used as a surface treatment (PRK or TransPRK), no incision is made in the cornea, and with either approach many people can return to daily life within a short time.

Some points to keep in mind after treatment:

  • Avoid rubbing your eyes
  • Keep using your drops for as long as you have been told to
  • Limit screen time in the first days if needed
  • Attend the follow-up visits your ophthalmologist recommends

Recovery varies from person to person, but most people can return to their daily activities within a few days. In suitable patients, excimer laser treatment can improve visual comfort and support quality of life.

Excimer Laser Treatment: Information and Planning

The details of excimer laser treatment and how it is planned are assessed individually. The cost of treatment can vary depending on the technology used, the method planned for your eye and the facilities of the healthcare provider.

To get detailed information about the excimer laser and determine the most suitable approach for you, it is advisable to consult an ophthalmologist.
A specialist assessment is an important step, both for accurate information and for making a sound decision.

Why a Specialist Assessment Matters Before Excimer Laser Treatment

Before excimer laser treatment is planned, a detailed assessment by an ophthalmologist is necessary. This assessment is important to determine whether the treatment suits the structure of your eyes and your visual needs.

Before starting treatment, asking your doctor for a personal pre-examination is the right first step toward a safe and effective outcome. If you are found suitable, the excimer laser may improve the quality of your vision.

Why Choose Excimer Laser Treatment?

Excimer laser treatment is an advanced, precise procedure for correcting refractive errors. It can help reduce the need for glasses or contact lenses, particularly in myopia, hyperopia and astigmatism.

Planned individually, this method reshapes the cornea so that light focuses correctly on the retina. The aim of treatment is to help you achieve clear, good-quality vision. With its often quick recovery and the support of modern technology, excimer laser treatment stands out as a reliable option for people who want more comfort in daily life.


By helping correct refractive errors such as myopia, hyperopia and astigmatism, excimer laser treatment can reduce the need for glasses or contact lenses and improve visual comfort.
