Back to 100% vision with No-Touch-PRK

What is Trans-PRK?

Trans-PRK is a type of laser vision treatment. The method is a further development of PRK and is especially a good alternative for people with thin corneas who are not eligible for treatment with Femto-LASIK. Trans-PRK is particularly suitable for the treatment of myopia and astigmatism. Correction of hypermetropia is also possible with low diopter values.

Quite simply

Preliminary exam

In a free and non-binding preliminary examination, we determine whether and which laser eye treatment is suitable for you. In particular, we take a look at your cornea, eye lenses and corrective devices. The preliminary exam takes about 30 minutes.


Primary Exam

The primary exam takes about 45 minutes and is also free of charge with no obligation.



First, your eyes will be treated with numbing drops In trans-PRK, the uppermost corneal layer of the eye (epithelium) is ablated using state-of-the-art laser technology. The correction of the refractive error can then be performed, also by laser. The procedure takes less than 15 minutes for both eyes.


Follow-up Visits

The epithelium grows back within three days. In order to examine the healing of your eyes and the progress of your visual acuity in detail, a first follow-up visit will take place after five days.

What you need

Am I a good candidate for laser eye surgery with Trans-PRK?

  • Shortsightedness, astigmatism or slight farsightedness

The advantages of the Trans-PRK


100% Vision

In most cases, 100% vision can be achieved. If full vision is not achieved, laser treatment can usually be repeated in a second treatment..



Your eyes will be treated exclusively with the laser. The Trans-PRK is thus completely contact-free, which enables the highest precision and safety.


Alternative to Femto-LASIK

Femto-LASIK is the most commonly used laser method. However, it is not suitable especially for thin corneas and high ametropia - trans-PRK is an excellent alternative.


Short treatment period

The actual correction with the laser takes only a few seconds per eye. After about 15 minutes, the treatment is already completed on both eyes.


Maximum safety

Trans-PRK is performed using the latest laser technology. The eye tracker automatically switches off the laser at the slightest eye movement.


Also for dry eyes

Trans-PRK is considered to be an exceedingly safe laser treatment, with very few side effects. It is also particularly gentle for dry eyes.

Frequently asked questions about Trans-PRK

Here you can find the most important questions and answers about betterview. If your question cannot be answered here, please feel free to contact us.

Which is best, Trans-PRK or Femto-LASIK?

Femto-LASIK is the most commonly used eye laser method. It is completely painless, the healing time is extremely short and full vision is achieved the very next day. With Trans-PRK, the healing process takes somewhat longer - it is therefore used in particular as an alternative to Femto-LASIK, for example in cases of thin corneas and high ametropia.

When will I be able to see clearly after trans-PRK?

After a laser eye treatment by means of Trans-PRK you have to expect 4-6 weeks until your eyes are completely healed and the full visual performance is achieved. However, about 5 days after the procedure, most of those treated are ready to return to work and can drive again.

How long do Trans-PRK results last?

The results of laser vision correction with Trans-PRK last for a lifetime. However, it should be noted that the treatment does not protect against the development of further refractive errors. Presbyopia in particular, which begins around the age of 45, can make a visual aid necessary again or, alternatively, be permanently corrected with a refractive lens fitting.

What side effects can occur?

Trans-PRK is considered an exceedingly safe laser treatment, with very few side effects such as light sensitivity, watery and red eyes, and a gritty feeling. In the first few days after treatment, vision may vary slightly and be blurred. Slight pain may also occur in the treated eye, but this can be treated well with eye drops.

What does the Trans-PKR procedure cost?

The cost of laser vision correction with trans-PRK varies depending on the provider. At betterview the procedure costs CHF 1,490 – per eye. This fixed price includes all costs including a 3-year warranty. The preliminary and main examinations at betterview are free of charge and without obligation - you only pay if you actually decide to undergo the treatment.

What is the difference between trans-PRK and PRK?

The Trans-PRK is a further development of the PRK. The biggest difference is that trans-PRK is performed with no contact at all - only the laser works on the cornea. It is therefore also referred to as No-Touch PRK. In classic PRK, on the other hand, the top layer of the cornea is not removed automatically with the laser, but manually.
