What is TransPRK?

TransPRK is a type of laser vision treatment. The method is a further development of PRK and is an especially good alternative for people with thin corneas who are not suitable for Femto LASIK. TransPRK is particularly effective for the treatment of short-sightedness and corneal curvature. Correction of long-sightedness is also possible with low dioptre values.

Quite simple

TransPRK in four steps

Your laser eye treatment at betterview has four simple steps:

Preliminary examination

During a 30-minute, no-obligation, free initial consultation on site, we find out whether you can have laser vision correction and which treatment method is best for you. In particular, we have a look at your cornea, eye lenses and corrective devices.


Main examination

The main examination takes about 45 minutes and is also free of charge and with no obligation to purchase.

Firstly, we anaesthetise your eyes with drops. During TransPRK, our doctors ablate the uppermost corneal layer of the eye (epithelium) using state-of-the-art laser technology. The laser then corrects the refractive error. The procedure takes less than 15 minutes for both eyes.

The epithelium grows back within three days. To examine the healing of your eyes and the progress of your visual acuity in detail, we do a first follow-up five days after the procedure.

Frequently asked questions about TransPRK

These are the most important and frequent questions and answers about betterview. If you can't find the answer to your question here, please get in touch with us.

Which method is better, TransPRK or Femto LASIK?

Femto LASIK is the most commonly used laser eye treatment method. It is completely pain-free; the healing process is extremely short, and we can achieve full vision by the very next day. With TransPRK, the healing process takes somewhat longer—we therefore use it 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 TransPRK?

After TransPRK, you have to wait 4–6 weeks until your eyes are completely healed, and you have full vision. However, about 5 days after the procedure, most clients are ready to return to work and drive.

How long do the TransPRK results last?

The TransPRK results last a lifetime. However, please note that the treatment does not protect against the development of further refractive errors. Presbyopia in particular, starting around the age of 45, can make visual aids necessary again. Alternatively, we can permanently correct it with a refractive lens exchange.

What are the procedure's undesired effects?

TransPRK is considered an exceedingly safe laser treatment, with very few side effects such as light sensitivity, watery, red or gritty eyes. In the first few days after treatment, vision may be blurred and vary somewhat. Slight pain, which we can treat well with eye drops, may also occur in the lasered eye.

How much does TransPRK cost?

TransPRK procedure costs differ based on the provider. betterview charges 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 TransPRK and PRK?

TransPRK is a further development of PRK. The most significant difference is that TransPRK 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.
