LASER EYE SURGERY WITH

PRK / LASEK

PRK (lat. photorefractive keratectomy) or LASEK is a proven treatment method of refractive surgery for the correction of nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. In contrast to Femto-LASIK, no corneal flap is generated, rather the top layer of the cornea is carefully removed. This method can therefore also be used to treat patients with particularly thin corneas. However, the healing time with PRK/ LASEK is longer than with Femto-LASIK because the top layer of the eye has to grow back.

Difference between PRK & LASEK

Fundamentally, the two abbreviations PRK and LASEK describe the same treatment idea. The two methods differ only in the way the top layer of the cornea (the epithelium) is removed. The treatment of the visual problem with the excimer laser is the same.

PRK
lat. Photo­refrak­tive Kera­tektomie
LASEK
lat. Laser Epi­thelial Kerato­mileusis
Trans-PRK
lat. Trans­epi­theli­ale Photo­refrak­tive Kera­tek­tomie
Conventional
The uppermost corneal layer is carefully removed mechanically.
Advanced
The top corneal layer is carefully removed with an alcohol solution.
High-precision
The top corneal layer is removed with high precision by the laser.

 

Advantages of the Trans-PRK

The Trans-PRK is a further development of the PRK and is much gentler because the eye has no contact with any mechanical instruments. Instead, the top corneal layer—which is not suitable for laser eye surgery— is removed using the latest laser technology. This is a minimally invasive procedure without contact. This makes the Trans-PRK particularly gentle and precise and is therefore also suitable for patients with a particularly thin cornea.

The advantages of the Trans-PRK
  • No direct contact: without prodding and without an incision
  • Very few complications and minimal risk of infection
  • Fast recovery through the protection of the tissue
  • Less pain after the procedure compared to traditional PRK
  • The surgery only lasts a few minutes
Lasermed Standard: Wavefront Optimization

In addition to nearsightedness, farsightedness and astigmatism, your eye may also have other small optical aberrations. These are due to small deviations in the cornea and/or the lens. They can influence the result of the PRK and are determined by a Wavefront Analysis during the pre-examination at the eye center.

With the Wavefront Analysis, a light is sent to the eye where we will measure how the light re-emerges from the eye again. Ideally, this will result in an error-free Wavefront. If this is not the case, the corresponding deviations can be taken into account with the Wavefront Optimization—an additional function of the laser.

The result of laser eye surgery becomes even more precise with a Wavefront Optimization. With this, risks for side effects such as glare sensitivity and halos can be avoided and vision during twilight hours can be improved. Wavefront Optimization is particularly advantageous for those with relatively large pupils.

At Lasermed, the Wavefront Optimization is used as a standard in all laser eye procedures. In this way, we can guarantee an even higher quality of treatment and satisfaction.

PRK

The Procedure

After you have decided on PRK (lat. photorefractive keratectomy) or LASEK in a free, initial consultation, and your eyes have been examined and measured in the subsequent preliminary examination, you will receive an appointment for your laser eye surgery. On the day of the procedure, our experienced team of optometrists and doctors will assist and accompany you safely at every step along the way.

Laser Eye Surgery

  • Before the actual laser eye surgery takes place, your eyes are anaesthetized with a gel so that the treatment is completely painless.
  • The top epithelial layer is then carefully removed. This is only done on the surface that is actually lasered.
  • Then the excimer laser is used, which performs the actual correction of your vision problem—this process takes only a few seconds and is completely painless.
  • In the days following the surgery, the corneal layer grows back on its own. Until then, your vision will be blurry.
The preliminary examination
The measurement of your eyes
  • Once you have decided to undergo laser eye surgery with PRK/LASEK after the first free consultation, you will make an appointment for a preliminary examination.
  • You should not wear soft contact lenses for two weeks and hard contact lenses for four weeks before the preliminary examination in order to guarantee correct measurements.
  • In the preliminary examination, your eyes will be measured again accurately and comprehensively by one of our qualified optometrists. Your eyes will then be examined again by an ophthalmologist and you will be informed about the risks and side effects.
  • You can expect the following measurements in the preliminary examination:
    • Determination of eye length
    • Measurement of anterior chamber depth
    • Measurement of pupil width
    • Determination of your refractive values in diopters and additional subjective adjustments
    • Control of the anterior and posterior segments of the eye
    • Eye pressure control
Costs of the preliminary examination
  • The preliminary examination is a medical service in which the billing is pre-determined by law. However, the costs of the preliminary examination are included in the surgery costs. Should you later decide against PRK/LASEK, the costs of the preliminary examination must nevertheless be paid. These costs are usually not covered by health insurance companies.
Before surgery
What you need to keep in mind
  • You should be accompanied on the day of your PRK surgery/LASEK eye surgery, as you are not allowed to actively participate in traffic After the PRK/ LASEK procedure, your eyes are blindfolded with an opaque bandage and a transparent bandage. This means that your vision will be restricted.
  • Do not wear make-up, perfume or hairspray on the day of the surgery.
  • Feel free to eat and drink normally before the surgery.
The preparation
  • You will first be given a light sedative so that you can start your life free of glasses without anxiety or fear. Your eyes will then be numbed with a gel. Laser eye surgery is therefore completely painless.
  • You lie down on the surgical chair. The eye laser is above your head and the ophthalmologist is sitting at the direction of your A small clamp keeps your eye open, so you don’t have to worry about accidentally blinking.
More details about PRK surgery/ LASEK eye surgery
Laser eye surgery
  • In PRK/LASEK, the top layer of the cornea (the epithelium) is first removed. This layer grows back on its own during recovery and is therefore not suitable for lasering.
  • Your eye is then lasered with the excimer laser and your eye condition is corrected by changing the surface of your eye. This takes only 2-3 seconds per diopter. The actual laser eye surgery is over so quickly that you hardly notice it.
  • During the surgery, you will focus on a small light above you to keep your eye in the correct position. You can’t do anything wrong here. The laser has what is known as eye tracking, through which it automatically follows even involuntary eye movements. If the movements become too strong, the laser automatically stops within milliseconds. There is no risk that the laser can “slip”.
Directly after laser eye surgery
  • Directly after PRK surgery/ LASEK eye surgery, you cannot see sharply. It will seem as if you are looking through frosted glass.
  • For protection, your still very sensitive eyes are blindfolded. You won’t be able to see anything and will be taken home by the person accompanying you. Don’t worry—you will find the darkness of the bandages comfortable.
  • In the following days, you will take eye drops as an aftercare measure according to a prescribed eye drop schedule that prevents inflammation. Stick to the schedule as it will eliminate the biggest risks and complications associated with laser eye surgery.
  • Since the top layer of your cornea must grow back on its own, the healing time after PRK/LASEK is usually painful in the first 24 hours after the procedure. For this, you will need to take a painkiller and will notice your vision improving day by day.
After the surgery
The time after PRK / LASEK eye surgery
  • You will have aftercare follow-up appointments at intervals of 1 day, 1 week, 1 month and 1 year. In this way, we can ensure that the healing time for your eye is optimal.
  • Your vision will improve day by day. Typically, you will have achieved your full visual acuity after 1–2 weeks. However, this varies from patient to patient.
  • In the weeks after laser eye surgery, you may still be sensitive to light and have dry eyes. Sunglasses and eye drops will help get through the healing time, so that you can enjoy your life without glasses very quickly.

Lasermed FAQ

Frequently asked questions

What is a PRK surgery?

A PRK (lat. photorefractive keratectomy) or LASEK (lat. laser epithelial keratomileusis) eye surgery is a proven treatment method of refractive surgery. The uppermost layer of the cornea (the epithelium) is carefully removed. The surface of the cornea is then corrected so that the light from the eye is refracted correctly and you can see sharply without glasses.

How does a PRK eye surgery work?

In PRK eye surgery, the uppermost layer of the cornea (the epithelium) is first carefully removed. This is either done manually or by a laser. The underlying layer of the cornea is then corrected by the excimer laser so that the light from the eye is refracted optically correct again. A PRK surgery allows you to see sharply without glasses.

PRK surgery vs LASIK, which is better?

In general, there is no better or worse to the PRK surgery vs LASIK question. It depends rather on the individual condition of your eye in determining which method is more suitable for you personally. We will be happy to advise you on this personally in a free, initial consultation.
However, a PRK/LASEK eye surgery is generally better suited for patients with particularly thin corneas. If you play a contact sport or work for the police, fire department or military, Femto-LASIK is not recommended due to the creation of the flap. Femto-LASIK, on the other hand, is a gentler surgery and you are able to see sharply again much faster.

What are the advantages / disadvantages of PRK?

Patients with a thinner cornea can also be treated with PRK surgery. In addition, the surgery is particularly suitable for patients who play contact sports or work for the police or fire department, for example. The healing time after PRK eye surgery lasts just as long as after a Femto-LASIK surgery. A PRK is known to be safer. However, after PRK , it takes a few days longer until you can see sharply again. Moreover, the recovery on the first day is somewhat painful, since the uppermost corneal layer (the epithelium) must grow back. For these side effects, you will of course get painkillers.

Why is my vision blurry after a PRK eye surgery?

In the first days following your laser eye surgery with PRK surgery/ LASEK eye surgery, your vision will be blurry because the upper corneal layer of the eye (the epithelium) needs to grow back. Blurred vision is therefore perfectly normal and no cause for concern. Directly after the laser procedure, the eye is incomplete—so to speak—in a way that it seems as if you are looking through frosted glass. This veil, however, becomes noticeably fainter from day to day and you begin to see sharper and sharper. After a few days, you can see well again. After two weeks, you have usually reached full visual acuity.

When can I see sharply again after a PRK eye surgery?
Experience has shown us that after a few days you can see well again, even if it is not completely sharp. This is because the top layer of the eye needs a few days to regenerate. You will notice a gradual improvement from day to day and can see relatively sharp after two weeks.
How long is the healing time with PRK eye surgery?

Experience shows us that the healing time after PRK surgery or LASEK eye surgery takes two weeks. After just a few days, however, you will be able to see relatively clear again. The eye heals completely after about four weeks. During this period, the recovery process is monitored by regular, aftercare follow-up examinations.

When can I exercise or play sports again after PRK?

Usually, you can exercise and play sports again two weeks after a PRK eye surgery. Until then, you should give your eyes time to heal and avoid getting sweat or dirt into your eyes by taking a break from sports. For contact sports, you should wait longer. The treating doctor will discuss this with you personally.

When can I drive again after a PRK eye surgery?

You can usually drive again two weeks after a PRK eye surgery. This can vary from person to person but will be determined in the follow-up appointments. You will receive a certificate that you are fit to drive without visual aids.

How painful is a PRK eye surgery?

Before your eyes are lasered, you will receive anesthetic eye drops so that the surgery is completely painless. In PRK surgery, the top layer of the cornea (the epithelium) is removed and must grow back in the following days. Therefore, the healing time is somewhat painful, especially on the first day after the surgery. As an aftercare treatment, however, the pain can be alleviated with eye drops and medication.

How long will I see halos after a PRK/ LASEK eye surgery?

Halos are small rings of light that can be visible side effects of a PRK surgery – coming from light sources such as streetlamps. However, not every patient experiences halos due to PRK. If they do indeed show up, they usually disappear quickly in the first weeks after the surgery.

How long do I need to take eye drops after PRK?
Following PRK, you will need to apply eye drops several times a day for several weeks. The eye drops help the eye to heal and prevent infections. After the laser treatment, you will receive an eye drop schedule which will outline the intervals and periods for applying aftercare eye drops. If you stick to the schedule, you can’t do anything wrong and will avoid complications.
When can I wear make-up again after PRK?

In order to prevent dirt or make-up particles from getting into your recovering eye, you should refrain from wearing any make-up two weeks after PRK eye surgery. Make-up and make-up removal inevitably lead to small bits of make-up getting into your eye, which increase the risk of infection. After two weeks, you can wear make-up again as usual.

How many diopters are treated with PRK eye surgery?

With PRK surgery, we correct nearsightedness up to -4 diopters, farsightedness up to +2 diopters and astigmatism up to +6 diopters. According to Commission for Refractive Surgery (in German, Kommission für Refraktive Chirurgie—KRC) guidelines, values up to -8, +3 and +6 diopters can be corrected with PRK. At Lasermed, however, we only treat visual disorders according to our own pre-determined limits. This is due to the fact that, according to our own experience, the risk of side effects—which can lead to dissatisfaction and lower quality—increases with values higher than our pre-determined limits. For higher values, there are alternative treatment methods which, in our experience, are medically more sound. We would be happy to advise you personally in a free, initial consultation.

When should I stop wearing contact lenses before the PRK eye surgery?

You should generally not wear contact lenses a few days before a PRK surgery. However, this will be discussed again at the appropriate time with the treating doctor. You should refrain from wearing contact lenses a little longer before the preliminary examination: two weeks for soft contact lenses and four weeks for hard contact lenses.
