TransPRK 7D smart surFace State-of-the-art surface treatment

At least twelve months before the procedure (ideally even longer), the visual defect should not have changed.
Healthy eyes are also essential.
Diseases such as cataracts or retinal conditions simply do not allow treatment with Trans-PRK.
In the case of long-sightedness, a value of plus 3 is the maximum up to which the procedure can be carried out; in the case of short-sightedness, the permitted value is minus 8. Astigmatism can be treated with Trans-PRK up to a value of 6 dioptres.
However, one thing should be clear: Which method is best for a patient is determined solely by the doctor.
The doctor knows the patient and, above all, knows the eye that needs to be treated.
Accordingly, it is not always the diopter values alone that make the difference.

Of course, this is usually easier said than done – after all, it is an intervention directly in the eye.
However, trans-PRK is a method that does not require any touching.
Why is that?
Well, more modern laser technology is actually inconceivable than that used in trans-PRK, which eliminates the need for a classic operation such as conventional PRK, where the operating doctor still has to remove the epithelium (the corneal flap that is folded over) by hand.
Because the excimer laser can perform this detachment much more precisely, there is no pain involved.
In addition, the wound healing process is much faster.
Healing usually does not take longer than three days.
Once the epithelium has been removed, the actual correction begins – which is also done quite simply by laser.
This works on the uppermost layer of the cornea and thus eliminates the defective vision in the eye.
That’s all it’s really about.
To protect the cornea, relieve pain and accelerate wound healing, the doctors place a special contact lens over it for the first few days.
This allows the cornea to recover quickly without disturbance or external influences.

Trans-PRK is the most modern development of all surface treatments.
It is ideally suited for all initial surface treatments.
However, if it is a resurfacing procedure, PRK would be preferred.
Patients who are active martial artists or exposed to potential trauma would be very good candidates for all resurfacing treatments.
In this case, there are no weak points in the cut lenticule that could be displaced by force.
Patients with a thin, slightly irregular cornea are also good candidates for this type of treatment.
Patients who frequently choose this type of treatment belong to the following professional groups: Martial artists, police officers and soldiers.

How safe is the Trans-PRK?

very safe.
Anyone who undergoes this procedure need have no concerns.
Why is this the case?
Well, the epithelium grows back so quickly that hardly any complications can arise.
This also means that vision is restored within a very short time, significantly faster than with conventional PRK or LASEK (toxic effect of alcohol).
Nevertheless, it takes a few weeks for vision to recover.
In a few cases, treated patients complain that the healing process is sometimes somewhat painful, and some patients also experience slight corneal clouding/scarring (haze).
This usually causes a temporary deterioration in vision.
Eye drops help in the short term, and this clouding, also known as haze, is not permanent either.
It is essential for all patients to attend the follow-up appointments scheduled by the ophthalmologist after the operation.

How safe is PRK?

The superficial cells are removed using a mechanical instrument.
First, however, the cells are soaked in alcohol, which also has a toxic effect.
This is also the reason for the prolonged wound healing compared to trans-PRK.
The epithelium grows back together within 3-7 days.
This also means that vision is restored within 1 week, albeit somewhat more slowly than with trans-PRK.

How safe is LASEK?

The superficial cells are removed using a mechanical instrument.
The removed epithelial area is often larger than the required “laser zone diameter”.
This is also the reason for the prolonged wound healing compared to trans-PRK.
The epithelium grows back together within 3-7 days.
This also means that vision is restored within 1 week, although somewhat more slowly than with trans-PRK, where only the necessary epithelial surface is removed with the laser.

The term Trans-PRK stands for “Transepithial Photorefractive Keratectomy”.
In practical terms, this is an advancement of the LASEK and PRK methods used to treat the corneal surface.
While PRK used to be the standard procedure for laser eye surgery, LASIK has replaced it – LASIK is simply associated with less pain.
However, LASIK has failed in those patients whose cornea is simply too thin or irregularly structured in the eye.
However, the modern possibilities offered by trans-PRK have made a decisive contribution to optimizing the procedure.
In principle, however, this only applies to patients with short-sightedness or astigmatism.
If farsightedness is present, Trans-PRK can only be performed successfully if the diopter values are reasonably low.

The results after TransPRK are very predictable.
They are identical to the results of other laser eye surgery methods.
However, it takes a little longer to achieve full vision (3-4 months).

The tried and tested laser eye treatment: the LASEK / PRK laser eye method Photorefractive keratectomy, or PRK for short, is a surgical procedure that has been performed since 1987 and is therefore one of the oldest methods of refractive laser surgery.
In PRK / LASEK / Epi-LASIK treatment, the uppermost cell layer of the cornea (the epithelium) is removed and the corneal tissue immediately underneath is optimally shaped using the excimer laser.
The difference between the PRK, LASEK and Epi-LASIK methods is the way in which the epithelium is removed:

• PRK: The epithelium is completely removed, which is why an alcoholic solution is applied to the cornea for 30 seconds in the first surgical step.
• LASEK: The epithelium is pushed aside before the laser treatment.
  After the eyes have been lasered, an attempt is then made to push the epithelium back again, but this is often no longer possible.
• Epi-LASIK: The epithelial cells are separated from the lower surface using a mechanical microscalpel (microkeratome) in order to push them back again after the laser procedure.
• Trans-PRK/ No-Touch-PRK: In non-touch surgery, the epithelium is removed by the excimer laser beam before the actual correction.
  The lack of contact minimizes the risk of infection.

In contrast to LASIK and Femto-LASIK, these methods are superficial laser operations.
The postoperative course is painful in the first few days and full vision is achieved more slowly.
This surgical technique is therefore only used if LASIK or Femto-LASIK is not an option.
Immediately after the operation, you will notice that you can see more clearly due to the strong tear film, but you should keep your eyes closed for the rest of the day if possible.
You can find out more about preparation and aftercare for your laser eye surgery under Treatment.
After Trans-PRK / PRK / LASEK / Epi-LASIK, you may experience severe pain for the first 2 to 3 days while the cells regenerate, as the top layer of the cornea has been removed.
However, this can be alleviated with painkillers.
The quality of vision may fluctuate in the first weeks to months.

We first disinfect your facial area.
You will be given a local anesthetic in the form of eye drops.
Your eyelids will be fixed in place.
All of this is absolutely painless and painless.
You will be asked to keep the green light fixed above you throughout the operation.

In the first step, the uppermost cell layer of the cornea, the epithelium, is detached and removed (see above).
In contrast, in the newer LASIK or Femto-LASIK method, the corneal flap with the epithelium is only folded back.

The extremely fine laser beam then removes a thin layer of the central cornea.
This creates a new corneal surface.
The laser shapes and models the existing corneal tissue in such a way that defective vision and astigmatism are corrected.
You will not notice any of this either, apart from the sound of the laser and possibly the smell of the cornea.
The surgeon controls the use of the laser.

In the final step, soft bandage contact lenses are inserted to protect the eye after the operation.
Drug treatment prevents inflammation and reduces post-operative pain.
The protective lenses are removed after 2 to 4 days.
That’s it!
