Special advantages of PRK

Refractive Laser Correction started in 1990 with Photorefractive Keratectomy, abbreviated as PRK. In a surgical procedure using an Excimerlaser the surface of the central cornea is being altered to a flattened shape for people who are myopic and a more curved surface for people who are hyperopic.

  • PRK is the oldest method of eye laser treatments.
  • Suitable for patients with a thin cornea.
  • The Trans-PRK is the latest generation of surface treatments.

The individual steps of PRK, Trans-PRK, LASEK

Step 1

The upper corneal layer is removed (PRK) or pushed to the side (LASEK).

Step 2

With the PRK/ Trans-PRK/ LASEK, an excimer laser forms the corneal tissue within seconds to compensate your ametropia.

Step 3

After the treatment, a contact lens is placed on the cornea until the top layer of the cornea has formed again within the next few days.

What are the advantages and disadvantages of PRK/ Trans-PRK/ LASEK?

„We determine which procedure is actually suitable for you through thorough preliminary examinations.“

Dr. Gero Krommes

The superficial layer of the cornea (epithelium) is removed and the cornea is lasered to compensate your ametropia.

In contrast to the LASIK method, no corneal flap is produced. However, a wound surface develops which can lead to discomfort or pain. In the time after the operation, the epithelium must grow together again.

In order to remove the uppermost layer of the cornea, a solution of diluted alcohol is applied to the cornea. The epithelium is removed with a manual surgical instrument (PRK), pushed to the side (LASEK) or removed with a laser (Trans-PRK/Smart Surf).

Now an excimer laser forms the corneal tissue within seconds to compensate the defective vision.

After the procedure, a bandage contact lens is placed on the cornea until the top layer of the cornea has formed again within the next few days.

The healing process is significantly longer compared to LASIK or SMILE. If the defective vision is greater, the risk of scarring and sensitivity to glare is higher than with LASIK or SMILE.
