Significantly improve self-confidence and lifestyle, PRK can also be used to correct problematic visual defects. Enjoy your life carefree, without contact lenses or glasses.
The first laser eye treatment in humans was photorefractive keratectomy (PRK) with the excimer laser. It was first carried out in 1987 and is therefore considered the first generation of laser eye surgery. In this laser procedure, the corneal epithelium is first removed either mechanically with a scalpel, with alcohol, a microkeratome or a laser. Subsequently, the underlying upper cornea is modeled with an excimer laser. After lasering, a bandage must be worn for a few days until the epithelium has regenerated. In the PRK eye laser method, the uppermost corneal surface, the epithelium (regenerative top corneal surface), is separated from the rest of the cornea with a special spatula. Therefore, the PRK method is also referred to as the surface method.
After the epithelium on the corneal surface has been separated, the refractive error is corrected with an excimer laser. The nearsightedness and / or the corneal curvature are corrected in such a way that the light force is then optimally adjusted.
Once the light force has been optimally adjusted again, patients can enjoy life again without glasses and contact lenses.
After the PRK laser eye treatment, the epithelium must regrow at the point where it was removed. In order to protect or stabilize this area (wound), patients must wear soft bandage contact lenses for about 3 – 5 days after PRK surgery.
The pain after a surface laser eye treatment such as PRK and LASEK are the same. The intensity and duration of pain are significantly higher in relation to LASIK or femto-LASIK surgery!
Even if the pain is subjectively different for each patient, patients should expect pain until the soft bandage contact lenses are removed. In particular, the first 36 hours are very unpleasant. For this reason, it is best for patients to treat themselves to a lot of bed rest for 3 days after PRK treatment.
The operation takes about 30 minutes and is performed on an outpatient basis. If you have any further questions, just give us a call. We would be happy to answer further questions.
