Established procedureSurface treatment
Surface treatment
(PRK / Trans-PRK)
Laser procedure for correcting certain refractive errors – ideal for thin corneas and for active people.
During surface treatment, the top layer of cells of the cornea is removed. The excimer laser then reshapes the cornea precisely to correct refractive errors. The cornea regenerates on its own over the following days.

Procedure steps
1Removing the top cell layer
The top layer of the cornea is gently removed.

The excimer laser reshapes the cornea according to the refractive error.
3Healing of the surface
The cornea regenerates on its own over the following days.
Healing & recovery
The first few days may involve a foreign-body sensation and light sensitivity. Visual acuity stabilises gradually within the first few weeks.

Frequently asked questions
Does the treatment hurt?
Vor der Behandlung wird das Auge mit Augentropfen örtlich betäubt. Während des Eingriffs werden daher in der Regel keine oder nur geringe Beschwerden wahrgenommen. In den ersten Tagen danach können jedoch Schmerzen, Brennen, Fremdkörpergefühl und Lichtempfindlichkeit auftreten. Die individuelle Nachsorge und Schmerzbehandlung erfolgt durch die behandelnde Klinik.
How long does healing take?
The top layer of the cornea regenerates within the first few days after the treatment. Visual acuity may fluctuate at first and stabilises gradually. How quickly recovery progresses varies individually and is assessed during follow-up examinations.
When can I return to work?
Depending on the healing process and your occupation, a break from work of several days may be necessary. Screen-based work in particular can be more demanding at first. When you can resume your professional activity should be agreed individually with the treating clinic.
Who is surface treatment not suitable for?
Not every patient is suitable for PRK or Trans-PRK. Certain conditions or irregularities of the cornea and ocular surface, as well as other individual factors, may speak against treatment. Whether the procedure is medically suitable can only be assessed after a thorough ophthalmological pre-examination.
How permanent is the result?
The change to the cornea made by the laser is permanent. Nevertheless, visual strength and vision can change over the course of life. In individual cases, a new spectacle correction or further treatment may become necessary.
When can I do sport again?
When sporting activities can be resumed depends on the healing process and the sport in question. Contact with the body, water, dust or an increased risk of injury may require a longer break. The treating clinic will give you individual recommendations on this.
