How does laser eye treatment work?

Either a femtosecond laser or an excimer laser is used for laser eye surgery for non-contact trans-PRK.


With Femto-Lasik, a high-precision femtosecond laser creates an ultra-thin corneal lamella (flap) that is folded upwards like a book cover.

The excimer laser then shapes the cornea and thereby corrects the existing visual impairment. The flap is folded back and connects firmly with the tissue within a few weeks.

The advantages of Femto-Lasik

  • High precision
  • Gentle and almost painless
  • Quick visual rehabilitation
  • Even, thin, smooth corneal flaps
  • Tissue-conserving corneal ablation
  • Quick and straightforward wound healing
  • Generally full vision the next day

Contact-free Trans-PRK

In contact-free Trans-PRK, the excimer laser is used to remove the outer layer of the cornea (epithelium). By dispensing with mechanical instruments, this revolutionary treatment method is especially precise and gentle on tissue. Contact-free Trans-PRK is especially suited to patients with a thin cornea who, for this reason, do not meet the conditions for other treatments.

The advantages of Trans-PRK

  • Contact-free treatment
  • Fewer complications
  • Cheaper method of laser treatment
  • Ideal for athletes and active people
  • Suited to patients with a thin cornea
