LASIK

LASIK is the most frequently used method for correcting visual defects today.

The LASIK (laser in situ keratomileusis) correction was first performed in the USA in 1991. It offers the advantages of a safe surgical method and rapid recovery time following the intervention, connected with unique comfort for the patient. Since its introduction in the 1990s, it has been applied millions of times around the world and has been continuously further developed and standardised during this time. The LASIK correction has been scientifically tested and recognised in Germany and the USA.

The LASIK intervention

The whole intervention takes place using anaesthetic eye drops and lasts about ten minutes per eye. First of all, a thin flap of corneal tissue is prepared using an automatic microkeratome (miniature blade). During this time, the eye is temporarily fixed using a suction ring, which is felt as slight pressure on the eye. Next, the thin corneal flap is folded out of the way leaving just a narrow “hinge”.

Excimer-Laser does the correction

The desired change of shape is sculpted on the underlying corneal layer using the excimer laser. This ablation of tissue with the laser takes between 30 and 90 seconds. In this process the smallest, unintentional eye movements are also registered by the laser and automatically corrected.

Then the corneal flap is flipped back into its original position and bonds itself naturally to the surface below. Further fixation is unnecessary. Slightly hazy vision and watering of the eye may occur after the intervention. After just a few hours, sufficient visual acuity is achieved so that you no longer require glasses or contact lenses. Your newly achieved vision stabilises after four to eight weeks.

Why LASIK?

  • LASIK leads to extremely accurate and safe results.
  • The procedure only lasts a few minutes, is painless and is carried out as an out-patient.
  • The recovery period after the procedure is painless, except for a temporary foreign body sensation and an increase in tears. 
  • The sight’s recovery period is very short as the corneal flap protects the surgical wound like a plaster produced naturally by the body and therefore sight can rapidly normalise itself.
  • You can already pursue your usual activities a few days after the procedure.
  • Sight is stable after approx. 4–8 weeks.

Excimer laser

LASIK is carried out using an excimer laser. This laser is a cold laser that can ablate corneal tissue precisely without causing shrinkage or disturbing scarring of the surrounding tissue.
