LASIK and LASEK – What you should know

With the term refractive surgery, we describe the interventions that help us get rid of the myopia, hyperopia and astigmatism. These operating procedures, aim to reduce our dependence on glasses and contact lenses – and the problems these have probably caused.

THE OPERATION-What is the difference betweem  LASIK, LASEK and

The transparent front outside wall of the eye is called Cornea, following the white of the eye. In both cases, a crust on the cornea is temporarily formed (called “flap”) under which it, the laser will be applied and then the flap is going to be repositioned. While in the LASIK flap is thicker in LASEK it is very thin, consisting only of the surface layer of cells. In LASIK thus the laser is applied in deeper layers of the cornea. With LASIK larger degrees of myopia can be corrected, it is painless and vision stabilizes rapidly. The LASEK method (or Epi-LASIK which is similar) is preferred when the cornea is thin and not quite normal, the eyes are drier, the degrees are low, and for people that are more likely to be injured in the eye once, for reasons of occupation or hobby. This is a more advanced form of the PRK method  (historically the first technique, for laser myopia correction), without the postoperative pain.

The flap is formed Sculturing with Laser The flap is repositioned

Once the laser is applied, the flap is repositioned over the rest of the cornea, which has the ability to hold the flap without sutures.
