Lasek laser or Epilasik surgery is a variation of the two previous techniques (PRK and Lasik).
The ophthalmologist makes an incision with a sharp blade on the external membrane of the cornea (epithelium) that he pulls down in one layer after having softened it with alcohol. The laser beam is then directed towards underlying tissues as in the case of PRK. At the end of the surgery, the epithelium is put back in place.
The Lasek is recommended for visual problems correction (average myopia). The recovery process lasts approximately a week.
The Lasek or Epilasik surgery technique has the same risks as PRK (pain, eye blurring during the first days). However, with this technique, the pain during the first days is sometimes less strong.
