Epitelcellene (det gjennomsiktige hudlagt yterst på øyet) fjernes først ved hjelp av en fin børste. Laseren endre deretter formen på den gjenværende horhinneoverflaten. Man kan si at ASA er en todelt operasjon. Først børster man bort det ytterste cellelaget også utføres selve laserbehandlingen som fjerner nærsynthet, langsynthet og/eller skjev hornhinne.

    After ASA it is permanently removed. It will grow back again very nicely.

  • The laser treatment is preformed on the cornea. In a one step, no-touch, all-laser prosess the laser first removes the epithelium, which is the outermost region of the cornea. Then in the same treatment the laser removes some of the stroma (which is the next layer of the cornea). The tissue is permanently removed, but the epithelium will grow back after 2-3 days

  • Is the tissue permanenty removed? Or is it replaced?
