Because the lasering is done on  the eyeball itself, it’s described as “in situ,” or “on site.” Its complete name is “laser in-situ  keratomileusis” – but you probably know it as LASIK.
Weil man direkt am Augapfel lasert, nennt man das "in situ", also "vor Ort". Der volle Name lautet "Laser-in-situ-Keratomileusis" -- vermutlich besser bekannt als LASIK.
