Ophthalmology
Laser Assisted In-Situ Keratomileusis (LASIK): The surgeon uses a
microkeratome to cut a flap of the corneal tissue (usually with a thickness of 100-180 micrometres). The flap is lifted like a hinged door, but in contrast to ALK, the targeted tissue is removed from the corneal stroma with an excimer laser. The flap is subsequently replaced.
