Laser-Assisted in Situ Keratomileusis (LASIK) means modifying the shape of the cornea by using a laser. A precise instrument called a microkeratome is used to remove a thin layer from the surface of the cornea, except for a small part of it that keeps it attached to the eye and is moved back. The inner corneal tissue (estimated according to the type and degree of the visual defect) and then, the surface layer of the cornea is returned to its normal position to fuse without the need for any surgical stitches.
