Laser vision correction
is to use a laser knife to cut the cornea (transparent tissue with a thickness of about 0.5 to 1.0 mm on the surface of the black eye) around 3/4 of the circle, lift up the upper cornea, and then remove a portion of the lower corneal tissue with a laser knife. The upper cornea is covered back to correct myopia.
