No. Some people are surprised to learn that conventional LASIK is only partly performed by a laser. The first step in conventional LASIK uses a metal blade, called a microkeratome, and a mechanical holding device to create a corneal flap. The second step is performed by an excimer laser to reshape the cornea.LASIK replaces the blade in the first step of the procedure with a computer-controlled cold-beam laser. This treatment is 100% All-Laser and 100% blade-free, providing patients with a safer, more precise approach to laser vision correction.
