At present, there are two popular methods of laser eye surgery - Lasik and Lasek. The most commonly used form of laser eye treatment is Lasik. In Lasik, a small incision is made in the cornea to create a flap. Laser treatment can then be carried out. There may be vision loss of 20 to 30 seconds during the procedure. In Lasek the epithelium is removed before the cornea is reshaped with a laser. Laser eye treatment takes around 15 minutes in total.
