Laser eye surgery is becoming a popular method for correcting visual impairments such as myopia, hyperopia and astigmatism. There are various different procedures available and LASIK, or laser-assisted in situ keratomileusis, is probably the most common. What does it involve and what are the benefits of this surgical procedure? LASIK involves the use of a microkeratome or femtosecond laser which cuts a flap in the cornea. This flap is pulled back to reveal the stroma layer. Employing an excimer laser which uses ultraviolet light beams to remove minute amounts of the underlying corneal tissue, the cornea is reshaped to properly focus light onto the retina in order to improve vision. Once completed, the flap is put back in place and the cornea is left to heal naturally.
