LASIK uses an excimer laser (an ultraviolet laser) to remove a thin layer of corneal tissue. This gives the cornea a new shape so that light rays are focused clearly on the retina. LASIK causes the cornea to be thinner. 

The surgery is minimally invasive and requires no incisions on your body. Once you are asleep, a small lighted instrument (ureteroscope) is placed into your urethra and bladder to access your ureter and kidney. Once the stone is seen, a laser fiber is used to transmit Holmium energy to break up your kidney stones.
