What Happens During ALK Eye Surgery?
ALK, performed under local anesthesia, usually takes less than an hour to complete. A cutting device is used to make a small incomplete flap across the cornea. While still attached at one side, the corneal flap is folded back to reveal the layer of tissue below. Another, very precise cut is made on the sub layer of tissue based on the person’s eyeglass prescription. After this cut, the corneal flap is placed back over the eye where it reattaches.
