The person is usually awake throughout the procedure; he may nonetheless be given a sedative. The first incision is used a microkeratome or a femtosecond laser and a flap of the cornea at the assigned area is cut. In doing so, the flap LASIK Eye Surgery Dallas is folded up back to reveal the stroma, which is the mid-section of the cornea. Next an excimer laser is utilized to straighten the stroma.

The degree of precision is often times sharper than that provided by lenses and even standard LASIK.
