So you know you want to improve your vision and you’ve heard about LASIK surgery, but what is really involved?
Answer: LASIK surgery reshapes the cornea (the clear covering in the front of the eye) to actually change the way the eye focuses light. The goal is to reduce your need for corrective lenses.
LASIK involves a few steps. First, your surgeon will create a thin flap of corneal tissue about 100 microns thick, which is roughly the same thickness as one and a half human hairs. He will then move the flap out of the way and use a laser to reshape the cornea by removing small amounts of tissue. The flap will then be repositioned over the treatment area like a bandage. By only removing tissue underneath the LASIK flap, the eye is fooled into not knowing it had surgery and the wound response is muted. This is why there is quick vision recovery and little discomfort. Most patients experience improved vision immediately with virtually no pain.
Of course as with all surgery there is risk, although the vast majority of people who have LASIK are satisfied with the results. Millions worldwide have had LASIK or similar laser vision correction surgery.
