LASIK is a surgery that uses a laser to reshape the cornea of the eye. This reshaping changes focusing power and usually corrects vision. Surgery may be done on both eyes, either at the same time or on separate occasions.
LASIK is done to reduce the need for glasses or contact lenses.
Most people who get LASIK will still need reading glasses at middle age and beyond to correct for
(decreased ability to focus due to age).
Be sure to discuss presbyopia with your doctor prior to getting LASIK so that you understand how it will affect your vision.
You will be positioned on your back in a reclining chair. The eyelid will be held open with a special device. A ring will be placed on the eye and pressure is applied to create suction. A blade will then be attached to the suction ring. The blade will be used to cut a flap in the cornea. The flap will be folded back.
You will look into a light (not the laser). A laser will be directed to remove a specific amount of corneal tissue. The laser will make a ticking sound as it reshapes the cornea. At this point, some patients report a smell similar to burning hair. When the laser is finished, the corneal flap will be gently placed back into position. Antibiotic drops will be put in the eye. A shield will be placed over the eye.
There are other ways to do laser vision correction surgery. One includes using a laser to make the flap in the cornea. The other includes removing the top layer of the cornea with a special device or chemical, then using the laser. Ask your doctor which procedure is best for you.
You will likely feel some discomfort when the suction ring is applied. Just after the procedure, expect a burning or itching sensation or the feeling that there is a foreign object in your eye. Your eye may tear and be red and bloodshot. You will most likely have a loss of vision at times during the procedure. This is normal.
