What is LASIK?

LASIK surgery is about a 15-20 minute in-office procedure performed at Crews LASIK & Cataract Center and has been successfully treating patients in Vancouver, Washington; and Portland & Central Oregon for many years. LASIK, or Laser-Assisted In-Situ Keratomileusis, is an FDA-approved refractive procedure that is performed on nearly 1 million patients each year.

LASIK surgery corrects nearsightedness (myopia), farsightedness (hyperopia), and astigmatism by permanently changing the shape of the cornea, increasing focusing power and improving vision. In LASIK surgery, precise and controlled removal of corneal tissue by a special laser reshapes the cornea changing its focusing power. LASIK surgery is one of the most common vision correction procedures. It is designed to reduce your dependency on glasses and contact lenses.

What Happens During LASIK Surgery?

After your eye has been completely numbed using “eye drop” anesthesia, an eyelid holder will be placed between your eyelids to prevent you from blinking. Next, an instrument known as a microkeratome makes a protective flap in the cornea. During this process you may feel a little pressure but no discomfort. You will be asked to look directly at a target light while the laser reshapes the cornea, usually in less than a minute.

The Excimer laser removes microscopic layers of corneal tissue to change its shape, allowing light rays to focus more directly on the retina. Then, the protective flap is folded back in place where it bonds securely without the need for stitches. After LASIK, some patients report a slight discomfort that usually goes away within twelve to twenty-four hours.
