How Lasik Works

LASIK Surgery in Cincinnati

LASIK or Laser in-Situ Keratomileusis corrects vision by reshaping the corneal tissue beneath the surface of the cornea rather than on the surface. LASIK combines the accuracy of the Excimer laser with the healing benefits of a surgical procedure called Lamellar Keratoplasty, performed on a limited basis since 1949, to treat higher levels of nearsightedness and moderate amounts of farsightedness . The Tri-State Centers For Sight pioneered LASIK surgery in Cincinnati, Ohio.

After the eye has been completely numbed using "eye drop" anesthesia, an eyelid holder is placed between the lids to prevent blinking. Next, an instrument called 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. The cornea is made flatter to treat nearsightedness, steeper to treat farsightedness and more spherical to treat astigmatism . Next, the protective flap is folded back in place where it bonds without the need for stitches.

Because LASIK is performed under a protective layer of tissue, there is less surface area to heal, less risk of corneal haze, less postoperative discomfort, less need for postoperative medication and vision returns more rapidly, often within a day or two. LASIK can also treat a higher range of nearsightedness, farsightedness and astigmatism.
