LASIK corrects nearsightedness, farsightedness, and astigmatism. You could be one of the 1.5 million Americans expected to undergo LASIK this year. In fact, LASIK has become the most popular elective surgery in the country. In order for the eye to focus light clearly on the retina, the cornea (outer window of the eye), must be of the proper curvature. Using a “cool” light beam from the Excimer laser, very minute quantities of corneal tissue are removed, predictably altering the shape of the cornea and in turn correcting the refractive error.
The Tri-State Centers for Sight pioneered LASIK surgery in Cincinnati and continue to use the most advanced techniques available in corrective surgery to achieve optimum vision. For the past 28 years, the Tri-State Centers For Sight have achieved the highest level of patient care, as our doctors provide personalized attention to each patient before, during and after surgery. Our experienced team of doctors can help change the way you see the world.
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.
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.
Bladeless LASIK technology
In the past, the corneal flap was created by a mechanical device, which used a blade (microkeratome). Today, we offer our patients ALL LASER LASIK using the Ziemer FEMTO LDV™ Femtosecond Laser to create the corneal flap, thereby adding a higher level of safety and precision to the LASIK procedure. Using this , the Femtosecond laser delivers over millions of tiny, micron-sized bubbles that gently separate the layers of corneal tissue. This creates a customized corneal flap of the desired thickness, size, orientation, and location. This unprecedented level of control also allows more patients to qualify for LASIK and virtually eliminates many of the complications associated with the past mechanical approach.
