Clear Vision without Glasses or Contacts, in 15 Minutes
What is LASIK Surgery?
LASIK is the most common and well-known vision correction surgery, and is used to treat nearsightedness, farsightedness and astigmatism. LASIK (laser-assisted in situ keratomileusis) is performed while you recline under an excimer laser in an outpatient surgical center. With an experienced surgeon, LASIK takes only 10 to 15 minutes.
The eye is numbed with a local anesthetic. Your surgeon uses a laser to reshape the cornea (the clear, round dome at the front of the eye) to improve the way the eye focuses light rays onto the retina. The surgeon creates a thin flap over the outer layer of the cornea, then the laser is used to reshape the cornea to the correct shape. The flap is then placed back over the eye, and it heals in place.
For people who are nearsighted, LASIK is used to flatten a cornea that is too steep. Farsighted people will have LASIK to achieve a steeper cornea. LASIK can also correct astigmatism by shaping an irregular cornea into a more normal shape.
What to Expect?
Many patients report greatly improved vision the day after undergoing refractive surgery LASIK, but it is important to have realistic long-term expectations. Most people are able to perform many everyday tasks without wearing glasses or contact lenses. However, your vision may not be “perfect,” particularly if you need extremely precise vision on your job or to perform certain tasks. Nine out of ten people who have LASIK achieve somewhere between 20/20 and 20/40 vision without glasses or contact lenses. This is very good vision, but it may not be 100 percent satisfactory for every individual.
