Lasik can be used to correct refractive lens problem such as short sightedness, long sightedness and astigmatism. These refraction problems occur when the images that are formed by the natural lens of the eyes on the retina are not sharp. The focal length is not right, and just like a camera, if the focus is not good, the images are blurry. Lasik uses very precise lasers to target certain tissues in the eyes to correct refractive defects.

Before Lasik is conducted, there are some safety precautions to be taken. You will likely be asked to take antibiotics for up to two weeks to prevent unnecessary infection during the procedure. The doctor will also do a thorough examination of your eyes to determine if the eye has just common refractive problems, and not other kinds of eye problems. Your refractive problem should also have stabilized in the last 12 months or so, else the procedure may not correct your vision accurately.

The process is quite straightforward. First, the doctor will lift a thin layer from the top of the cornea. Then he uses a suitable laser to etch away parts of the cornea to correct for refractive problems. How much is etched depends on how severe your short sightedness or long sightedness problem is. If it is astigmatism, Lasik will etch away parts of the cornea to create a more uniform curvature in the lens. At the end of the procedure, the cover of the cornea is put back in its original place.
