The many different types of lasik eye surgery vary in price and quality.  Some are cheaper than others.  The entire operation averages around $1,500 to $2,500 per eye for traditional lasik and as high as $3,000 to $4,000 for more advanced methods requiring more sophisticated operations and lasers alike. 
One of these lasik variation operations is known as wavefront lasik.  It has the ability to correct your vision to full restoration.  Some patients experience better than 20/20 vision after the operation.  Some report 20/40.  Some, however, will not be good candidates for this type of vision correction.  However, most people will benefit with laser vision correction.
Wavefront lasik eye surgery has been used since 2002 on the international stage in medical circles. It is much different from the regular lasik procedure. It's also a fairly quick procedure. Wavefront lasers provides the surgeon a more accurate view of the interior and exterior eye region on a microscopic level through the generation of 3-D imaging computer systems.  Every single operation is tailored specifically for each patient waiting since the computer imaging charts a different detailed eye scale for each. The eye surgeon conducting the operation can then correct any refractory errors in the eye more accurately giving better results.  Side effects may result but are minimized with this type of laser vision correction operation.  This is why wavefront is so costly.  
If you want to consider this type of operation to get 20/20 or better vision, then check with your local eye doctor for references and recommendations on lasik surgery.  Be sure to do your research first to the pros and cons of vision correction.
