If you considere laser eye treatment, you should be aware of some important facts about lasik.

Fact 1 : Laser eye treatment is not for everyone.  It sounds like the answer for anyone who wears glasses or contacts, but you have to be absolutely certain that this procedure is what you want.
Fact 2 : find the best board-certified ophthalmologic surgeon in your area and familiarize yourself with his or her credentials and experience.  Lasik is a procedure that must be taken seriously.  Determine whether he or she will continue as your physician after surgery, or if you will be referred to someone else.
Fact 3: lasik is primarily recommended for people with near-sightedness, or myopia, and for astigmatism.  The degree of refraction is important in that severe myopia may require repeat procedures.
Fact 4 : people with a history of dry eye, disease of the cornea, or other eye conditions should not consider lasik.
Fact 5 : since laser eye treatment surgery is performed while the patient is awake, the physician should explain the procedure to you before the operation.
Fact 6 : post-operative care is very important in lasik.  The use of eye drops, as prescribed, must be followed exactly in order for the cornea to heal properly.
Fact 7 : don’t expect miracles.  Some patients find their vision is corrected to 20/20 or 20/40, but others may not.  There is no guarantee what the end results may be.
Fact 8 : presbyopia or far-sightedness that occurs in middle-aged patients is not correctible with lasik.  Reading glasses will still be needed.
 

How does LASIK work and are there needles involved?
Vision is corrected by reshaping the inner corneal bed of the eye. This is done by removing a very thin layer of tissue from the front surface of the eye called the cornea - placing the lens power of your glasses on the cornea. Persons being treated remain remarkably comfortable though the entire procedure, requiring only a few anesthetic drops in the eye to ensure a virtually pain-free procedure that takes only minutes. No needles are used and with current technology there is very little discomfort after the procedure. A more detailed explanation (complete with pictures).

How much time will I have to be off work?
That depends on whether you have your eyes done one at a time or both together. You would have to be professionally examined to determine what is best for you. In any case, most people return to work and other normal activities within 3 - 7 days. This period may be longer if you develop any complications or if you have a medium to high initial correction (-5.00 diopters or above).
