Things to know before getting LASIK Surgery:

Lasik, it's a genius idea who's premise comes from knowing that the cornea has the most refractive power in the eye system.  If you change the shape of the cornea, then you will manipulate or in this case, drastically improve the patient's eyeglasses prescription.  

Lets talk about expectations.  Expectations should be to lower your dependency on glasses, not to eliminate the eyeglasses.  If someone is telling you to get LASIK Vision Correction to eliminate wearing eyeglasses, beware because it isn't true.  I feel much more comfortable with more reasonable expectations than to say glasses will be eliminated completely.
A drawback to LASIK vision correction is the annoying glare when looking at lights night.  This occurs because of the  flap that is created when pealing back the front layer of the cornea to expose the part that will be reshaped with the laser. 

Will you wear glasses again after LASIK? Yes.  The corneal cells regenerate every 24 hours which is the reason our prescriptions change so much in certain times of our lives.  Prescriptions stabilize, but they change nonetheless.  And if that doesn't get you, presbyopia will.  Changing the shape of the cornea solves the prescription of the day.  Once the cells regenerate and the accumulation of that rate of change influences the change of eyeglasses prescription.

Eyeglasses, you're going to wear them. You'll always need them. Keep that in mind before you get LASIK Vision Correction.
Some people end up with 20/20 vision. Some people end up with 20/15, which is even better than 20/20.  Others end up with 20/30 or 20/40 that is just the way things go.  It is a statistical probability you can never predict how well you're prescription is going to be after you get it done. It is refreshing to know that a majority of people have a good experience.  Go see your optometrist, go see your ophthalmologist and they can help you determine if you are a good candidate for LASIK Vision Correction Eye Surgery.
