The one disadvantage to this procedure is the fact that the results don’t last that long. Eye surgeons are aware of this and tend to ‘over-correct’ your eyes: by this we mean that he/she will compensate for this regression by correcting your eyes more than they need to.
This over-correction may mean that you have some degree of short-sightedness. You may have to wear glasses or contact lenses for the first few weeks as a result of this.
You will find that your vision will start to regress in the first 2 to 3 months following surgery, and then, at a much slower rate over the next couple of years.
However, some studies have shown that the effects can last much longer than that. In some cases they can last for 5 even 10 years.
But, this is still seen as a temporary procedure only.
