How long dose Lasik results last, Is it permanent?
Generally, the Lasik good vision results can last 15 - 20 years and until you
are 40 years old for most patients. A small percentage of patients will have
some decrease in the effect over many years, but in most cases the remaining
vision is still very good.
The most important factors for the last time
of Lasik vision results is stable to start with. The Lasik has changed the
shape of your cornea below the surface, in the stable layer called the
stroma. If the eyeball has a fully mature of Lasik, the laser reshaping of
the cornea's curvature is permanent. From this point, you should not have
vision results change.
However, corneal shape is not the only factor that can impair vision. There
are many causes of defective vision besides the shape of the cornea. The
most common reason is the Presbyopia. The Presbyopia is an age-related
condition that happens to everybody. When we reach about 40 years old, the
lens becomes less able to change its curvature and becomes increasingly
fixed in a relatively flat shape. Your near vision is now blurry even if you
had Lasik as a young person and get a good visual results.
There are other eye conditions that impair eyesight, such as cataracts ,
macular degeneration , and glaucoma , and they may happen regardless of
whether you had LASIK.
