My right eye vision acuity is worse than my left eye. i had lasik when i was 18 12 years ago and had 20/20. i need glasses now apparently, and my right eye is way more blurry than my left. what caused this? can i get lasik again?

Do you need glasses for distance or reading? You've become either nearsighted if distant objects are blurry or farsighted if nearby ones are blurry. Your lens have changed curvature. Most surgeons won't perform a second lasik procedure for at least 5 or even 10 years after the first as the cornea may be too thin. An ophthalmologist can answer your question best.

The curvature of your cornea has changed. See a LASIK specialist for evaluation of your corneal thickness as well as the curvature of the front and back surfaces of your cornea. It may be safe to get a simple LASIK enhancement; however, your doctor must rule out ectasia or forme fruste keratoconus, both of which are serious and may require a corneal crosslinking procedure.
