I love my Lasik eyes but-
Some nearsighted eyes repaired by Lasik are slightly more prone to tearing or even detachment of the retina. Yearly Eye exams may provide early detection of tearing or "holes" that can be repaired with an Argon Laser. Left undetected the retina may become detached and that requires an involved reattachment operation.
Occasional jagged floaters or flashing lights in the eye are a probable warning sign of this condition.
I know this now - because last Friday the "holes" in my right retina were repaired. Tomorrow I go to the hospital for the eye surgery to reattach my retina on my left eye. It's not a 100 percent sure thing repair either so not catching this problem earlier may cost me in vision acuity and not to mention a serious loss of beer money.
