Hi there Terry.
I am not going to to give you a load of "this can happen" stories, but I suggest that you check out
www.lasikdisaster.com
As a side note between myself and Fee we do not know of any optometrists or doctors (including opthalmologists) that have elected to have this surgery, and we do have close friends and colleagues with a range of refractive errors from about +6.00 through to about -9.00
If you do choose to go ahead with this sugery pop down to your local LASIK clinic for a free assesment and ask the surgeon if he/she will be performiing the surgery and if they or anybody in the clinic has been zapped.
The very best of luck to you if you do choose to have this surgery.
