*(it was so bad they could only guesstimate;BTW legal blindness is 20/1000 per the doctor)
Quite surprised you were even considered a candidate for LASIK with 20-900 vision!
I was that extremely nearsighted also, and the radial keratotomy my eye surgeon did 15 years ago gave me perfect vision.
To me, it’s a miracle. I’m still thrilled to wake up in the dark, and be able to see the time without hunting up my glasses. Goodbye contact lenses, glasses, prescription sunglasses, reading glasses, solution, etc. etc.
I had PRK in 2007. The difference is instead of slicing a "flap" on the eye, they scrape and laser the surface. My doctor used "bandage contacts" to protect the eye during healing.
My vision improved from 20/800 to 20/15. I've heard one person complain that their vision deteriorated back to pre-op condition.
I've got no problems with haloing. The only problem I've experienced is my preexisting light sensitivity is aggravated.
