Yesterday afternoon I had the PRK Laser Vision Correction surgery. I was pretty stressed out beforehand, and took the Valium they offered me to calm my nerves. I’m glad I did. It was a little odd having several people all poking and prodding at your open eyeballs under the laser. The procedure took maybe five or six minutes. The PRK surgery differs from LASIK in that rather than creating a flap on the outer cornea layer, they chemically (or mechanically) remove that outer layer.
