I suspect you experience true blindness (briefly) during laser eye surgery, when the flap is cut in the cornea. I remember how odd it felt - the feeling of seeing nothing at all, not even darkness.
- DigitalJack 12y agoI could see after the flap was lifted. This was 2005 so I don't know the procedure anymore, but I was supposed to keep my eye trained on a flashing dot while the laser ablated my cornea.
- gd1 12y agoI meant when the blade goes into the eye. There were a few seconds after that before vision came back.

"you have to pump the pressure up in the eye to about 6x normal in order to cut a good flap, as you can't cut an accurate flap in a floppy eye. The pressure is actually higher than your blood pressure, so the eye stops perfusing with blood, and you go temporarily blind."
