That means they inject anaesthetic using a needle around the back of the eye. (The needle prob. goes through the cheek, just below the eye ball, past the equator of the eyeball, and around the back of your eye socket).
This paralises the optic nerve which controls all your vision, as well sections of the tri-geminal nerve, which controls your eye movements (they also tie all your muscles down, so that they can 'move' your eye during operation).
Don't worry.. this sort of surgery may need you to be under general anaesthetic, so you won't know a thing anyway.... if it's done under local.. then don't worry, coz you won't feel or see a single thing while it's being done.
Means that they would use anaesthetic to completely dim your vision.
Good luck
