One of the aftereffects of the procedure is

that as the gas/fluid interface moves, I now have a line across the (blurry still)vision in that eye.  Which is now across the upper field of view. 

Which means that when I walk that line has a wave pattern moving back & forth across it(jiggles a bit with heartbeats, soo).  As Og put it, my eye is now a damned bubble level.
