Re: Breaking physics
"Holy cow! I couldn't imagine anything worse than the Microtome used during LASIK until I read the description (and saw photos) of a Vitrectomy. I hope you were asleep."
Dunno about Dave, but during mine (as part of a retinal reattachment) I was quite happily wide awake (aside from the area around my right eye, that was well and truly under the control of whatever local anesthetic they use for this sort of procedure) and thoroughly enjoying every fascinating minute of it all - as someone with the typically inquisitive mind of an engineer, being able to experience something like that first hand was pretty amazing.
Especially since, being rather terrified of needles, there's probably no way in hell I'd be able to watch such a procedure in the third party, but when it's your own eye that's being worked on, the needles are conveniently out of sight... The follow up caratact removal op and laser clean up procedures a couple of years later were almost as much fun too.
And on a more practical note, the surgeon who did my original op did say they prefer if if people are able to go through the procedure with just local anaesthetic, as it makes the post-op recovery process easier when patients aren't needing to be brought back around from being under.
