Blind from what? The only gear related issue is increased blood pressure causing excess pressure on the eyes - as long as your BP is in check, you should be fine, but if you want to tell the doc, tell him, but don't expect an eye surgeon to know shit about gear.
I had the surgery twice (the 2nd time was an enhancement, I had particularly bad eyes). But I was not on at the time. It was well worth it.
You do need to plan for a week off from lifting. Maybe the guy that went blind went and did 700lbs deads the same day and blew out the flap...
