You're assuming that losing a $10,000 bet is the same as experiencing some side affects years after having Lasik. It's not that clear-cut - you don't go blind. A fairer comparison might be a $10,000 bet only paying out $9,000, but while you play you get free drinks and a show, so maybe the trade-off is worth it.

I had Lasik about ten years ago. I just didn't like the inconvenience of glasses and contacts and taking them on/off all day when switching from a screen to driving/walking and back was straining.

I went in understanding that there was a risk night vision degradation in the future. But really, I'd likely have experienced that with age anyway.

To this day LASIK is the best money I've ever spent. I've got near-perfect vision and have since taken up many activities (flying, cycling, motorcycling) that, while they can be done with glasses, are much, much more convenient without them.
