Just be prepared for the waiver you have to sign.

After all of the advertising about how amazing and safe and wonderful it is, the rubber meets the road with the release you sign.

Essentially “we’re about to shoot LASERS into your eye and if we manage to not BLIND you, that’s a good outcome.”

All routine, of course, but it’s still a scary form to sign.

Indeed. They also don't seem to let you schedule each eye separately. Maybe they will if you complain enough, or are willing to pay more.
