I don't know how it compares, but my dad had cataract surgery. The prep time (vitals, sedation) was longer than the actual procedure. The process itself took all of about 15 minutes.
He went from wearing tri-focals to just needing reading glasses. He should have had it done years earlier.
I was not sedated in any way. They offered it as an option, but I declined; I dislike the feeling of being drugged.
