1995,

LAL has been around for tens of thousands, perhaps more, in the US, and many, many more than that in Europe where they have been implanted for about 15 years. Did you read somewhere that very few people had these implanted?

I've not read much about bifocal IOLs, but many, many multifocal have been implanted - maybe millions? They have their own issues - lots of online reading is available.

Monovision - millions have this, both with IOLs and from LASIK and PRK. Again, millions of folks have this construct. Lots of reading available online.
