Would it be possible to apply a UV absorbing coating to the artificial lenses, or would that mess with the optics and/or durability?

There doesn't need to be a coating, you can get artificial lenses that don't allow UV light through.

Based on this link, UV absorbing intraocular lenses have been around since the ‘80s, but not all of them are very effective, and they’re not universally used. Based on a little reading, it’s unclear what makes it difficult, but my guess is that it’s hard to exclusively block UV light without affecting the tint and clarity of the lens.

I imagine many UV absorbing compounds also degrade from the absorption.

Very true as well, that’s a big reason why our natural lenses degrade over time.
