It is true that corneal transplantation is a thing since decades. However, a corneal transplant, like any transplant, has its issues. Rejections can still occur, and the healing process takes a long time, usually not less than one year, involving constant adjustments. If a cost-effective synthetic inert material addresses these issues, this is immense progress.

But the GGP says

>>> How long have we been waiting for some way to regrow the tooth after a cavity?

An artificial cornea probably solves a lot of problem with rejections, but it is somewhat like filing the cavities in the teeth with whatever paste they are using.

I've read about people getting cataract surgery and ending up with UV sensitivity due to the material some older synthetic implants were made from, so I always assumed artificial corneas weren't uncommon.[1] I've actually kind of hoped I could get them some day.

Is the difference here that previous implants weren't total replacements, or something else?
