Implanting a lens from a deceased young person causes cloudiness (cataract) within days due to lens protein leakage when the capsule is violated.

“if you violate that capsule of the lens the lens immediately becomes cloudy so here's an example let's say that you talked about trauma so a typical scenario is uh somebody is uh working with a weed eater or whatever a weed whacker yeah and and a piece of a shard of rock or glass or something goes through the cornea and embeds itself in the lens and it might even be an optically unimportant part of the lens maybe it's off to the side but once that capsule has been pierced inevitably lens protein starts leaking out inflammatory cells become you violated the privileged site it's no longer privileged and within days you start to see a cataract”
