My dad had this done and his knees don’t hurt from gout anymore. His diet changed dramatically too. Zero meats. It’s been a while so I am allowed this one gag about my dad! He was such a great guy and I miss him very much. IE he is D I D dead, so he is in a sense vegan like myself.

All seriousness aside, he did get detached retinas and the vitrious liquid in his eyeball replaced. We could see the bubble and his eyes changed from brown to green. My coworker too had a lens op where they also replaced the stuff in the eye.
