Comment Re:Effective cataract eye drops are already availa (Score 4, Informative) 70
N-acetyl carnosine drops have been used with good success for a while. Bought them for my grandmother in law. Over the course of a couple of years it halted and mostly reversed her developing cataracts. Can get them from multiple sources.
Good information - especially while we're waiting for this stuff to become available.
I note, though, that:
- This newly-identified material substantially clears cataracts in six days while N-acetyl carnosine takes four months for significant improvement to show.
- This newly-identintified material appears to be what the eye normally uses in a specific mechanism to prevent/repair cataracts, while N-acetyl carnosine appears to have more generic antioxidant and chelation properties. (It's a modification of carnosine to a form which can penetrate the tissues of the eye and is converted back to carnosine within them. Carnosine is great for retarding several ageing mechanisms but it looks more like a generic helper than a specific repair-mechanism component or trigger for cataracts.)
- The discovery of this new stuff occurred by identifying what was missing in people with a genetic early-cataract problem. If this is necessary for cataract prevention/repair and its production declines (but doesn't fully stop) with age, N-acetyl carnosine might not work for people who don't make it at all.
So though N-acetyl carnosine looks good, this looks great and specific. (And I don't see any reason to stop the former even if taking the latter. Unless some specific interaction issue shows up I'd expect them to work well together.)
