Maybe, maybe not.

Here’s the link to the PubMed abstract:

Title:  Efficacy of N-acetylcarnosine in the treatment of cataracts

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&...
=Abstract&list_uids=12001824&itool=iconabstr

With the BIG caveat that this is the only medical citation, the study
was small and provided by and funded by the manufacturer.

Perhaps there is something to it, but for now, I go with, as you wrote,
unproven, quack remedy.

There is also Vitreolent (Novartis AG Pharma, Germany/Poland
distribution). It is a potassium iodide drop that was prescribed
following the Chernobal nuclear catastrophy and since. I have two
patients using that medication and have no idea if their cataracts would
be worse without.

Further, back when I was in school, a R&D pharm company in Connecticut
was working on a N-acetylcarnosine and ascorbic acid sub-conja implant
dispensing device that showed pretty decent efficacy, at least in dogs.
Shortly after they published preliminary findings, the company, and the
report disappeared.
