Here in Brazil we have a kind of honey named "Mel de Jataí" that folk people believe to cure cataract. I have been using it in my eyes and feel a great improvement. It is necessary to use one drop a day in each eye for two months and the cataract will vanish. I was diagnosed with cataract a few months ago. You may research for a correspondent honey in English. I think it is worth trying.
EC: Here's an excerpt on Honey Jatai from Brazil that we found online.
..."The honey of jataí bees is sought after for its medicinal properties and immunological, anti-inflammatory, analgesic, sedative, expectorant, desensitizing and antibacterial effects. It is also effective for swollen eyes and treatment of cataracts."
