Eye clinics here do not even want to talk eye drops or anything else for a mild cataract, that can be cured if you believe those who use other than waiting for surgery, without asking a doctor.
How is that global when ex. in Germany, there may be alternatives, but for what I do not know.
In China, they have acupuncture and herbs we can order, but they also use surgery we can read.
So how are your neighboring countries and further afield?
