They charge a lot of money, and they usually treat some difficult patients. They are very confident. Amblyopia treatment is known as the first-class level in China, and it takes effect faster in them. It really takes some effort.
My child's optic atrophy was treated with them for two courses (30 days) at a cost of 7600 yuan. The vision of one eye is improved by 3 lines, and that of the other eye by 2 lines. I think it's worthwhile.
