I recommend Shenzhen Eye Hospital. I did it there in the summer of 2000. At that time, my eyes were almost 900 degrees, which cost about 8000 yuan (including some examination fees). Compared with other hospitals, it is a little expensive, but the effect is not bad. At least they are specialized hospitals. Don't make fun of their eyes. My friend made it last year, and the price dropped by about 6000.
