900 degrees of myopia belongs to high myopia, like this degree of myopia, if surgical treatment, the first choice should be corneal refractive surgery, that is, excimer laser surgery, femtosecond laser surgery. The cost of excimer laser surgery is about 5,000-8,000 yuan; femtosecond laser is about 8,000-18,000 yuan. Because the full femtosecond laser is about 18,000 yuan; the price of the semi-femtosecond laser is 8,000-12,000 yuan. Of course, in addition to corneal refractive surgery, you can also choose intraocular refractive surgery, which is an IOL implantation for crystalline eyes. The cost of this surgery is relatively higher and normally costs about 20,000-30,000 yuan, mainly because the IOL implanted in the surgery is more expensive.
