Refractive surgery is a surgical method to change the refractive state, mainly divided into corneal refractive surgery and intraocular refractive surgery, patients with 1500 degrees of myopia, can not do corneal refractive surgery, can do intraocular refractive surgery, as follows: 1, can not do corneal refractive surgery: in corneal refractive surgery, the general plate of the degree of surgery does not exceed 1200 degrees, SMILE surgery surgery does not exceed 1000 degrees. The surface layer surgery may generally not exceed 800 degrees, 1500 degrees of myopia is very high, so the corneal surgery may not be very suitable. 2, can do intraocular refractive surgery: patients can consider intraocular refractive surgery, intraocular refractive surgery is more recommended for crystalline eye IOL implantation, similar to the implantation of a contact lens into the eye, positioned behind the iris, before the lens, the degree of correction is higher, so this This surgery is an option to consider for very high levels of myopia.
