Many highly myopic patients, especially those with more than 800 degrees of myopia, are always overwhelmed by the choice of myopia surgery. Here are some relevant explanations. 1, for more than 1200 degrees of myopia patients, the ideal means of removal is ICL implantation, definitely not LASIK, EK and other corneal refractive surgery, forced to do corneal refractive surgery, there is a risk of secondary cone corneal resulting in corneal transplantation, in addition, easy to refractive regression. If the doctor does not tell these patients “you should do ICL implantation, not keratomileusis”, then it is recommended that you transfer to a more responsible hospital for consultation. 2. Patients between 800 and 1200 degrees can have either LASIK or ICL implantation, depending on the patient’s choice, if all conditions allow. This range of degrees can be flexible according to the patient’s choice and eye conditions; in foreign countries, doctors recommend ICL implantation for myopic patients with more than 800 degrees, because it is relatively safer. 3, for patients with less than 800 degrees of myopia, it is still recommended to do keratoconus surgery, although the ICL correction range is large, from 300 degrees to 2000 degrees of myopia can be, but after all, the price is twice the traditional keratoconus surgery. In terms of efficacy, there is little difference between the two methods in this degree range, and the same flexibility is available according to patient requirements and eye conditions. However, if the thinness of the cornea does not allow for corneal laser surgery, then ICL implantation should still be chosen.
