However, if economic conditions permit, it is recommended not to cut the cornea to do ICL, which is especially suitable for myopic friends with high degree and thin cornea. Moreover, the operation is reversible. If the degree changes, just replace the intraocular lens. Laser myopia surgery needs to cut the cornea, which not only requires the corneal thickness, but also can not be operated again after the degree changes. My friend is studying in Germany. He said that laser myopia surgery has basically stopped in Europe because the long-term effect of the surgery is unknown and the risk is high. You can keep asking me questions. I hope my answer is useful to you.
