High myopia can be repaired by surgery, but surgery cannot reduce the risk of high myopia itself, which can easily complicate other eye diseases. High myopia is not an absolute contraindication to myopia surgery. The ability to have myopia surgery and the type of myopia surgery depends not only on the degree of the eye, but also on the corneal thickness, corneal curvature, and corneal endothelial count. Corneal refractive surgery is one of the more mature and effective ways to treat myopia. It changes the refractive power of the cornea by precisely cutting the corneal tissue, which in turn changes the refractive state of the whole eye, making the patient less dependent on glasses after surgery and achieving the effect of treating myopia. However, since the surgery is performed on the cornea, patients need to have good corneal conditions. Generally, the higher the degree of myopia, the more cornea is cut, which means patients need thicker corneas. Therefore patients with high myopia need to have more cornea removed compared to patients with low myopia. For patients with myopia above 1200 degrees, the predictability of keratoconus surgery is relatively low, and too much cornea needs to be cut and the surgery is irreversible. In addition, patients with high myopia are prone to complications of fundus changes. If the patient develops fundus disease, myopia surgery cannot solve the fundus problem and surgery is not necessary. Patients with high myopia need to make it clear that surgery does not help prevent or treat fundus pathology, as surgery only changes refractive power and does not help with vision loss caused by fundus disease. Therefore, regular fundus examinations are still needed after surgery. In conclusion, patients with high myopia are not absolute contraindications to myopia surgery, but whether they can have surgery or not, they need to improve their corneal condition and other related examinations.
