How to treat true myopia
summary
Once true myopia is formed, it is irreversible. It is the organic change of eyeball. The anterior and posterior axis of the eyeball becomes longer, and the external object image is imaged in front of the retina through the refractive system of the eye, and there is no clear object image on the retina. This kind of organic change can not shorten the eyeball and change the diopter by any method except surgery, which is the reason why it is difficult to cure myopia. Here is how to treat true myopia.
How to treat true myopia
First: once the formation of true myopia, whether it is high myopia, or low myopia situation is the same. (1) before lens fitting, the true degree of myopia should be found out through the difficult light detection. For teenagers, optometry should be carried out under cycloplegia, so as to control the regulating effect and eliminate pseudomyopia.
Second, wearing contact lenses can increase the visual field, have better cosmetic effect, and can significantly reduce the Anisometropia of two eyes, so as to maintain the binocular visual function. Young people with myopia, not only can use contact lens to increase vision, but also can press the cornea to prevent the development of myopia. But we must pay attention to cleanliness, disinfection and maintenance as required and frequent replacement.
Third: Telescope glasses, very high myopia patients or macular lesions, by telescope glasses, often can read or do near work. The magnification of this kind of glasses is 1.8 times, so the far vision can be enhanced by 2% - 3.5%, and the near vision can be enhanced by up to 5 times. Because the field of vision is too small, it can not be used on the road.
matters needing attention
After incision of the corneal surface, the curvature of the cornea becomes flat, thus reducing the myopia. It is generally believed that 3.00d myopia can be corrected. Because the long-term effect of this method is still difficult to confirm, and the indications and contraindications should be strictly selected, and there is the possibility of surgical complications. Therefore, it is still difficult to carry out it universally.
