Myopia is also called refractive error, children 200 degrees of myopia is mild myopia, usually can be corrected by various means, parents are advised to take their children to the regular hospital to check the refractive error. If the child has 200 degrees of myopia, there is a possibility of pseudomyopia. If it is clear that the child has simple pseudomyopia, you can help prevent myopia from worsening by correcting bad eye habits, ensuring rest, relieving fatigue, and doing regular vision reviews. But if it is determined to be a mixture of true and false myopia or true myopia, at this time not only to correct bad habits, but also under the guidance of a doctor, choose optical correction, surgical correction and other methods to correct to avoid aggravation: a. Optical correction: 1, frame glasses: wearing frame glasses is currently more common, and safer means of correction, the principle is to choose the patient to obtain normal vision of the lowest degree of concave lenses; 2, corneal contact lens: choose optical properties, good permeability of the rigid corneal contact lens on the youth vision correction or delay may have a certain role, the advantage of the method is a larger field of vision and does not affect the appearance; 3, keratoplasty: also known as OK lens, is a special design of high oxygen permeable rigid lens, the principle of action is to compress the central optical area of the cornea with the help of corneal contact lens, reduce refractive power, to achieve the role of correction, improve The effect is to reduce the refractive power by compressing the central optical area of the cornea with the help of a corneal contact lens to achieve correction and improve the naked eye vision. However, it only lasts for a certain period of time, and once you stop wearing it, your vision will return to its original state. It is important to note that the fitting and use of these glasses are demanding, and improper fitting may lead to more serious complications, and the child’s autonomy is poor, so careful consideration is needed. Second, surgical correction: common surgeries include keratomileusis, intraocular refractive surgery, scleral refractive surgery, etc. Specific surgical methods need to be selected according to the actual situation. It should be noted that refractive surgery has requirements for age, usually requiring 18 years of age or older, after the body has stopped growing and developing, before it can be performed. Therefore, if you are considering surgery, you can choose to wear glasses first and wait until you are an adult before undergoing surgery, and there are risks associated with surgery, so it is recommended to consult your doctor.
