Myopia of 700 degrees is classified as high myopia, also called pathological myopia. Adult patients who meet the conditions can recover refractive error, but it does not reduce the risk of developing associated eye diseases due to pathological myopia. Myopia is generally classified as mild, moderate, or high according to the degree (degrees) of myopia. Every 300 degrees is a ladder, i.e. 0-300 degrees is mild, 300-600 degrees is moderate, and over 600 degrees is high. High myopia is a special group of people with pathological myopia, and some studies have found that the causes of high myopia may be different from low to moderate myopia. 700 degrees of myopia is high myopia, and if the patient is an adult and stable, and the eye condition meets the conditions after hospital examination, the refractive error can be corrected through myopic laser surgery or lens IOL implantation to change the refractive error of the cornea or lens. The use of keratoplasty in minors can reversibly reduce myopia and relatively slow down the progression of myopia, but it does not completely stop the progression of myopia and cannot cure it. However, patients with pathological myopia are often at high risk for many eye diseases, such as retinal detachment, open-angle glaucoma, and macular degeneration. Neither surgery nor keratomileusis can reduce the incidence of these diseases, and patients with high myopia still need to have their fundus reviewed annually in an outpatient clinic. In summary, 700 degree myopia can be restored if the eye conditions are met, but it should be noted that the various restoration methods currently available cannot change the risk of other eye diseases caused by high myopia itself.
