500 degrees of myopia degree is high, adults who meet the conditions can recover through laser myopia surgery or have lens eye IOL implantation, minors through adequate rest, keratoplasty lens can reduce the degree of myopia to a certain extent, for myopia deepening has a relatively delayed effect, but can not completely stop the development of myopia, and can not cure myopia. In case of myopia in minors, because they are still in the vision development period, they may recover the degree of the pseudomyopia component through sufficient rest, such as: 1. not squinting to see, not lying down to read; 2. intermittent eye use: after every half hour of close eye use, rest for about 10 minutes or look into the distance; 3. reasonable diet, more outdoor activities: regular eye examination and health care. In case of true myopia in minors, it can be treated by keratoplasty, which is a reversible non-surgical physical orthopedic treatment method that gradually changes the curvature of the cornea by wearing a specially designed rigid gas permeable contact lens to reduce myopia and improve naked eye vision. The purpose of this non-surgical treatment is to temporarily improve naked eye vision or reversibly reduce the existing spectacle prescription, and does not cure myopia. Adults whose myopia has stabilized can have myopia corrected with myopic laser surgery or IOL implantation in the lens-bearing eye. Myopia laser surgery uses a laser to cut the cornea and permanently change the curvature of the cornea to treat myopia. Lens IOL implantation is performed by implanting a concave lens in front of the lens of the human eye to correct myopia, which is equivalent to wearing glasses inside the eye and achieving good naked eye vision. In summary, patients with 500 degrees of myopia who meet the conditions can recover through myopic laser surgery or IOL implantation in eyes with a lens; minors can partially recover or delay the progression of myopia through OK lenses, but cannot be cured.
