There is no clinical method to restore the length of the eye axis, and only some measures can be taken to prevent and control the growth of the eye axis. When the patient’s eye axis length grows, it may lead to thinning or even degeneration of the peripheral retina, which may lead to more serious complications such as retinal tears, detachment or choroidal neovascularization and other lesions, causing permanent damage to the patient’s vision. There is currently no effective clinical method to shorten the eye axis, and we need to try to control the lengthening of the eye axis as much as possible. The lengthening of the eye axis is usually caused by the growth of myopia. Therefore, patients need to control the development of myopia, such as wearing keratoplasty lenses and increasing outdoor activities every day in order to relax the eyes. It is recommended that patients with abnormal eye axes should seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
