Nearsighted patients who also have astigmatism are a common symptom of ophthalmology, which is related to developmental abnormalities and acquired poor eye habits. Patients need to undergo an optometry examination to determine the exact refractive error, and then the refractive error can be corrected by wearing glasses or surgery to improve vision. Refractive errors can lead to vision loss and other symptoms, and can be subdivided into three types: myopia, astigmatism and hyperopia. Myopia and astigmatism can occur at the same time. Patients need to undergo an optometry examination to determine the correct amount of myopia, astigmatism, astigmatism axis and other indicators. Usually, underage patients can wear eyeglasses to correct the refractive error and improve their vision. If adult refractive error patients do not want to wear glasses, patients can have refractive surgery to correct their vision, such as intraocular lens implantation, corneal laser surgery and so on. It is recommended that patients with refractive errors seek medical attention to evaluate their condition and follow the doctor’s instructions.
