If the patient has normal vision, no visual fatigue or visual disturbance, mild astigmatism generally does not require correction. If the patient has moderate to high astigmatism, resulting in blurred vision, or symptoms such as eye pain, tearing, and conjunctival congestion, he or she needs to recover through treatment, which mainly includes columnar lens correction and surgery: 1. Columnar lens correction: This method is suitable for high astigmatism, and there are two common methods, one is to use optical lenses, concave columnar lenses for myopic astigmatism and convex columnar lenses for hyperopic astigmatism. There is also a method to correct astigmatism with contact lenses. Contact lens correction is suitable for irregular astigmatism, such as astigmatism caused by cone cornea, which is usually corrected with contact lenses; 2. Surgical treatment: the main surgical methods commonly used in clinical practice are corneal refractive surgery, intraocular refractive surgery, and artificial lens implantation. There are more treatment methods for astigmatism. For patients with astigmatism treatment needs, a personalized treatment plan should be developed by a doctor according to the structural characteristics of the affected eye after completing relevant examinations.
