Astigmatism in children is usually not reversible, but it can be corrected with prescription lenses to improve the child’s vision. Astigmatism is a refractive error in which the refractive power of the patient’s eye is different at different meridian lines, so that when parallel light rays are refracted through the refractive system they do not form a focal point on the retina, but rather two lines of focus. Once astigmatism occurs, it usually cannot be cured, so children with astigmatism usually cannot recover. Mild astigmatism usually does not affect vision and treatment is usually not necessary. Astigmatism of moderate to high severity can affect a child’s vision, and the child may experience discomfort such as decreased visual acuity and double vision, which can be corrected with eyeglasses to improve vision. If the child does not want to wear glasses in adulthood, refractive surgery can be used to correct the astigmatism, such as corneal laser surgery, intraocular lens implantation, etc., in order to improve vision. Parents are advised to bring their children with astigmatism to the clinic for evaluation of their condition and treatment as prescribed by the doctor.
