Children with three or four hundred degrees of astigmatism need to wear glasses to correct it, otherwise it is easy to form amblyopia. In addition, they should also improve the relevant examinations to see if there are eye pathologies, such as corneal topography examination to rule out that it is caused by cone cornea, and if necessary, surgical treatment. Astigmatism is a type of refractive error, which in most cases develops in childhood and is related to a variety of factors such as congenital developmental abnormalities and poor eye habits. Children with astigmatism should be examined by an optometrist to determine the specific degree of astigmatism, astigmatism axis and other indicators, three or four hundred degrees of astigmatism is already a high degree of astigmatism, which will have an impact on the development of vision, and need to be corrected as soon as possible through the wearing of glasses, so as to avoid the formation of amblyopia. If amblyopia has already formed, it can be treated by means of masking therapy. The patient should also go to the ophthalmology department of the hospital to improve the eye examination to see if the formation of astigmatism is related to the underlying eye disease, such as doing corneal topography examination to rule out the high astigmatism caused by conical cornea, if the diagnosis of conical cornea is the cause of the high astigmatism, we can consider corneal crosslinking, corneal transplantation surgery and other treatments. It is recommended that the patient go to the hospital in time, complete the relevant examinations and follow the doctor’s instructions.
