What causes astigmatism in the eye

Acquired astigmatism is mostly irregular astigmatism, which is mainly caused by corneal lesions, such as keratoconus, and the infection of the cornea forms scarring, which requires aggressive treatment of the cause. When these two parts are abnormal due to different reasons, the refractive index of each direction of the meridian is different, resulting in the appearance of astigmatism. Astigmatism in the eye is a condition in which the eye has refractive error that causes blurred vision.It is generally divided into two conditions, one is congenital astigmatism;

What is the treatment of astigmatism

Astigmatism is mainly due to the change of the curvature of the cornea, which leads to the refractive index of light passing through different corneal surfaces is not the same, therefore, patients will have double vision, blurred vision, and it is easy to cause visual fatigue in a short period of time, resulting in uncomfortable symptoms such as eye swelling and headache. At present, the main clinical methods for correcting astigmatism include eyeglasses, orthokeratology lenses and refractive surgery. In adult patients with high astigmatism, refractive surgery may be considered to correct astigmatism.

Symptoms of astigmatism and amblyopia in children

If it is moderate to high astigmatism, the child's eyes will be affected, and the clinical manifestations are poor vision both far and near, and it is easy to squint.If a child has astigmatism in the eye, the general clinical manifestations are closely related to the degree of astigmatism. In general, with mild astigmatism, the child's eyes will not be affected too much, and the vision may be normal. Some patients may even experience eye fatigue.
