Astigmatism in the eyes is restored to normal by two main treatments: optical correction and surgical treatment, of which wearing a column lens for optical correction is the main treatment for astigmatism.
Astigmatism is a kind of refractive irregularity of the eyes, parallel rays of light entering the pupil can not focus on the focal point, so it can not form a clear image. According to its manifestation, it is mainly regular astigmatism and irregular astigmatism.
Regular astigmatism is corrected with different types of cylindrical lenses according to the type of astigmatism, convex cylindrical lenses for hyperopic astigmatism and concave cylindrical lenses for myopic astigmatism. Mild astigmatism can be left uncorrected if there are no clinical symptoms. Corrective glasses are recommended if there is a decrease in vision or symptoms of visual fatigue and visual disturbances. Patients with high astigmatism who cannot adapt to frame glasses can choose corneal contact lenses for correction.
Irregular astigmatism cannot be corrected with ordinary lenses, but with corneal contact lenses, astigmatism can be corrected; for high astigmatism due to congenital or acquired, surgical treatment is recommended.
When your eyes are checked for astigmatism, it is recommended that you go to a specialized hospital and choose the appropriate correction method according to your condition under the guidance of your doctor.
