Can the eye height astigmatism be cured

Astigmatism is a refractive condition in which parallel rays enter the eye and do not form a focus on the retina, but form two focal lines. Astigmatism is clinically divided into two categories: regular astigmatism and irregular astigmatism. Irregular astigmatism has no rules to follow and may be caused by corneal scars caused by keratoconus or inflammation or trauma. High astigmatism can be corrected by wearing cylindrical lenses or contact lenses to restore vision. For those over 18 years old with astigmatism less than 600 degrees, astigmatic keratotomy or excimer laser refractive keratotomy is also feasible for those with indications.
