Astigmatism is a type of refractive error that is usually caused by congenital irregularities in the cornea. For the correction of this condition, there are mainly the following methods. First, wearing frame glasses, which is currently the most applied and the most classic method. Second, wearing corneal contact lenses. There are soft corneal contact lenses and rigid corneal contact lenses. For children, the preference is for rigid corneal contact lenses. Third, after the age of 18, refractive status reaches stability, refractive surgery treatment can be considered. There are keratoconus surgery and intraocular refractive surgery. Other than this, there is no method that can completely cure, or bring down the astigmatism. There is no scientific basis for any propaganda for the treatment of astigmatism, so do not believe in it blindly.
