Can adult astigmatism be corrected?

Adult astigmatism can be corrected, depending on the type and degree of astigmatism. For physiological astigmatism, glasses, contact lenses, or refractive surgery can be used to improve vision. If acquired astigmatism, such as the formation of corneal scars caused by previous keratitis and corneal ulcers, or caused by corneal trauma and keratoconus, due to the irregular shape of astigmatism, it is difficult to correct vision to normal by these conventional methods. If it is more serious, keratoplasty can be used to improve vision. Therefore, adults who show astigmatism need to go to the hospital for a detailed examination before an accurate treatment plan can be developed.
