Cirugía de astigmatismo
Astigmatism is caused by an irregularly curved cornea, where one meridian is longer than the other. As a result, light entering the eye is not evenly focused on the retina, leading to blurred vision. This refractive defect occurs when light rays entering the eye are not refracted equally in all meridians, affecting vision at both near and far distances. Astigmatism is often associated with myopia or hyperopia. The irregular shape of the cornea is the most common cause, although it can also be caused by the irregular geometry of the lens.


  • The irregular shape of the cornea.
  • It is a hereditary condition.
  • Eye trauma.
  • A consequence of an underlying disease.
  • Eye injuries.


  • Unequal sharpness in horizontal, vertical, or oblique lines.
  • Perception of distorted images.
  • Headaches.
  • Blurred vision.

The treatment of astigmatism aims to improve the vision of patients who experience blurred or distorted vision at both near and far distances. There are several procedures available to correct this refractive defect, including:
