Astigmatism is often found in combination with shortsightedness and farsightedness and contributes to blurry vision. This occurs because the cornea is shaped like a rugby ball rather than a football. Depending on how light rays enter the cornea, they may be focused to different points – see the diagram below.
Options for Correction of Astigmatism
Nonsurgical options for treatment of astigmatism include spectacles with cylindrical lenses or contact lenses.
There are many options available for permanent correction of astigmatism and these include:
- Laser eye surgery
- Laser astigmatic keratotomy
