Astigmatism

Astigmatism

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 soccer ball. Depending on how light rays enter the cornea, they may be focussed to different points – see the diagram below.

Options for Correction of Astigmatism

There are many options available for permanent correction of astigmatism and these include:

  • Laser eye surgery
  • Laser astigmatic keratotomy
  • Laser Limbal relaxing incisions
  • Toric Implantable Contact Lenses
  • Toric Intraocular Lenses
