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.

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
