Correcting Astigmatism

Are you getting eye strain and headaches, especially after reading? These are typical symptoms that your eye(s) may have astigmatism. At Fendalton Eye Clinic the astigmatism in your eye(s) can be safely and accurately corrected with precision utilising the unique seven dimensional eye tracking of the Schwind Amaris 1050R excimer eye laser.

What causes astigmatism?
Astigmatism is caused by an irregular shape of the corneal surface. A normal cornea is spherical shaped giving an even, clear image. When you have astigmatism the corneal surface is oval in shape and the focusing power of the cornea becomes uneven. A good analogy is to consider the cornea to be shaped like a soccer ball, when you have astigmatism it is shaped more like a rugby ball. This leads to formation of an image that is distorted or tilted causing blur for both distance and near vision. This blur can lead to a headache when left uncorrected. Astigmatism is incredibly common and most people have a small amount in both eyes, even people who do no wear glasses.

Can astigmatism be corrected?
Dr. Kent has particular interest in correcting astigmatism. With HD LASIKā„¢ we have the ability to reshape the front surface of the cornea giving it an even, spherical surface correcting for any astigmatism that may be present in the eye. Recently, we installed the new Schwind Amaris 1050RS laser which is designed to precisely correct astigmatism. It tracks the eye throughout treatment and compensates for any eye movement that may occur. This ensures precision, safety and comfort for all of our patients.

For Keratoconus patients with very high irregular astigmatism our Keraring and Crosslinking procedures can help improve your condition significantly.
