Overview
Astigmatism means that the cornea is distorted – shaped like a rugby ball rather than a sherical football. Most astigmatic corneas have two curves – a steeper curve and a flatter curve. This causes light to focus on more than one point in the eye, resulting in blurred vision at distance or near.
Astigmatism often occurs along with short sightedness or long sightedness.
Signs and Symptoms
· Blurred vision (near and distance)
Detection and Diagnosis
Astigmatism can be detected and measured with corneal topography, keratometry, vision testing and refraction.
Treatment
Astigmatism can be corrected with spectacles, contact lenses, or surgically.
