Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye. The irregularity can cause blurred vision at all distances, thus causing discomfort and headaches.
Most people have some degree of astigmatism. Slight astigmatism usually doesn’t affect vision or require treatment. Often times, we may explain it as the eye having a football-shaped appearance, rather than a round shape, such as a basketball. Astigmatism can be treated with glasses and/or toric contact lenses. Often times, patients that are undergoing cataract surgery may want to correct their astigmatism with toric intraocular lenses.
