Astigmatism is a very common vision condition that causes blurred vision due either to the irregular shape of the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.
Astigmatism frequently occurs with other vision conditions like nearsightedness (myopia) and farsightedness (hyperopia). Together these vision conditions are referred to as refractive errors because they affect how the eyes bend or "refract" light. The specific cause of astigmatism is unknown. It can be hereditary and is usually present from birth. It can change as a child grows and may decrease or worsen over time.
The John-Kenyon American Eye Institute offers blade-free, laser-only LASIK surgery as well as other refractive surgeries that may be able to correct astigmatism. During your evaluation your doctor will determine the best option for your vision needs. Learn more about LASIK and other Laser Vision Options here.
