(redirected from lenticular astigmatism) Also found in: Dictionary, Thesaurus, Medical, Wikipedia. Related to lenticular astigmatism: corneal astigmatism. (ÉstÄ­g`mÉtÄ­z'Ém), type of faulty vision caused by a nonuniform curvature in the refractive surfacesâusually the cornea, less frequently the lensâof the eye. As a result, light rays do not all come to a single focal point on the retina. Instead, some focus on the retina while others focus in front of or behind it.
Astigmatism is a vision condition that causes blurred vision due either to a misshapen cornea or sometimes because of an irregular curvature of the lens inside the eye. Problems with either the cornea or the lens prevents light from focusing properly on the retina. When this happens, vision becomes blurred and/or distorted at any distance. Astigmatism is a common vision condition, and can occur jointly with myopia (nearsightedness) and hyperopia (farsightedness). Most people have some degree of astigmatism. Slight amounts of astigmatism usually don't noticeably affect vision and don't require treatment.
