lenticular astigmatism definition
(redirected from lenticular astigmatism) Also found in: Dictionary, Thesaurus, Medical, Wikipedia. Related to lenticular astigmatism: corneal astigmatism. (ÉstÄ­g`mÉtÄ­z'Ém), type of faulty vision caused by a nonuniform curvature in the refractive surfacesâusually the cornea, less frequently the lensâof 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.
