Preferred Label : astigmatism;
MeSH definition : Unequal curvature of the refractive surfaces of the eye. Thus a point source of light
cannot be brought to a point focus on the retina but is spread over a more or less
diffuse area. This results from the radius of curvature in one plane being longer
or shorter than the radius at right angles to it. (Dorland, 27th ed); Unequal or irregular curvature of the CORNEA (Corneal astigmatism) and/or the EYE
LENS (Lenticular astigmatism) resulting in REFRACTIVE ERROR.;
