<unk> is a defect of the eye, where vision is blurred by an irregularly shaped cornea.  The cornea, instead of being shaped like a sphere, is ellipsoidal (like an egg) and reduces the cornea's ability to focus light.<unk> is a refractive error of the eye in which there is a difference in degree of refraction in different meridians (i.e., the eye has different focal points in different planes.) For example, the image may be clearly focused on the retina in the horizontal (sagittal) plane, but not in front of the retina in the vertical (tangential) plane.<unk> causes difficulties in seeing fine detail, and in some cases vertical lines (e.g., walls) may appear to the patient to be leaning over. The effects of<unk> of the eye can often be corrected by prosthetic lenses with a cylindrical lens (i.e. a lens that has different radii of curvature in different planes), contact lenses, or refractive surgery.
