Definition: Astigmatic Keratotomy (AK) is a surgical procedure for correcting the shape of the cornea.
Astigmatism is a visual condition in which the cornea is football-shaped instead of spherical, causing the image to be blurred. Astigmatism can be found with nearsightedness or farsightedness. AK can be combined with LASIK or AST (advanced surface treatment) to improve clarity of vision.
The Procedure: Small tangential incisions are placed to flatten the cornea where it is too curved.
