Modern Technology Allows Correction of Cataract and Astigmatism
... What is astigmatism? Astigmatism usually refers to an irregularly shaped cornea (the clear window in front of the eye). This is caused by the cornea being more curved in one direction than the other, much like a football. This causes light to focus at several different points on the back of the eye, ...
