Despite the limited published evidence for the proposed damage caused by contact lenses repeatedly crossing the limbal area, as assessed by lens centration and coverage, the change in surface curvature, end of the corneal avascular area and stem cells in this location suggest this is an important aspect of soft contact lens fit . Some practitioners indicate the centre of lens with a cross with the centre of the lens marked by a small cross as this is easier to draw accurately rather than a circle. I suggest a cross to indicate the centre of the cornea, with a circle to mark the relative position of the lens, which has better FACE VALIDITY and allows the position of any crossing of the limbus by the lens edge to be marked .
