The Impact of Changes in Corneal Back Surface Astigmatism on the Residual Astigmatic Refractive Error following Routine Uncomplicated Phacoemulsification

<div>Change in the sine of the axis of astigmatism at the corneal back surface over the central 3 mm zone (<i>x</i> axis) and the corresponding change in the sine of the axis of residual refractive astigmatic error determined by autorefractometry (<i>y</i> axis) between 1 and 2 months postoperatively. All units are sine of axis in degrees (°).</div>
