The article discusses the importance of contrast sensitivity in aiming for overall postoperative spherical aberration of +0.10 µm. Studies have shown that an increase in spherical aberration is associated with a decrease in visual performance as measured by contrast sensitivity. By measuring the spherical aberration of the cornea, the surgeon can determine how much spherical aberration must be counteracted by the intraocular lens to achieve overall postoperative spherical aberration.
