We measured the visual acuity, intraocular pressure, automated keratometer, manifest refraction, and topography preoperatively and 1-day, 1-month, 3-month, and 6-month postoperatively.

Refractive astigmatism was significantly decreased in both groups. The mean preoperative and 6-month postoperative refractive astigmatism were 1.85\u2009\u00b1\u20091.07 and 0.99\u2009\u00b1\u20090.51 D, respectively, in the AK group (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u20090.028), and 1.84\u2009\u00b1\u20090.81 and 0.68\u2009\u00b1\u20090.21 D, respectively, in the toric IOL group (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0&lt;\u20090.001).
