We analyzed 120 right eyes from 120 healthy consecutive myopic patients who underwent aaPRK or tPRK to correct myopia of up to 6 diopters and astigmatism of up to 2 diopters. The WaveLight EX500 excimer laser (Alcon Laboratories, Inc.) was used in all cases. Visual acuity, subjective refraction, and Pentacam AXL\u00ae measurements were performed at the preoperative visit and at 6-months follow-up visit. Pentacam AXL\u00ae software was used to assess corneal optical density in various annuli for different corneal depths and anterior corneal HOA (6\u2005mm area of analysis).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Preoperative spherical equivalent values were similar between groups preoperatively (\u22123.07\u2009\u00b1\u20091.52 and \u22123.38\u2009\u00b1\u20091.46 in the aaPRK and tPRK groups, respectively). There were no statistically significant differences in visual acuity and postoperative refraction between groups. Postoperative corneal densitometry did not show statistically significant differences in any of the areas studied and both surgical procedures obtained similar results. However, analysis of HOA showed statistically significant differences between the techniques (1.42\u2009\u00b1\u20090.39 and 1.80\u2009\u00b1\u20090.62 for the aaPRK and tPRK groups, respectively; p\u2009=\u20090.000).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Both aaPRK and single-step tPRK gave comparable visual, refractive, and corneal density outcomes.
