The first group received a <jats:italic>t<\/jats:italic>PRK treatment with the Amaris750 excimer laser (Schwind eye-tech solutions). The second group received a combined PTK\u2212PRK treatment with the MEL90 excimer laser (Carl Zeiss). Only healthy eyes with no previous surgery and a spherical equivalent (SE) of \u22121 to \u22128 diopters (<jats:italic>D<\/jats:italic>) were included. Preoperative spherical equivalent (SE), age, and sex were matched among the two groups. All treatments were performed by the same surgeon in different clinics.
