<jats:sec>
<jats:title>Purpose</jats:title>
<jats:p>To compare refractive outcomes after transepithelial photorefractive keratectomy (<jats:italic>t</jats:italic>PRK) and combined phototherapeutic keratectomy (PTK−PRK) procedure using two different excimer laser platforms for correction of myopia and myopic astigmatism.</jats:p>

<jats:title>Methods</jats:title>
<jats:p>In this retrospective multicenter study, we compared the results of two different PRK methods. 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−PRK treatment with the MEL90 excimer laser (Carl Zeiss). Only healthy eyes with no previous surgery and a spherical equivalent (SE) of −1 to −8 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. This study was approved by the local Ethics Committee (No. 2022–1980).</jats:p>

<jats:title>Results</jats:title>
<jats:p>We included 154 eyes of 86 patients in our study. There was no difference in predictability of SE between the two groups. Efficacy and safety indices were equally high in both groups. Similarly, no significant differences were seen in change of higher order aberrations (HOA) between the two groups (<jats:italic>p</jats:italic> > 0.05). No complications occurred.</jats:p>
</jats:sec>
<jats:sec>
<jats:title>Conclusion</jats:title>
<jats:p>Both investigated methods provide safe and effective refractive results. The combination of PTK with PRK may be a suitable option to the already used one-step <jats:italic>t</jats:italic>PRK for the correction of myopia.</jats:p>
