Patients \u226440 years old with a corrected distance visual acuity of &gt;20 \/ 25, manifest refractive spherical equivalent \u226410.0 diopters (D), and cylinder refraction &lt;5.0 D were included. Evaluation of visual outcomes was conducted at 1 day and 1 month postoperatively.Results: A total of 258 eyes from 132 patients were analyzed. Among the total, 94% achieved an uncorrected distance visual acuity (UDVA) of 20 \/ 20 at 1 month postoperatively. Of the eyes with high myopia, 81% achieved a UDVA of 20 \/ 20, followed by 97% and 99% in moderate and low myopic eyes, respectively. Spherical equivalent refraction (r = 0.273, p &lt; 0.01), optic zone (OZ; r = 0.260, p &lt; 0.01), cap thickness (r = 0.209, p &lt; 0.01), and residual stromal thickness (RST; r = 0.256, p &lt; 0.01) showed a significant but weak correlation with UDVA at 1 month postoperatively. There is increasing risk to get &lt;20 \/ 20 UDVA in right eyes (odds ratio [OR], 3.101; p &lt; 0.045), eyes with high myopia (OR, 9.964; p &lt; 0.01), 100-\u03bcm cap thickness (OR, 4.578; p &lt; 0.01), \u22646 mm OZ (OR, 10.556; p &lt; 0.01), and &lt;300-\u03bcm RST (OR, 9.100; p &lt; 0.01) at 1 month postoperatively.Conclusions: SMILE Pro results in promising visual outcome in early postoperative period. Patients with low to moderate myopia have better visual outcomes than those with high myopia. A small OZ, thin cap thickness, and low RST could increase the risk of not achieving the maximum visual outcome after SMILE. A prospective study with a longer follow-up period that includes comprehensive variables is needed to fully understand the factors affecting visual acuity after SMILE.<\/jats:p>","DOI":"10.3341\/kjo.2025.0040","type":"journal-article","created":{"date-parts":[[2025,9,22]],"date-time":"2025-09-22T00:39:01Z","timestamp":1758501541000},"page":"501-512","update-policy":"https:\/\/doi.org\/10.3341\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Factors
