Visual and refractive outcomes of keratorefractive lenticule extraction using VISUMAX 800 (SMILE Pro) to correct myopia in Koreans: a 3-month follow-up study

Year: 2025

Type: article

Abstract: Purpose: The aim of this study was to report the clinical outcomes of SMILE Pro surgery in Korean myopia patients.Methods: A retrospective analysis was conducted on the medical records of 90 patients (178 eyes) who underwent SMILE Pro surgery at our institution between October 2023 and June 2024 and were followed for 3 months postoperatively.Results: Preoperative best corrected visual acuity was 0.009±0.020 (logarithm of the minimum angle of resolution). The average spherical equivalent was –5.13±2.16 diopters (range, –1.00 to –10.10 diopters), and the average astigmatism was –1.21±0.91 diopters (range, 0 to –4.0 diopters). Postoperatively, the uncorrected distance visual acuity at 1 day, 1 week, 1 month, and 3 months were 0.061±0.054, 0.013±0.027, 0.009±0.023, 0.005±0.021, respectively. At 3 months postsurgery, the predictive accuracy for spherical equivalent was 100% within ±0.5 diopters and 98.9% within ±0.25 diopters. For astigmatism, the predictive accuracy was 97.2% within ±0.25 diopters and 99.4% within ±0.5 diopters 97.2% and 99.4%. The scores for the efficacy and safety of refractive surgery at 3 months were both 1.01±0.05.Conclusion: SMILE Pro surgery for myopia correction in Korean patients demonstrated excellent efficacy, safety, and predictive accuracy, with no significant difference compared to conventional SMILE surgery.
