Abstract

Purpose
To evaluate the clinical outcomes of a new refractive corneal lenticule extraction method (SmartSight) using a Schwind ATOS femtosecond laser (Schwind Eye-Tech-Solutions, Kleinostheim, Germany).
Methods
The medical records of 338 eyes of 170 patients who underwent SmartSight treatment from April to September 2022 and were followed-up for at least 3 months were retrospectively analyzed. The patients were followed-up at 1 day, 1 week, and 1 and 3 months after operation. Refraction, visual acuity, and intraocular pressure were measured at each visit.
Results
Preoperatively, the uncorrected distant visual acuity was 1.26 ± 0.33 logarithm of minimum angle or resolution (logMAR) and the spherical equivalent was -4.52 ± 1.77 diopters. The 3-month, postoperative, uncorrected distant visual acuity was 0.01 ± 0.03 logMAR and the spherical equivalent was -0.12 ± 0.22 diopters. The 3-month data were as follows: efficacy of refractive surgery, 0.99 ± 0.11; safety, 1.00 ± 0.05; predictabilities at ±0.5 and ± 1.0 diopters, 97% and 100%, respectively.
Conclusions
Myopic astigmatism correction using the SmartSight method was effective, safe, and predictable in terms of visual outcomes.
