PURPOSE: To evaluate refractive and visual outcomes of small incision guided human cornea treatment (SmartSight; SCHWIND eye-tech-solutions) in the treatment of myopic astigmatism with the use of a new femtosecond laser system.
METHODS: This retrospective, observational case series study included 104 eyes of 56 patients who underwent SmartSight to correct myopic astigmatism and completed the 3-month follow-up. Procedures were performed with a SCHWIND ATOS femtosecond laser.
RESULTS: Preoperatively, mean manifest spherical equivalent refraction was -6.12 ± 1.99 diopters (D) (range: -3.00 to -11.50 D) and astigmatism was 1.02 ± 0.56 D (range: 0.25 to 2.75 D). Three months postoperatively, it was +0.47 ± 0.32 D (range: -0.75 to +1.00 D) and 0.27± 0.22 D (range: 0.00 to 0.75 D), respectively (both P < .05). Spherical equivalent correction within ±0.50 D was achieved in 62 eyes (60%), and cylindrical correction in 90 eyes (87%). Preoperative corrected distance visual acuity (CDVA) was 20/20 or better in 94 eyes (90%) and postoperative uncorrected distance visual acuity was 20/20 or better in 96 eyes (92%). No eye lost two or more Snellen lines of CDVA.
CONCLUSIONS: Myopic astigmatism correction with Smart-Sight provided good results for efficacy, safety, predictability, and visual outcomes in the first 3 months of follow-up. [J Refract Surg. 2021;37(5):304-311.].
