Initial Experience And Outcomes Of Refractive Lenticule Extraction With The Smartsight Procedure

To report the refractive and visual outcomes of refractive lenticule extraction in the first series of eyes treated at OCL Vision with the SmartSight® (SCHWIND eye-tech-solutions, Kleinostheim, Germany) for the correction of myopia with astigmatism. 

OCL Vision, London, UK

This was a retrospective analysis of the first consecutive patients treated with SmartSight lenticule extraction between November 2022 and June 2023 at OCL Vision. Patients older than 18 years, with astigmatism up to -2.50D and myopia up to -9.00D were treated with a refractive target of emmetropia. Follow-up was at 1-day, 1-2 weeks, and 3-months after surgery. Uncorrected distance visual acuity (UDVA) and best-corrected distance visual acuity (CDVA), and subjective refraction were measured. Intraoperative and postoperative complications were recorded.

A minimum of 80 eyes of 40 patients will be included. At this time, 36 eyes of 20 patients are available for analysis. Mean age was 31.8 ± 5.7 years; mean preoperative spherical equivalent (SEQ) was -6.13 ± 1.56 D. Mean UDVA was 0.13 ± 0.18 logMAR at Day-1, and -0.04 ± 0.17 logMAR at Month-3. There was no loss of CDVA. Mean SEQ at Month-3 was -0.16 ± 0.65 D, showing a small myopic regression compared to week 1-2; 94% of eyes were within ±1D of refractive target. There were no intra-operative complications, or post-operative complications.

SmartSight was a safe and effective refractive procedure in this first series of eyes. Refractive accuracy might need to be adjusted with a nomogram.
