6.-MONTH FOLLOW UP OF NOVEL LENTICULAR PROCEDURE - SMARTSIGHT

To evaluate refractive and visual outcomes over a six-month period of Small Incision Guided Human-cornea Treatment (SmartSight®, SCHWIND eye-tech-solutions, Kleinostheim, Germany) in the treatment of myopic astigmatism with the use of a new femtosecond laser system.

Eye clinic Svjetlost, Zagreb, Croatia

This retrospective, observational case series included 90 eyes of 45 patients who underwent SmartSight to correct myopic astigmatism and completed at least 6-month follow-up. All procedures were performed by the same surgeon using the SCHWIND ATOS® femtosecond laser. All patients were evaluated preoperatively for suitability for laser refractive surgery and followed up for a minimum of 180 days. Analysis of visual and refractive outcomes, as well as Alpins Method for the analysis of Astigmatism has been performed.

 

This non-randomized prospective cases series enrolled 90 eyes of 45 patients. All patients underwent uneventful SmartSight lenticule extraction. Preoperatively, mean spherical manifest refraction(MRSE) was -5.1±1.9 diopters(D)(-1.88 to -7.5), and astigmatism was -0.72±0.43D(-2.00 to -0.25). Spherical equivalent correction within ±0.50D was achieved in 87 eyes (96.6%). Postoperative uncorrected (UDVA) was 20/20 or better in 94 eyes(94%). No eye had lost two or more Snellen lines of CDVA. The central cap thickness for all cases was set to 130 μm it was evaluated on day 30 mean achieved central cap thickness was 124,23 μm (SD ± 11,60).

 

This new femtosecond laser platform (Schwind ATOS) provides a reliable and precise device for refractive laser vision correction. Patients had a quick visual recovery and the UDVA on day 180 was excellent for all patients in this non-randomized study. ATOS represents a new platform for both flap creation and lenticular extraction with very promising early results.
