Abstract
Purpose :
The purpose of this study was to comparative investigate two myopic correction femtosecond laser techniques: femtosecond-assisted LASIK was compared to an all femto-second laser Small Incision refractive Lenticule Extraction (SMILE). Six-month refractive outcomes were comparatively evaluated.
Methods :
This is a single-center, retrospective analysis of 100 consecutive myopic patients. Group-A was treated with the SMILE (n=48 eyes), while the other eye (group-B) with LASIK (n=52 eyes). The LASIK procedure employed the Alcon Refractive surgery platform (Alcon Surgical, Ft. Worth, TX) comprised of the FS200 femtosecond and the EX500 excimer laser. The SMILE procedure employed the 500 kHz VisuMax® femtosecond laser (Carl Zeiss Meditec AG, Jena, Germany). All operations were performed by the same surgeon (AJK).
Results :
LASIK SEQ corrected: -5.12±2.74 D(range -1.50 to -12.00). 6-month results: 82% within ± 0.25D, 87% within ± 0.50D; 91% had 20/20 UDVA or better; 54% no change in Snellen lines, 46% gained 1 or more; predictability r^2 = 0.999.
SMILE SEQ corrected: -4.63±1.90 D (range -2.50 to -9.50). 6-month results:
84 % within ± 0.25D, 95% within ± 0.50D; 88% had 20/20 UDVA or better; 45% no change in Snellen lines, 55% gained 1 or more; predictability r^2 = 0.972.
Conclusions :
FS-assisted LASIK and SMILE appear to have similar refractive results up to 6 months.
