Abstract
 
Purpose:
 

To report the visual outcomes, complications and refractive stability of FLEx

 
Methods:
 

Prospective interventional study of femtosecond refractive lenticule extraction (500 MHz VisuMax, Zeiss-Meditec) for the correction of myopia and myopic astigmatism. Target refraction was plano. Follow-up was done at day 1, 1 week, 1 month and 3 months. Uncorrected visual acuity, best corrected visual acuity, manifest refraction and biomicroscopic findings were recorded at each visit.

 
Results:
 

55 eyes were completed as FLEx, Mean preoperative spherical equivalent (SE) was -4.57 +/- 1.64 diopters (D). Mean preoperative sphere was -3.67 D (0.00 to -7.25), and mean preoperative cylinder was -1.80 D (0 to -6.00). Preoperative mean UCVA was 1.27 logMAR, with BSCVA of 0 or 0.1 logMAR.Mean postoperative UCVA at one month was 0.20 logMAR (p = <0.05) , with a SE of +0.019 +/- 1.00 D. At three months a total of 66.6% of eyes achieved UCVA of 20/20, and 100% of 20/40 or better. 80% of eyes were within +/- 1.00 D of emmetropia and 66.6% of eyes were within +/- 0.50D of intended correction. Two eyes (13.3%) lost two or more lines. Optical descentration of the lenticule was recorded in 1 eye.

 
Conclusions:
 

The correction of myopia and myopic astigmatism with femtosecond only refractive lenticule extraction seems to be as safe and effective as other refractive techniques. Still improvements need to be made for the treatment of astigmatism > 4 D
