Two Femtosecond Laser LASIK Platforms: Comparison of Evolution of Visual Acuity, Flap Thickness, and Stromal Optical Density

Abstract

Although both devices provided satisfactory visual outcomes, significant differences were detected in flap parameters. Flaps made with the iFS 150-kHz FS laser were thinner, more uniform, transparent, and accurate compared with those obtained with the LenSx FS laser.
