Abstract

Abstract: Since the introduction of femtosecond laser (FS) systems for corneal flap creation in laser-assisted in-situ keratomileusis there have been numerous applications for FS laser in corneal surgery. This manuscript details the utility of FS lasers in corneal surgical procedures including refractive laser surgeries, intracorneal ring segment tunnels, presbyopic treatments, and FS-assisted keratoplasty. We also review the role of FS lasers in diagnostic procedures such as two photon excitation fluorescence and second harmonic generation. Highlights: Femtosecond (FS) lasers offer safe and precision planning in corneal surgery. Expanded indications include lenticule extraction, creation of stromal pockets, and keratoplasty. FS-laser two photon excited fluorescence and second harmonic generation offer precision in structural and functional corneal imaging. Laser induced refractive index change is a tissue-sparing technique for correcting optical aberrations.
