Abstract:
Femtosecond laser has been widely used in corneal refractive surgery.The refractive state, corneal tissue structure and biomechanical properties are changed through cutting the corneal tissue.Femtosecond laser-assisted in situ keratomileusis(FS-LASIK)and small incision lenticule extraction(SMILE)are the most commonly used femtosecond laser corneal refractive surgery.In this study, the structural basis of corneal biomechanical properties, the commonly used methods for corneal biomechanics measuring, biomechanical effect of corneal flap thickness, side-cut angles, residual stromal bed thickness, flap hinge position for F-LASIK and the size of corneal incision, optical zone diameter, cap thickness, tissue cutting thickness for SMILE on corneal biomechanics are reviewed.
