Abstract：Corneal refractive surgery has been carried out in China for nearly 30 years, its safety and effectiveness has been proved by mutiple studies, and the stability and long-term safety of the surgery have been the focus of attention. Cornea is a typical viscoelastic tissue, as an important refractive medium of the eye, its biomechanical characteristics is an important factor affecting the predictability and stability of corneal refractive surgery, involving the indication for refractive surgery, choice of surgical methods and design, safety and stability of surgery. The abnormal changes of corneal biomechanical characteristics are closely related to corneal ectasia and refractive regression after corneal refractive surgery. Therefore, understanding the characteristics of corneal biomechanics and its role in corneal refractive surgery is of great significance for improving the safety, effectiveness and predictability of corneal refractive surgery.
