Abstract
The present invention provides a laser system for detecting biomechanical properties of the cornea, which comprises a laser for emitting a pulsed laser beam, a beam transmission module, a collecting-filtering module and a spectroscopic analysis unit, the beam transmission module is used for transmitting the laser beam and focusing the laser beam onto the cornea, on the surface of which a laser-induced plasma signal is generated; the laser-induced plasma signals are collected and filtered by the collecting-filtering module; the spectroscopic analysis unit performs spectroscopic analysis on the laser-induced plasma signal to determine the biomechanical properties of the cornea. The present invention further provides a method for detecting the biomechanical properties of the cornea with the above laser system. The same laser system for LASIK surgery is utilized in the present invention to measure the biomechanical properties of the cornea timely and accurately, which improves work efficiency.
