This invention provides a corneal surgery risk evaluation method and system thereof. Utilizing a mechanical numerical model to evaluate stress differences before corneal surgery and after, and further providing a suggested surgical path and risk after surgery. The evaluation method, comprising: measuring Intraocular pressure (IOP) inputting geometric parameters and material parameters of multi-layer of corneal constructing a first corneal numerical model constructing a second corneal numerical model with at least one cutting path character evaluating whether the cutting path character should be re-constructed or not.
