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.本發明提供一種眼角膜手術風險評估方法,透過力學模型來評估手術前後的應力差異性,並提供建議之手術開刀路徑與開刀後風險。評估方法包含下列步驟:(S1)量測眼壓;(S2)輸入眼角膜中複數層之幾何參數及材料參數;(S3)建立一第一眼角膜數值模型;(S4)建立具有至少一切割路徑特性之第二眼角膜數值模型;(S5)評估是否需重新規劃該至少一切割路徑特性。步驟(S1)~步驟(S6)
