Description

technical field [0001] The invention relates to the technical field of laser eye surgery, in particular to a laser-induced plasma spectroscopic analysis device and method for cornea measurement. Background technique [0002] For patients who are not suitable for laser eye surgery, the most common reason is that they are prone to keratoconus, and keratoconus is also a major clinical manifestation of laser eye surgery failure. Whether the patient is prone to keratoconus is a problem that must be considered in laser eye surgery. [0003] At present, the examination of whether a patient is prone to keratoconus is mainly to measure the corneal biomechanical parameters of the patient, because the corneal biomechanical parameters of keratoconus patients are all lower than normal values. [0004] At present, the only instrument capable of measuring corneal biomechanical properties clinically is the eye response analyzer. The measurement method of the eye response analyzer is simil...
