非接触眼压计(non-contact tonometer NCT)是不同于普通眼压计的一种压平式眼压计。测量眼压时不必接触眼球,压平(使角膜的一部分变平)通过一个气体脉冲力获得,力作用在角膜上,力的大小与时间成线性正比关系,压平情况由光电法检出,压平眼压计是按Imbert-Fick定理进行的,即眼压等于压平力(角膜变平力)除 Non-contact tonometer (non-contact tonometer) is a tonometer different from the ordinary tonometer. Measuring intraocular pressure without contact with the eye, flatten (make a part of the cornea flattened) obtained by a gas pulse, the force acting on the cornea, the size of the force is linearly proportional to the time, the flattening situation detected by the photoelectric method, Flattening tonometer is based on the Imbert-Fick theorem, which is equal to the intraocular pressure flattening (corneal flattening) except
