Abstract To solve the value traceability of non-contact tonometer, through deeply analyzing of the Imber-Fick and Glodmann tonometer principle that involved in the intraocular pressure testing, a model eye device for non-contact tonometer is independently designed and developed, where the composite structure of the cornea and sclera, and the system correction method are adopted, the same corneal deformation and the inner pre-set pressure are controlled both during the testing and tracing, the external standard value of intraocular pressure are traced back to the quality and length, using a L-shaped torque balance. The experimental results show that the device has good repeatability and stability, where the resolution is up to 1 Pa, and pressure is continuously adjustable. The expanded uncertainty reaches at 0.08 kPa (k=2).
