OPERATION PRINCIPLE
Ocular Pressure Measurement:
By ejecting air from the measuring nozzle to the cornea, detect by a pressure sensor the internal cylin-
der pressure required for the cornea to reach a prescribed deformed state (with a certain plane area),
and calculate the ocular pressure value by computing. Detecting the applanation of cornea is per-
formed, irradiating the cornea by near infrared light from a IOP measurement optical system (XY LED)
and receiving the reflected beam by an applanation sensor.
