Abstract
The present invention relates to a non-contact portable tonometry system and tonometry method using a difference in infrared intensity. A nozzle module receives compressed air from a compressed air supply source and sprays the same through an air spray port to a cornea of a subject, thus to cause corneal deformation. An infrared ray sensor is disposed in the nozzle module to emit infrared rays to the cornea and measure an amount of light reflected from the cornea. A controller converts the amount of light measured by the infrared ray sensor before and after the deformation of corneal into intraocular pressure.
