The non-contact tonometer uses an algorithm-controlled air pulse to project gas onto the central corneal surface. By collecting the corneal reflection signal and processing it with proprietary algorithms, it calculates intraocular pressure (IOP). Accurate IOP measurement is essential for early diagnosis of glaucoma and provides critical support for clinical decision–making. Key components include the corneal alignment system, fixation system, air-pulse control system, and signal acquisition system.
