👓 The air puff tonometer is a non-contact device that measures intraocular pressure (IOP) by blowing a quick puff of air onto the cornea.
- How it works: The device measures the corneal deformation caused by the air puff.
- Advantages: No direct contact with the eye, reducing infection risk.
- Common use: Often used for glaucoma screening and routine eye exams.
- Considerations: Can be less accurate than contact tonometers (e.g., Goldmann).
