What is the name of the technique that uses a puff of air to measure intraocular pressure?

The technique that utilizes a puff of air to measure intraocular pressure is known as Non-Contact Tonometry. This method is often referred to as "air puff tonometry," where a gentle blast of air flattens the cornea momentarily, and the device measures the resistance of the cornea to the air. The measurement process is quick, painless, and does not require contact with the eye, making it a comfortable option for patients.

Non-Contact Tonometry is particularly useful for screening purposes or when dealing with patients who may be anxious about more invasive methods. This technique can provide a reliable estimate of intraocular pressure without the need for topical anesthetics or contact lenses, which are usually required for other methods of tonometry.

Understanding this method is essential for ophthalmic assistants because it allows for efficient, effective assessment of eye health, specifically in screening for conditions like glaucoma, which can be indicated by elevated intraocular pressure.
