The non-contact computerized tonometer, also known as the air puff test, is the applanation tonometer that uses air for IOP measurement and is extremely common for screening patients in comprehensive eye examinations. For instance, non-contact tonometers (NCT), as compared with GAT, may underestimate high IOPs and overestimate low IOPs. Clinicians need to develop a consistent, reproducible and reliable technique for obtaining IOP measurements so that they can be compared with confidence over time.

While IOP measurements are important, you must consider whether its necessary in the balance of causing more corneal insult, delaying healing or increasing a patients chances of corneal infection. The index finger of both hands was used to apply pressure consecutively on the eyeball through the upper eyelids and attempt to assess the eye stiffness. Instead of using GAT for patients with astigmatism, consider using the Tono-Pen, a pneumotonometer or other devices if a patients cornea is significantly irregular (from refractive error, scarring, ectasia, etc.). Placing too much fluorescein into the eye will make the mires too thick, causing the IOP reading to be overestimated.
