Abstract
A simple way to minimize cross infection from tear droplets during noncontact air-puff tonometry
Highlights
To the Editor—Noncontact air-puff tonometry (NCT) is a routine ophthalmological examination used to measure intraocular pressure (IOP)
A transparent plastic shield was installed between the chin rest and forehead rest and the main mobile unit, and a homemade paper funnel was installed on the sensor (Fig. 1A)
The IOP measurement and droplets screening were repeated using the same volunteer with the protective measure
Summary
To the Editor—Noncontact air-puff tonometry (NCT) is a routine ophthalmological examination used to measure intraocular pressure (IOP). We employed a protective measure and investigated its ability to prevent contamination from tear droplets. A transparent plastic shield was installed between the chin rest and forehead rest and the main mobile unit, and a homemade paper funnel was installed on the sensor (Fig. 1A).
