When the TonoPen first came out, it was invented by the old company “Mentor,” whom sold the device to “Medtronic,” whom finally sold the technology to the current manufacturer “Reichert.” Since that time, the device has changed very little– even it’s shape and size have stayed pretty much constant. We don’t very much mind I suppose, as the device fits in the hand perfectly, does the job comparatively well to a Goldmann Application device, and avoids the dreaded “puff” altogether. And so therefore it looks like a winner. But it should come with saying that the unit does require numbing drops be administered to the patient– yet another tonometry-related thing that will drive patients crazy. We’ve heard horror stories about patients outright refusing any form of IOP measurement from previous experiences and it’s not hard to see why. If it’s not a puff of air, it’s a drop, and then sometimes it’s all of the above- none of these promote a friendly patient experience. We get that IOP measurements have to be invasive to some extent and we also understand that a pretest room must “flow.” So therefore we offer this hardline: a Puff-NCT is efficient but invasive, and the TonoPen is slightly less invasive but less efficient, and other devices such as the iCare Tonometer aren’t really efficient either and they still freak patients out–despite their claims. Maybe we’re just unsatisfied with forms of Tonometry altogether. 


OUR TAKE: A satisfactory and easy way to take IOP measurements in any environment without “puffing” them away.

#1. Take It Anywhere

The TonoPen XL is strangely named “XL” which implies (at least to us) that the unit is extra-large. It’s hardly that, weighing only 2.1 pounds and measuring at 8 inches in length. Perhaps it means something we don’t know- however we do know that it’s incredibly portable, tiny, and light. It sits in the hand perfectly as if it’s supposed to be there, and can literally be taken anywhere.

#2. Just Like your Goldmann

Despite it’s transducer measuring at less than 1mm in length, the handheld TonoPen is just as accurate when compared to a Goldmann Tonometer. This of course comes without all the hassle and time for a Goldmann measurement. It does require a small learning curve when first using it on a patient, however once versed with the device, simple measurements can be obtained with light pressure on the center of the cornea.

Very accurate. Within about 1.5 microns averaging four consecutive readings.

Only about 2.1 ounces and is 7.75″ inches long.

Yes, the FDA requires the device be used only with single-use probe covers.

No. You’ll have to write the measurement down.

About 1200 tests. Contact us if you need more/extra batteries.
