The Canon TX-F is like a rare exotic bird we stumble upon occasionally, and whenever we do we sit back and admire its three-dimensional automated system, unique design, and peculiar software features. All Canon ophthalmic instruments are underrated and were, back in the day, far beyond their time. The TX-F is no exception, and utilizes similar design and user-interface design that Canon’s other pre-test instruments do, combined with IOP tonometry features that set it apart from its NCT competition. Before we dive-in to the TX-F’s fully automated tracking system, it’s worth mentioning that the actual operator controls are (in our opinion) superior to the traditional joystick. The operator trackball, combined with elevation scroll almost make the automated system seem unnecessary- it’s incredibly smooth, easy, and fast to obtain a measurement all with manual controls. Remarkably, you’ll (almost) never need to thanks to Canon’s three-dimensional automated tracking system, which seamlessly finds the proper axis alignment of the pupil and automatically fires the puff. There are other machines that automatically locate the pupil (see Reichert AT550), however not as fast and as foolproof as the TX-F. Occasionally, on some uncooperative patients whom seem to blink 100 times per minute, the automated capture may result in a false measurement; thus the manual controls are there to recapture. Additionally however, the TX-F will also take a snapshot of the eye given a poor reading, providing the information you need to make a correction. At a glance, you’ll  know whether it was an eyelid, eyelash or the eye being out of position that caused the error. An error message will tell you what action to take- such as adjusting the chin rest or optical head.

#1. An Arcade Of Absences

Look again, the AT-550 has no such chin rest, joystick, or viewfinder camera to speak of. Something that may seem rather odd for a non-contact tonometer relying on proper distance and alignment. Yet instead of the NCT being reliant on you doing all the work, the self-contained AT-550 captures accurate IOPs with just the touch of a button. Once the patient has his/her forehead against the rest, the unit automatically finds the eye, aligns its axis’, and captures a measurement all without interference. It resembles less of a typical pretest instrument and more like an arcade video game.

It does have RS-232 connections outputs, however it will depend on your EHR company and whether they’ve offered the gateway for such device.

Yes. The unit will take the average of multiple measurements of each eye respectively, and produce them on the print as well.
