Accurate applanations produced through manual, easy alignment. Simple and smooth operation requires minimal training.
Air nozzle requires periodic cleaning. CRT display is older technology susceptible to screen burn.
Despite an older interface/display, the CT-80 is accurate, and fairly easy to use despite manual operator alignment.
The only thing worse than an air-puff to the eye is poor patient flow because your practice’s tonometry isn’t efficient. We don’t pretend to think NCT puff technology is refined, nor should you pretend that your patients enjoy this– they don’t. But we realize that air-puff IOP procedures are a necessary evil for a well performing practice, and your patients will understand this if it’s explained properly. Yes, there are other less invasive tonometry options out there, but all of them still make some form of uncomfortable contact with the eye, and all of them are less efficient than an NCT. Therefore, even though we dislike being “puffed,” we don’t dislike the CT-80 from Topcon. In fact, it’s the most widely used NCT in the world and in a market segment with few honest competitors; not to mention a fabulous price point (at least from us)– so we’re all forced to like it. Even Topcon knows this, and it must be the primary reason they haven’t released a new non-contact tonometer since the CT-80; a unit that still utilizes a CRT monitor designed in the mid-2000s. Regardless, the instrument is one of the best tonometry options we have. It’s quite easy-to-use (especially when compared to competitors) with its self auto-fire measurement and sensors which instruct the operator’s maneuvering for the optimal application moment. Measurements are well within standard deviation of a Goldmann, and the unit is fairly robust considering it must compress air within.
