Pachymetry isn’t new technology. It’s simple echo spike ultrasound techniques that map the cornea in its simplest form– by thickness. Although brand new OCTs may have pachymetry built-in, and handheld instruments seems to be all the hype, the Pachette 3 enters as a bare-bones simple alternative to all other options. It’s portable without being difficult to use (in the hand), it’s also well equipped with a 20mHz probe without being overly intimating. The button-touch interface is basic and so is most everything else– but after all, that’s what Pachymetry should be, right? If we had a complaint it would be the probe base itself given it’s a bit slippery if not washed free from oils- but we stand by our claim that it’s just as easy-to-use as anything else. In typical DGH fashion the probe produces just 20mHz of feedback power, which, compared to others currently on the market would seem weak, however it appears that newer technology does more with less. When compared to similar units such as the Sonogage Corneo-Gage Plus, which produces 50mHz of power, we see marginal to no effects of less mHz in the DGH.
