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.

OUR TAKE: Nice and basic/simple like Pachymetry itself. Buy this if you do Pachymetry on occasion but not enough to have it on another combo instrument.

Ophthalmic Ultrasound: corneal pachymetry.

*coverage of the above procedure may be subject to local reimbursement amounts and special provisions.

*based on CPT 76514 assuming determination of refractive state

#1. 25 Measurement, 1.6 Seconds

The Pachette 3 will store up to 25 measurements bilaterally, each measurement consuming 1.6 seconds given its 25mHz probe.

#2. IOP Correction Built-In

IOP corrections calculation is built directly into the software; displaying standard deviation and running average for each eye as well.

#3. Automatically Calibrated, For Life

In almost all cases, the Pachette 3 remains calibrated for its lifetime, regardless of event. We don’t recommend you drop it on the ground, however the device (and the probe) is a whole lot more robust than the company itself wants you to believe.

It shouldn’t be terribly difficult. Although numbing drops are required, and some moderate pressure must be applied to the front of the cornea, readings are relatively easy to acquire.

Yes it does. Displayed on the backlight LCD, the unit will display a running average.

The device does use batteries which may need to be replaced (or recharged) upon occasion.
