Among all instrument categories, pachymetry has become the most compact and portable ophthalmic device category in existence. In the course of 10 years, pachymetry has gone from a desktop unit to a device smaller than your cell phone. However, we’re not sure that’s all a good thing. While handheld pachs certainly have more power and are easier to hold, they’re almost too small and constantly seem in danger of falling off the table. Regardless, Pachymetry utilizes basic ultrasound technology that hasn’t evolved in correlation to its size. This 50mhz probe is enough to get the job done with basic pressure– and the software interprets it accurately. 

OUR TAKE: Buy this if you do pachymetry on occasion but not enough to justify a brand new $3,000 PachPen.

#1. Rechargeable, Portable Enough

Although the Corneo-Gage Plus does require a nightly charge, the battery is ready to go for 30 patients throughout your day. We were slightly annoyed that the model will not allow operation while the device is being charged, however that’s not a big deal if you charge nightly (or whenever you’re planning on using it). We also enjoy the absence of a foot pedal, and the fact that there is no power cord– something rather advanced for a pachymeter of this type.

#2. 50 MHz with 1000 Echoes

The Sonogage’s 50MHz probe sends out 1000 ultrasonic echoes per reading, which is enough to retain an average reading within +/- 5 microns. It does require a small learning curve to realize just how hard you’ll need to press, however the Corneo-Gage is easy to use with most patients.

#3. Automatically Calibrated, For Life

In almost all cases, the Corneo-Gage 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. Upon occasion (about every decade) the power supply will fail, and it will require a simply, inexpensive repair. However, if you call Sonogage directly they will tell you that this is a lengthy repair process and it requires they’re facility to calibrate it. This simply is not true. The device’s calibration software is not located in the power supply box– if it were, the software calibration would become defective every time you turn it off. We don’t like when manufacturers lie to us, however given the device is actually more robust than they lead on is a-okay.

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 and the Corneo-Gage Plus is rather forgiving.

No. The Corneo-Gage offers “real-time readings” which averages many reading “echoes” into one reading. The unit can store up to 100 readings, however does not average all of them together on the machine itself.

It should last throughout the day (30 patients) however we recommend charging it every night.
