Advanced pachymetry software with a focus on pre-op, 256 data points result in accuracy, responsive touch-screen.
Dot-matrix touch screen feels dated; hard to see from some angles, not exactly as portable as they make it sound.
The Sonomed 300p is an impressive advanced surgical-focussed pachymeter that lacks some portability compared to other pachymeters.
With all of the small pen-like pachymeters available, its hard to imagine a unit nearly 9.4″ inches in width. Yet here we are testing the Sonomed 300P– on a table of course, because that is the only place it can safely rest. Sonomed claims that the 300P is ‘portable’ however I’m not really sure where in your lap it’s supposed to sit while you’re making contact with the cornea.The 300P however is more advanced than all of those other handheld units, and there is something to be said for a larger desktop display. But oddly enough the 300P’s screen is in some kind of analog text that is practically invisible from any awkward operator position. The display’s touch screen is efficient and responsive enough however the ‘matrix grid’ layered on the screen (that react to your touch) feels dated. If the operator peers directly at the screen this is however not a problem and Sonomed’s software is impressive. The unit’s multiple corneal maps provide a graphical display of different areas on the cornea, and thanks to 256 individual measurements and an automatic measurement algorithm you’ll be sure to trust it. It’s definitely a more surgically inspired pachymeter than most we see in the handheld or even compact form.
