PIROP
PIROP is a modern ultrasound corneal pachymeter with biometry function, using for the first time the ultra high 400 MHz sampling frequency, giving the users new idea of superb accuracy and repeatability.
Key advantages:
- Full measurement diagnostics of all kinds of eye
- Very high accuracy and repeatability of measurement
