PIROP – Ophthalmic Scanner (A+P+B)


PIROP – state-of-the-art ophthalmic ultrasonic device for  Biometry , Visualization and Pachymetry of eyeballs   (A+B+P  Scan) – modified version.

A-SCAN Ocular Lens biometrics
Digital ‘A-scan’  tool for ophthalmology, biometry and lens power calculation of intra-ocular implants.

B-SCAN Eye examination
Modern  ‘B-scan’  tool for ophthalmology,  interior eyeball imaging, retina, optical nerve

PACHYMETER (P-SCAN) Ocular Cornea biometrics
Up-to-date ultrasonic pachymeter (corneal thickness biometrics) with a very high sampling frequency (400MHz)- a significant increase in measurement accuracy.

PIROP user’s interface based on touch screen technology makes operation easy and user-friendly. The touch screen can be also operated not only with fingers, but also using the enclosed stylus to keep it clean.
