POTEC PRK-9000 Auto Ref-Keratometer | Advanced Eye Exam Equipment

Description

3D/2D Semi Auto Pupil Tracking: The three/two-dimensional automatic eye detection and focusing
mechanism enables eortless and precise refractometry (-30D ~ +25D)
and keratometry (5.0mm ~ 13.0mm) measurements, powered by
advanced algorithms and a high-speed image processor.

Pre-Dry Eye Syndrome Observation: Meibomian gland dysfunction is a primary contributor to dry eye syndrome.
The PRK-9000 employs infrared imaging technology to obtain high-contrast
images of the Meibomian glands, facilitating the early identication and
monitoring of pre-dry eye syndrome resulting from gland dysfunction.

Color View Mode: The integration of a new color camera and LED lighting facilitates the examination of primary ocular
conditions, including cornea, iris, pupil and etc.

Connectivity: Seamless integration is essential for versatile device usage in various settings. The
PRK-9000 is equipped with RS-232C, Wi-Fi, and LAN connectivity, ensuring universal
compatibility with standard platforms.

Near Vision Simulation: The necessity for progressive lenses can be evaluated through the "Near Vision Simulation." Upon
completion of a refractive measurement, additional diopter power between +0.00D and +3.50D can
be administered in increments of 0.25D or 0.50D, allowing for a comprehensive analysis of
presbyopia.
