PRK-5000 - Potec


Reflection sight/Measurement of cornea curvature

PRK-5000 provides wide reflection sight from -25.00D to +22.00D. And cornea curvature measured from 5.0mm to 10.2mm. You can check your reflection sight and cornea curvature at once with easy and friendly operation and confirm results at once, too.

CLBS(Contact Lens Base Curve)

It can be measured by back side contact lens holder which is modeling of hard contact lens' base curve (the rear curve), checked lens and distinguished from right-left changed lens.

Measurement of diameter

Used PRK-5000's picture suspension function, it can be measured cornea, the pupil diameter and hard contact lens which have damaged from users. It can make stopping the eye's reflection, so the procedures are convenient and precise.

Auto PD Measurement

It can measure and indicate pupils' distance automatically by using measurement of reflection eyes.
Auto power saving If PRK-5000 is not used over 5 minutes, it shut off from electric currents of lighting circuit and TV monitor by built in power saving function. It can extend machinery's life by protecting heat genesis from electronic circuits and save energy.

Colored picture notice table

A wide visual field angled color picture notice table makes easy to fix patients' eye through making patients comfortable. An auto cloud and mist function is helpful to children or damaged eyes because it affects to machinery near vision and patients control.

Direct results indication

It can be seen measurement results saved in memory at monitor (Maximum 10 to an each eye). And also it can print with a built in printer.

Operation layer

We produce compact operation layers with innovative design and advanced technology. And it contains a power sign light and a fixed gripe of stage.

Easy handling joystick

PRK-5000 adopts convenient omnidirectional joystick. It is executed aim and measurements by one hand. Novices gain precise results every time.


When you push just "PRINT" button, PRK-5000 provides perfect prints of measurement results immediately. It places PRk-5000's front-right side for users' convenience.

Transmission of data

Measured results can be transmitted to external tools (PC, etc) using RS-232.
