Auto Ref-Keratometer
Powerful Technology PRK-6000

▶ Touch Screen
▶ Motorized Chinrest
▶ Peripheral Keratometry

Refractoin & Keratometry Measurement
PRK-6000 provides an extensive dioptric measurement range (-25D to +22D), and the radius of curvature for keratometry is 5.0mm to 10.2mm. Easy alignment and friendly operation allows you to measure the refraction and keratometry in sequence, and the results can be validated immediately. Owing to its easy alignment and friendly operation you can measure the refraction and keratometry in a sequence, the results can be checked all at once.

Peripheral Keratometry
Peripheral corneal curvatures can be measured by having the examinee look at the peripheral eye fixation lamps. Measuring the corneal periphery will help you examine irregular astigmatism, and also determine a better fitting for a contact lens

Intuitive Diameter Measurement
Using the freeze function, measurement of the diameter of the cornea, pupil or hard contact lenses worn by the patient can be performed. By simply touching and dragging the screen with your finger
measurements are exactly calculated.

TFT-LCD with Touch Screen
By adopting high resolution VGA TFT-LCD with Touch Screen function, we virtually removed all input keys except the measurement button on the Joystick and Chinrest control switches. Tests are performed rapidly and conveniently by simply pressing a button or the icon indicated on the screen.

Instant Display Data
By simply touching the icon on the screen results of up to 10 measurements stored in memory can be viewed or printed by the built in thermal auto cut-off printer.

Interactive SETUP Change
Simply touch the icon on the screen and changed settings can be seen. The touch screen supports interactive setting changes quickly and conveniently saving user time innovatively.

IOL Measurement
When refraction results in an error reading due to an intraocular lens or cataract the measurement can be performed with the IOL icon switched ‘ON’

Motorized Chinrest
The chinrest is motorized with the use of a switch conveniently positioned for the operator. This makes for simple adjustment of the chinrest from patient to patient.

Data Transfer
Data can be transferred to external devices (personal computer, etc.) via an RS-232 interface. A USB interface is also provided for future compatibility.

Printer with Auto Cutter Function
Simply touch the “PRINT” icon on the screen and the PRK-6000 will immediately provide a complete printout of the measurement results. An Auto Cutter is provided for convenience.
