Hans Heiss HRK-9900 Autorefractor Keratometer

Refractor & Keratometry Measurement

The Hans Heiss HRK-9900 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 allow 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 immediately.

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 determine a better contact lens fit.

Intuitive Diameter Measurement

Using the freeze function, the diameter of the cornea, pupil, or hard contact lenses worn by the patient can be measured.

Measurements are calculated by simply touching and dragging the screen with your finger.

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’ in the Potec PRK 7000

TFT-LCD with Touch Screen and Convenient control

Adopting a high-resolution VGA TFT-LCD with a Touch-Screen function, we 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 on the screen. Also, users can use the Key button as a convenient function.

Motorized Chinrest

The chinrest is motorized, and a switch conveniently positioned for the operator allows simple adjustment from patient to patient.

The motorized chinrest is easily controlled with a simple switch pressing up and down.


Instant Display Data

The built-in thermal auto cut-off printer can view or print results of up to 10 measurements stored in memory by simply touching the icon on the screen.

Interactive SETUP Change

Touch the icon on the screen to see the changed settings. The touch screen supports interactive setting changes quickly and conveniently, saving users time innovatively.

Assistant measurement function

The Hans Heiss HRK-9900 provides the assistant measurement function for the eyes, which have different measurements between the center of miring and the center of REF focus.

Guidance function for measuring

Hans Heiss HRK-9900 indicates the directions for focusing on the center of the measuring eye and shows the conditions for focusing for measurement convenience.


Printer with Auto Cutter Function

The Hans Heiss HRK-9900 immediately provides a complete printout of the measurement results, and an auto cutter is provided for convenience. There is the economy mode of printers, which saves printer paper by being well arranged and with amended letter sizes.

Data Transfer

Data can be transferred to external devices (personal computers, etc.) via an RS-232 interface. A USB interface is also provided for future compatibility. The user can send images of the patient’s eyes through the USB port and have the faster S/W upgrade by the PC program, which is provided as an option.

Tilting LCD for user

The 90° tilting LCD provides easy control by user standing or sitting on the Potec PRK 7000

Convenience stage-lock

Users can fasten the main body with simple control.
