Product Description

Huvitz HRK-8000A Autorefractor Keratometer Aberrometer provides outstanding measurements for a precise diagnostic.

You can customize lenses, play a more active role in managing cataract and refractive surgery patients and more with the HRK-8000A. The HRK-8000A combines the features of an auto refractor, auto keratometer, and wavefront aberrometer into one, high-tech instrument. The HRK-8000A generates a Hartmann-Shack based Zernike wavefront map that details the refractive errors as well as the lower- and higher-order aberrations. The HRK-8000A also features point spread function, image simulation and the world’s first contact lens fitting function ever to be made available in an autorefractor / keratometer.
Features of the HRK-8000A

Optimized Optical System
A wavefront is a physical representation of the optical quality of a light beam. Using various methods, aberrometers map how light rays travel through the eye. The HR-8000A is engineered according to the Hartmann-Shack wavefront measurement technique, which is widely preferred for its speed and repeatability.

Micro Lens Array
In the HRK-8000A, high-resolution mapping is achieved using a micro lenslet array, which was developed by Huvitz.

Customized Lens Manufacturing
High order aberration and Zernike map data output function allow premium custom spectable or contact lens manufacturers to improve vision accuracy and power.

More Data on Aberration Measurement
High order aberration data such as Coma, Trefoil, Spherical Aberration, Secondary Astigmatism, and Tetrafoil is available with the Huvitz HRK-8000A. Clinical usage of this data is all in your hands!

High Order Aberration Map
Besides the conventional data such as Spherical, Cylinder and Axis, the high order aberration data is displayed in a graphical Zernike refraction map for superior clinical decision-making.

PSF & Image Simulation
Point Spread Function (PSF) and chart simulation of retinal display helps patients better understand their vision and the benefits of customized lens benefits.

Color View Mode!
The Full Color CCD camera and white LED light source offer views previously only possible with slit lamps.

Peripheral Keratometry Measurement
The HRK-8000A provides peripheral keratometry measurements that will aid in contact lens fittings. El HRK-8000A permite realizar mediciones de la queratometría periférica que facilitan la adaptación de las lentes de contacto.

Ultra High Precision KER Data
Mire ring and LED sources enable highly reliable keratometry data of the corneal base curve to be obtained.

Contact Lens Fitting Assistance Guide
The world's first contact lens fitting function in an auto ref-keratometer enables you to see fluorescein liquid with blue illumination. The HRK-8000A also analyzes and simulates the lens fitting status with automatic calculation and recommendation.

Contact Lens Prescription Guide
Image capture and contrast regulation is posible.
The HRK-8000A gives you the best On-K fitting guide based on the base curve and KER value measured!

Touch & Tilting Color Display Screen
A bright, high contrast 7" VGA color TFT LCD screen provides high resolution video images. A smooth, free tilting function also offers you a comfortable and clear view at any angle.

Auto Tracking
The cutting edge auto sensor and 3 dimensional movement mechanism enables you to track down a measuring focus of an eye automatically and complete the measurement perfectly even with an inexperienced user.
Animated Guide
In case a measuring point is out of auto tracking range, the animated guide on the screen suggests how to operate the joystick in the easiest and most intuitive way.

Vision Comparison Function
The internal chart provides a vision comparison fucntion of current vision and corrected vision.

Motorized Chin Rest
Just by pressing the Up & Down buttons, users can set the height of the measuring point comfortably and quickly.

Faster Measurement Speed
Faster measurement speed than any other competitors' equipment!

Comfortable One Touch Lock
The upper moving stage can be locked easily with the one touch button, making locking smooth and easy.

Quiet & Speedy Auto Cutting Printer
Automatic paper cutting and one touch paper roll change functions are new advantages of the HRK-8000A.

Ext. Monitor & Network Connectivity
Full HD video output through the HDMI port provides a differentiated explanation base for clinical consult with your patients. The HRK-8000A supports network connectivity with Huvitz Digital Refraction System enabling a fast and easy refraction.
