Huvitz HRK-9000A

Combining Everything into One
All New HRK-9000A Auto Ref / Keratometer
Unceasing efforts for higher accuracy lead to objective refraction followed
by standardized subjective refraction with HRK-9000A and in the end,
unprecedented accurate results wait for you.
HRK-9000A speaks no compensation, but perfectionism in refraction
composed of glare test, superior contrast sensitivity and TFBUT/Meibography
which are introduced for the first time in the world.
A beautiful curvilinear design speaks emotional stability in you.
With HRK-9000A, take satisfaction which you have ever enjoyed before

Subjective VA Test
Comparison between subjective and objective VA tests yields more reliable and accurate data.
Subjective VA test is useful in deciding necessity of progressive lenses because it checks visual
acuity based on patients’ responses.

Contrast Sensitivity and Glare Test
Highly reliable night visual acuity is examinable with low contrast sensitivity test and glare test which perfectly reproduces halo effect.
Progress after refractive or cataract surgery can be monitored effectively.

TFBUT Measurement and Meibography
Conditions of tear film and dry eye can be collected by TFBUT(Tears Film Break-Up Time) are readable
for thorough understanding of visual acuity. Degeneration of meibomian gland can be also
monitored with enough light source and image enhancement function.

Wavefront Technology
Huvitz’ wavefront analysis algorithm goes beyond general refraction to conclude highly accurate
and reliable cornea refractive power and index. Wavefront technology measures the wavefront of
light reflected from the retina and the refractive power with various sensors divided by sectors
and analyzes them with extreme precision.

Micro Lens Array
Huvitz’ own developed Micro Lens Array creates a number of separated focal spots, of which the
pattern provides valuable information of patients’ ocular systems.

More Accurate Data
Accuracy of KER data is improved by setting optimal zone diameter on measuring spot and
also REF data by standardization of quantity of light of fogging chart and fogging lens position
along with complete block of accommodation.

Color View Mode
Full color CCD camera and white LED light source in auto ref / keratometer enable you to see
eyes and contact lens fitting status which was previously only possible with slit lamps.
Subjective VA Test – Glare Mode

Peripheral Keratometry Measurement
Continuous measurement on periphery of cornea at 90° both vertically and horizontally from center
of cornea produces curvature and eccentricity values of all points and allows best fitting of contact lenses.

IOL Mode
Extra measurement mode is available for IOL power or visual acuity after cataract surgery.
Iris and Pupil Diameter Measurement Image capturing function supports highly accurate
exam by measurement of iris and pupil diameter with diameter from 2mm to 14mm.

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.

Efficient Contact Lens Prescription
Image capture and contrast regulation are possible. HRK-9000A gives you the best On-K fitting guide
based on the base curve and KER value.

Touch and Tilting 7” Color Display
Wide color TFT LCD supports high-resolution images and real-time image processing to realize
afterimage-less image quality. Moreover, swiveling and tilting touch display is
readable from any direction for smooth communication between examiners and examinees.

Auto Tracking
Cutting edge auto sensor and 3 dimensional movement mechanism allow you to track down a
measuring focus of an eye automatically and complete measurement perfectly even with inexperienced users.

Auto Cutting Printer
Embedded printer allows to print 10 measurement data within 3 seconds without noise at all.
Replacement of paper roll is in one-touch action.

Wireless Communication
Wireless Communication via Wi-Fi allows perfect data transmission with HDR-9000 and HLM-9000
regardless of working environment. Classic communication via RS-232 cable is available
for data transmission with previous models
