Huvitz Autorefractor / Keratometer HRK-9000A

Huvitz Autorefractor / Keratometer HRK-9000A

Huvitz HRK-9000A Autorefractor Keratometer provides an objective measurement of the refractive error and prescription for glasses or contact lenses. 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.

Zernike Topographic Map Support
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.

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

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 con-tact 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 accu-rate 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 commu-nication between examiners and examinees.

Auto Cutting Printer
Embedded printer allows to print 10 measure-ment 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 avail-able for data transmission with previous models.
