Huvitz Autorefractor / Keratometer HRK-1

The optical system ensures precise measurements
Huvitz Smart Assembly Moving Control Technology
The invisible technology behind Huvitz’s REF optical system is evident in the precision and stability of measurement results. Considering the patient’s refractive error, the measurement ring is projected onto the retina and automatically adjusted via Smart Assembly Moving to ensure a stable signal.
The HRK reduces the effect of irregular light reflection in normal and cataract eyes, resulting in more precise REF (refractive power) data.

Virtual Fixation Target Quick Function
The Fixation Target quickly guides to easily find the patient’s visual apex from any position, allowing agile alignment. Subsequently, the REF refractive power data is automatically obtained with reliability.

Simple Up and Down Auto-Tracking
The auto-tracking system follows the patient’s eye, facilitating measurement by allowing the joystick to be manipulated forward and backward, without the need to rotate it.

More Precise Measurements, Prescriptions and Adjustments
Refractometry (REF Mode)
Mode designed exclusively to measure refractive power.

Keratometry (KER Mode)
Mode designed exclusively to measure corneal curvature.

K&R Mode
Mode that continuously measures corneal curvature and refractive power.

Real-Time Color Display Mode
This mode uses a color camera and white LED light for color visualization, general condition monitoring, contact lens fitting, and prescription. It offers on-screen color visualization through a yellow filter, white LED, and blue LED to observe the corneal curvature radius when contact lenses are used.

Color View Mode Indicator Display (Yellow Filter)
Image processing with fluorescein solution and yellow filter automatically determines the adjustment status.

Color View Mode Indicator Display (White LED)
This function uses white LED illumination to provide a color observation image.

Color View mode indicator display (blue LED)
This function observes the cornea and the contact lens fitting degree using fluorescein solution and blue LED.

Practicality for Prescribing Contact Lenses
The HRK-1 automatically calculates and displays the Base Curve value for RGP lenses, adjusting and capturing the image contrast observed through On-K adjustment based on the measured KER data.

Sharp Retroillumination Mode
This mode allows observation of ocular health and conditions, such as lens opacity or corneal damage. SPH, CYL, and AXIS data, required for eyeglass and contact lens prescriptions, are obtained simultaneously.

SIZE Mode
Mode designed specifically to measure pupil diameter.

DISPLAY Mode
Measured results stored in memory are displayed.

Usability and Efficiency, Designed Based on Our Users’ Experiences
7-Inch Color Touch Screen
Featuring a wide TFT LCD color display, it delivers high-quality images with a chip design for real-time processing. The touch screen, free of buttons, is as familiar and convenient as a smartphone. Enhanced optical magnification allows the eye to be observed and measured in greater detail, providing larger and sharper images.

Secure Deletion Confirmation Dialog Box

The deletion confirmation feature prevents data from being immediately erased after measurement, allowing for subsequent analysis.

High-Speed Printer and Convenient Paper Change
The HRK-1 prints 10 measurement results quickly and silently in less than 3 seconds. It also features an easy and convenient paper change function.

Connectivity and Efficient Diagnostic Management with HRK Mate
With the HRK Mate software, you can connect the HRK-1 to a computer and manage all patient diagnostic results in a single consultation.

Seamless Integration
The HRK-1 Autorefractor can be perfectly connected to the HLM-1 Lensmeter, Digital Refractor, Optotype Projector, and LCD Screen via RS-232 cable. This integration increases the efficiency and precision of the diagnostic process by enabling easy data transfer and synchronization between devices, ensuring an optimized workflow and improved patient care.
