Ezer Autorefractor Keratometer ERK-770
The ERK-770 Auto Refractometer Keratometer is a next-generation device designed to deliver fast, precise, and fully automated measurements for refraction exams and corneal curvature analysis. Developed as an evolution of previous models, this system integrates advanced technology to optimize clinical efficiency and enhance the experience for both the operator and the patient.
Thanks to its automatic binocular positioning system with an integrated camera, the device can quickly and accurately locate both eyes, significantly reducing examination time. Additionally, its motorized rotary prism technology ensures faster and more stable measurements by capturing multiple data points, improving the overall accuracy of the results.
The ERK-770 features a fully automatic measurement system that minimizes operator intervention. With auto-alignment, auto-focus, and auto-capture, the device streamlines the examination process, reducing workload and improving workflow efficiency in busy clinical environments.
Equipped with a high-resolution camera and binocular tracking technology, the system automatically detects and aligns both eyes. This ensures accurate positioning and significantly reduces measurement time, making it ideal for high-volume practices.
Using a motorized rotary prism system, the ERK-770 captures multiple data points quickly and accurately. This technology enhances measurement stability and provides highly reliable results for both refraction and keratometry.
This dual-function device integrates autorefractometry and keratometry into a single unit, enabling practitioners to accurately measure key parameters such as sphere (SPH), cylinder (CYL), axis (AXIS), keratometry readings (K1 and K2), and pupillary distance (PD). By combining these essential diagnostic capabilities in one system, it eliminates the need for multiple instruments and helps optimize clinical space while improving workflow efficiency.
The device is equipped with a 10.4-inch color touchscreen that offers intuitive navigation and easy operation. Its tiltable and reversible design allows flexible positioning, improving ergonomics for both seated and standing use.
With rapid measurement speed and minimal manual adjustment, the ERK-770 ensures a smooth and comfortable experience for patients. The automated system reduces examination time while maintaining high accuracy.
The system supports multiple connectivity options, including USB, Wi-Fi, Bluetooth, and optional 4G, enabling seamless data transfer and easy integration with EMR systems while ensuring efficient and streamlined record management.
An integrated high-speed thermal printer provides immediate printouts of measurement results, enhancing workflow efficiency and patient communication.
The ERK-770 is suitable for a wide range of professional settings, including optical shops, ophthalmology clinics, hospitals, and vision screening programs. Its combination of automation, precision, and speed makes it a versatile and reliable solution for diverse clinical and diagnostic environments.
The ERK-770 Auto Refractometer Keratometer delivers a powerful combination of automation, accuracy, and efficiency. It is an excellent choice for eye care professionals seeking to optimize their diagnostic capabilities and improve patient throughput without compromising quality.
