Compact All-in-One Design

The ETR-770 was carefully engineered to consolidate multiple diagnostic functions into a single compact workstation. By integrating the phoropter, the optotype system, and the control interface into a single unit, it eliminates the need for bulky equipment and large examination rooms. This makes it especially valuable for optical shops, small clinics, and high-volume environments where space optimization is essential. Despite its compact size, the system delivers a complete professional refraction experience comparable to traditional configurations.

Refraction anywhere

Advanced Display and Control System

To ensure accurate diagnostics, the ETR-770 incorporates a high-resolution display system featuring LED illumination and a 5.7-inch color LCD touchscreen. This delivers clear, bright, and consistent images, allowing patients to easily identify optotypes while enabling precise evaluations by eye care professionals. The display quality enhances both the reliability of the examination and the overall patient experience, reinforcing confidence in the results. Ergonomics plays a fundamental role in daily operation. The main control dial, equipped with an integrated S / C / A mode key, allows for quick and smooth adjustments of refractive values, enabling professionals to work with precision and efficiency.

Sophisticated Digital Phoropter

Designed with a modern and refined ergonomic structure, this phoropter enhances both comfort and efficiency during examinations. Its carefully developed design reduces operator fatigue while providing a more relaxed and comfortable experience for patients, without compromising clinical precision.
Developed to deliver accuracy and performance, the system provides fast, smooth, and virtually silent lens transitions. This allows professionals to make fine prescription adjustments effortlessly, with the press of a button, ensuring a continuous workflow and an enhanced patient experience.

Advanced Optotype System

The ETR-770 incorporates a comprehensive digital optotype system, designed to support a wide variety of visual acuity tests. It includes multiple optotypes, such as rotating E, letters, numbers, and pediatric charts, as well as specialized tests including cross cylinder, astigmatism evaluation, red/green balance, Worth 4-dot test, and fixation points. With a total of 33 chart options available for near and distance vision testing, professionals have the flexibility needed to perform precise, personalized examinations tailored to each patient’s needs.

Intuitive Operation

The symmetric, clean, column-free design allows continuous examinations from both the right and left sides of the patient. This enhances workflow flexibility and enables multiple ETR-770 units to be efficiently arranged in various clinical configurations. Designed to accommodate any examination preference, the ETR-770 supports both seated and standing positions. Its ergonomic versatility ensures comfort for the clinician while maintaining consistent precision across all measurement methods.

Flexible Installation

Unlike traditional refraction systems that require large spaces, the ETR-770 offers exceptional installation flexibility. The system supports an adjustable optical distance of 0.1 to 2 meters, simulating a standard testing distance of 5 meters. This allows installation in space-limited environments without compromising diagnostic accuracy. Whether in a compact commercial setting or a mobile clinic, the ETR-770 easily adapts to different configurations and operational needs.

Cloud Connectivity and Remote Refraction

The ETR-770 was developed to meet the needs of modern connected ophthalmic care environments through advanced cloud integration and built-in Wi-Fi connectivity. Leveraging an advanced architecture, multiple devices can be seamlessly connected within a unified network, enabling centralized management and real-time communication across different locations. This connectivity allows professionals to remotely access and control the refraction system from virtually anywhere. Optometrists can conduct examinations without being physically present at the practice, communicating with patients in real time through integrated audio and video features. This not only increases efficiency, but also allows a single specialist to serve multiple units simultaneously.

Flexible Operation Modes

The ETR-770 offers operational flexibility in two modes. Professionals can operate the system directly from the local control panel or remotely via dedicated software, ensuring adaptability to different workflows and practice models.

Connect Everything. Work Smarter

Two built-in RS-232 ports allow the ETR-770 to connect directly to an autorefractor and a lensometer, creating a faster and fully integrated diagnostic workflow.

The Ezer ETR-770 is an ideal solution for optical practices looking to optimize their use of space, ophthalmology clinics interested in modernizing their diagnostic capabilities, and optometry offices seeking to improve their workflow and increase patient throughput. It is also particularly well-suited for telemedicine services and mobile vision care units that require compact, versatile, and high-performance equipment.

Thanks to its innovative design and remote refraction features, the ETR-770 easily adapts to both traditional vision care models and emerging digital health trends, offering flexibility, efficiency, and a superior experience for practitioners and patients alike.
