Leave behind uncomfortable physical charts and evaluate your patients’ visual acuity and more with the latest in medical display technology, the Ezer EDC-BH digital chart. The Ezer EDC-BH LCD Visual Acuity Chart is a dedicated refraction device that provides precise and accurate visual acuities. The slim design facilitates wall installation and the modern 23-inch LCD monitor enhances the appearance of the office.
Multiple Test Charts
The EDC-BH is a 23″ medical monitor that comes equipped with all the charts necessary for most examinations. These include the Landolt ring chart, Fan and Block chart for Astigmatism, diversified ETDRS test chart, Color Blindness chart, Amsler chart, and much more. Additionally, the sharp colors of its full-HD TFT LCD screen (1920 x 1080) ensure accurate results in every test.
Astigmatism Test Chart
Tool used to detect and evaluate the presence of astigmatism through line patterns oriented in different directions.

Fan Charts and Blocks for Astigmatism
The incorporation of fan charts and blocks into the general astigmatism testing functions allows for a more precise evaluation of astigmatism.

Reverse Mode
All black-and-white optometric charts can be inverted to provide higher contrast, facilitating the evaluation of patients with conditions such as cataracts or who have undergone LASIK surgery.

Diversified ETDRS Optometric Chart
Letter and number-based charts recently added provide a wide range of diagnostic settings.

Amsler Vision Test Chart
Simple and effective tool used to detect and monitor alterations in central vision caused by macular diseases, such as age-related macular degeneration (AMD).

Enhanced Maddox Rod Test
The EDC-BH also features an integrated fixation target with ten brightness levels for the enhanced Maddox rod test.

Full-HD Video Playback
Images and videos can be easily loaded via USB or microSD card, allowing personalized content to be played during the consultation. This feature is especially useful for keeping children entertained while the professional speaks with the parents, enhancing the overall office experience. The system supports multiple video formats, including AVI, MPEG, MP4, and MKV, offering broad flexibility for multimedia content playback.

Various Color Blindness Test Plates
The system incorporates a variety of specialized plates for the detection and evaluation of color perception deficiencies. These tests allow the identification of different types and degrees of color blindness quickly and accurately, facilitating a more comprehensive assessment of chromatic vision during the visual examination.

Wide Range of Tests
The high-resolution LCD screen allows visual acuity testing across a wide range, from 0.05 to 2.0, ensuring sharp and precise optotype display.

Adjustable testing distance
Optometric charts automatically adjust according to the working distance set by the user, from 1.0 to 6.0 meters. This feature ensures that optotypes maintain the appropriate size for accurate visual assessment, easily adapting to different clinical spaces without the need for manual calculations or adjustments.

Enhanced R/G Filter Adjustment
The wide Red/Green adjustment range, with up to 96 configuration levels, allows the optometrist to optimize the screen display according to lighting conditions and the working environment. This improves the accuracy and reliability of binocular vision tests, ensuring more consistent results and a better patient experience.

CTRS Table Function (Contrast)
The CTRS function allows contrast sensitivity testing, evaluating the patient’s ability to distinguish letters or symbols at different contrast levels. This tool helps obtain a more comprehensive assessment of visual quality, especially in conditions where traditional visual acuity may not fully reflect the patient’s visual performance.

Customizable home screen and slides, up to 38 slides (Slide Function)
The slide function allows you to customize the home screen and load up to 38 slides or presentations, adapting the equipment to the needs of each practice. This option makes it easy to display educational content, visual instructions, or personalized material to enhance patient communication and deliver a more professional experience during the consultation.

Remote Control
The EDC-BH is operated via a specially designed infrared remote control, which provides quick and easy access to the multiple display settings. Users can adjust parameters such as the automatic power-off timer for energy saving, confirmation sounds, slideshow playback interval, and other functions, optimizing system performance according to the needs of each practice.

Mask Function
Vertical and horizontal masking functions allow the professional to precisely direct the patient’s attention toward specific areas of the visual test. This tool facilitates the controlled evaluation of individual optotypes or lines, improves patient concentration, and contributes to obtaining more accurate results during refractive and visual acuity examinations.

Compatible Multi-System Connection
The EDC-BH can be connected to various Ezer digital ophthalmic instruments to serve as the operational hub of the digitized examination office. Data can be entered or transferred directly from compatible devices, and the control unit can operate many of the different functions of each device.

DIGITAL CLINIC

What is an EMR?
Electronic Medical Records, commonly abbreviated as “EMR,” are a technological tool widely used in modern medical practices. EMR systems were designed to replace obsolete paper-based record-keeping methods and to optimize the collection and tracking of patient data over time. EMR platforms integrate the various components of a physician’s office visit, including admission demographic data and medical history, prescription information, laboratory data, practice management software, examination notes, and more. In general, EMR systems are used to promote economic efficiency and improve patient care through seamless coordination of data collection and storage. EMR platforms also increase patient transparency through the use of portals where patients can view important results and communicate with physicians securely.
In the ophthalmic industry, EMR are more important and popular than ever. The ability to store critical laboratory data related to prescriptions and diagnoses, while maintaining quick access to that information, is key to reducing consultation time and improving patient outcomes and satisfaction. With Ezer Digital Practice, sharing information is easier than ever! The Lensometer ELM-BH, the Autorefractor ERK-H/BH, the Phoropter EDR-H, and the Visual Acuity Chart EDC-BH interact via Wi-Fi to optimize communication between your preliminary testing and examination rooms.

We know it can be intimidating to introduce new technology into your practice, but with Ezer Digital Practice equipment and the superior technical support of US Ophthalmic, your practice will save time and money with seamless EMR integration.
