Equipped with next-generation annular array probes, a high-resolution touchscreen, and seamless data communication via USB or LAN, the UD-800 delivers intuitive operation, speed, and efficiency. With its exclusive dual-ring 10 MHz B-Scan probe and high-precision A-Scan biometry probe included, this unit provides a solid foundation for advanced diagnostic performance. The intelligent software interface smoothly guides the user through all measurement procedures. Results can be printed via the built-in or an external printer, saved internally, or exported to a PC. Fully DICOM-compatible, the UD-800 integrates seamlessly into hospital networks or supports straightforward data export, offering complete flexibility for modern clinical environments.

Comprehensive Probe Selection for Versatile Diagnostics

The Tomey UD-800 includes a high-resolution 10 MHz B-Scan probe as standard, ensuring precise and detailed imaging. In addition, users can choose from four optional probes designed for specific diagnostic needs, allowing complete system customization to accommodate a wide range of clinical applications. This flexible probe configuration ensures that the UD-800 adapts perfectly to the unique requirements of each practice.

10 MHz 2-Ring Array B-Scan Probe

The Tomey UD-800 10 MHz 2-ring array B-Scan probe delivers high-resolution imaging with optimized wide-field tissue penetration, ideal for posterior segment evaluations. With a frame rate of 20 fps, 131 acoustic lines, and 256 gray-scale levels, it provides smooth and detailed visualization. Its wide imaging range (up to 48.0 mm / 52°) and measurement accuracy (±0.5 mm) ensure reliable diagnoses. The probe supports fine measurement steps (as small as 0.055 mm) and offers a lateral and axial resolution of 0.6 mm. Designed for enhanced safety and comfort, it features a direction marker and is compatible with wiping or immersion disinfection up to 10 mm from the tip. This probe is a key tool for precise and efficient ocular evaluations.

Clinical Cases (10 MHz B-Scan probe with 2-ring array)

Optional A-Scan Diagnostic Mode

The UD-800 offers an optional A-Diagnostic probe for A-Mode diagnosis, enabling the detection of abnormal tissue characteristics through waveform analysis. This feature allows clinicians to evaluate and differentiate ocular structures by observing amplitude peaks that indicate pathological changes. It is a highly valuable tool for detailed assessments beyond standard biometry, particularly in complex diagnostic cases.

Biometry Module with Advanced IOL Power Calculation (Optional)

The biometry module of the UD-800 is a precise and efficient tool designed for accurate ocular measurement. It works by transmitting ultrasound waves to the eye through a 10 MHz solid-state probe with an integrated red LED fixation light, capturing the echoes reflected at the various tissue interfaces. The time it takes for the ultrasound to travel from the corneal surface to the target tissue is measured and, using preset acoustic velocity values, the instrument calculates the length of the ocular structures with a measurement range of up to 45.00 mm, a resolution of 0.01 mm, and an accuracy of ±0.1 mm. The system includes a powerful intraocular lens (IOL) power calculation function that supports multiple formulas, including Haigis (standard and optimized), Hoffer® Q, Holladay 1, SRK II, SRK/T, SRK SHOWA, Shammas-PL, and SRK/T Double K. These options ensure optimal outcomes for both standard cataract surgery and post-refractive surgery cases. With this comprehensive feature set, the biometry function of the UD-800 provides all the essential data needed to support safe intraocular lens power selection.

Pachymetry Mode – Precision in Corneal Thickness Measurement (Optional)

El Tomey UD-800 features a high-precision pachymetry mode utilizing a 20 MHz solid-state probe with a 1.5 mm tip at 45°, designed for accurate corneal thickness measurements. It offers a measurement range of 150–1,500 μm, a resolution of 1 μm, and an accuracy of ±5 μm, making it ideal for refractive surgery planning and glaucoma evaluation. The system supports adjustable speed settings and advanced bias analysis, ensuring reliable results across a wide range of clinical conditions.

Pachymetry Mode – Precision in Corneal Thickness Measurement (Optional)

The optional 40 MHz UBM probe for the Tomey UD-800 delivers high-resolution imaging of the anterior segment without the need for a water bath, thanks to its waterproof disposable membrane cover. This innovation enables fast and comfortable examinations, even with the patient in an upright position. It facilitates detailed visualization of the posterior iris, ciliary body, and filtering bleb structures, making it particularly valuable in the diagnosis of narrow- or closed-angle glaucoma.

Database and Data Export

The UD-800 features intuitive software that efficiently manages all measurement results. Reports can be printed via the built-in or an external printer, and data can be saved directly to the internal database or to a USB drive, with a capacity of up to 52,000 ocular records on a 32 GB unit. Furthermore, DICOM compatibility ensures seamless integration with hospital networks, while CSV and JPEG export options provide flexibility for data sharing and analysis.

Video Function

The UD-800 is equipped with a video mode that allows real-time recording and playback directly on the device. This feature not only optimizes the diagnostic process —helping to reduce examination time— but also enhances communication with patients, supporting informed consent. Each eye examination can store up to 200 images when using the 10 MHz B-scan probe. The playback controls allow smooth video review, including frame-by-frame forward and backward navigation. While a video is playing, a “Stop” button is displayed for immediate control, ensuring precise observation and documentation.
