Tomey Optical Biometer OA-2000
Experience fast, precise, and fully automated biometry with the Tomey OA-2000. With just one touch, the system begins capturing all key measurements—thanks to advanced 3D eye-tracking technology and Fourier-domain optical coherence. From axial length, ACD, lens and corneal thickness, to topography and white-to-white distance, the OA-2000 delivers reliable data, even through dense cataracts. Designed for effortless IOL power calculations, toric planning, and seamless workflow integration, it sets a new standard in non-contact ocular measurement.
Advanced Optical Biometer with the Latest Technology
The TOMEY OA-2000 Optical Biometer delivers fast, precise, and comprehensive refractive measurements by integrating topography, axial length, lens thickness, and pachymetry—creating the ideal dataset for advanced ray tracing. This powerful combination ensures excellent IOL predictions, even in challenging eye conditions or toric IOL cases. With a single measurement, it captures biometry of the entire eye, including ACD, pupil diameter, and white-to-white distance. Designed for superior usability, the OA-2000 offers outstanding optical results, perfect K values for optimal toric outcomes, and the advanced Hill-RBF method for exceptional post-refractive accuracy. Its open data system, intuitive interface, and quick access to full eye data ensure improved refractive outcomes and precise targeting—every time.
Fourier domain method and Ring cone method
Leveraging advanced Fourier-domain technology, the Tomey OA-2000 offers exceptional tissue penetration, enabling high-speed, high-resolution scans—even in patients with dense cataracts or other challenging ocular conditions. Its integrated Placido-disc–based topography ensures highly reliable K values, which are essential for toric IOL planning and post-refractive assessments. The system uses the ring cone method to measure the radius of corneal curvature at ø2.0 mm, ø2.5 mm, and ø3.0 mm, enhancing precision in corneal mapping. In rare cases involving extremely mature lenses, the AL-4000 handheld ultrasound device can be used as a complementary tool, seamlessly communicating with the OA-2000 via Bluetooth.
Optical Measurement Mode
The Optical Measurement Mode of the Tomey OA-2000 provides a fast, non-contact, and highly accurate method for acquiring essential biometric data in a single operation. Using advanced Fourier-domain technology, this mode allows for simultaneous measurement of five critical parameters, streamlining the diagnostic process and enhancing efficiency in clinical workflows.
