Description
The SBM Sistemi OS1000 is a noninvasive corneal topographer designed to acquire and analyze corneal-surface measurements and ocular-surface parameters. It generates objective maps, numerical measurements and clinical images to support qualified eye-care professionals in anterior-segment assessment.
Its 24-ring Placido system captures 8,640 measurement points across a published corneal coverage of 10 mm. The software provides multiple presentation and analysis modes, including comprehensive and single maps, 3D visualization, elevation analysis, aberrometry, simulated visual acuity, contact-lens fitting, differential maps and examination comparison.
In addition to corneal topography, the OS1000 can be configured with ocular-surface and dry-eye examinations. Depending on the selected Plus or Full software version, these functions may include interferometry, automatic NIBUT, meibography, 3D meibography, tear-meniscus evaluation, blink analysis, blepharitis documentation and ocular-redness classification.
The system captures single images, multishot sequences and video. Its camera produces 2592 × 1944-pixel JPEG photographs, while processed analytical images can be digitally upscaled to a published resolution of 23 megapixels.

Important Note
The OS1000 does not provide an autonomous diagnosis. All maps, measurements, images and software-generated suggestions must be interpreted by a qualified healthcare professional and should not be used as the sole basis for diagnosis or treatment.
Dry-eye examinations and automatic functions vary according to the Plus or Full software configuration. The computer, table and other accessories may be optional and must be confirmed in the quotation.
