Product overview

The SAB-500 is a standalone ophthalmic A/B scanner. It has three B-scan modes - normal, vitreous enhancement and retina observation - and is used to examine intraocular disease, showing where a lesion sits, how far it extends and how it relates to the surrounding tissue. Vitreous opacity, retinal detachment and intraorbital tumour are the usual findings. The A-scan measures anterior chamber depth, lens thickness and axial length, and the results are used to calculate intraocular lens power.

The whole system is built around a 15-inch colour LCD and a Windows operating system, so extra functions can be added later. A built-in battery gives about four hours of operation, which is enough to move between rooms without looking for a socket, and the unit measures 362 mm x 340 mm x 60 mm and weighs 2.5 kg.

The A-scan probe is a 10 MHz imported miniature probe that can be used handheld, in an immersion bath or mounted on a slit lamp, with contact and immersion scanning modes. Measurement modes cover phakic eyes, aphakic eyes and eyes with various intraocular lenses. Reports can be built from a custom template, and cases can be found again with multi-keyword search or with the preset expert dictionary.
