Informations produit documentées
Lenstar LS 900 is Haag-Streit’s non-contact optical biometer using optical low-coherence reflectometry (OLCR). It brings together measurements used for intraocular-lens calculation: axial length, cornea, anterior chamber, crystalline lens and complementary parameters. Results are processed in EyeSuite IOL. Cornea map features, software modules and T-Cone topography must be identified according to the version and options of the ASEM configuration; they are not presented as universally included standard equipment.
Biometry: axial length and anterior segment
Axial length: 14–32 mm
Anterior chamber depth: 1.5–6.5 mm
Lens thickness: 0.5–6.5 mm
Display resolution: 0.01 mm
The instructions report in-vivo repeatability at one standard deviation (1σ): ±0.035 mm for axial length, ±0.04 mm for anterior chamber depth and ±0.08 mm for lens thickness. These results come from the manufacturer study, not a guarantee of accuracy for every eye. The measurement ranges in the instructions are based on Phakic measurement mode.
Cornea and complementary measurements
Central corneal thickness: 300–800 µm
Corneal display resolution: 1 µm
Corneal curvature radius: 5–10.5 mm
Keratometric axis: 0–180°
White-to-white distance: 7–16 mm
Pupil diameter: 2–13 mm
Dual-zone keratometry uses 32 points. The current brochure distinguishes a calculated axial Cornea map over the central 3 mm using 48 points from optional 11-ring Placido T-Cone topography over 6 mm. These representations are not interchangeable; available software versions and options must be confirmed.
Using measurements in EyeSuite IOL
EyeSuite IOL brings together documented measurements and IOL calculations, including Hill-RBF, Barrett Universal II and Haigis. Listed interfaces include DICOM SCU, GDT and EyeSuite scripting/command-line interfaces. Modules, formulas and connections depend on the software configuration and installation. The monitor in the official media illustrates an installation and does not prove that it is supplied with the biometer.
Installation and configuration: identifying the variant
Width: 310 mm
Depth: 260 mm
Height: 420 mm
Primary power supply: 100–240 V AC
Frequency: 50–60 Hz
Standard Lenstar weighs 6.2 kg; Lenstar APS weighs 6.6 kg. Standard secondary supply is 12 V / 1 A, whereas APS supply is 18 V / 1.7 A. These configurations must not be combined. The specified medical power supply, computer, software and ASEM installation options must be identified in the quotation.
