MSRP:
The Lenstar provides highly accurate laser optic measurements for every section of the eye − from the cornea to the retina − and is the first optical biometer on the market that can measure the thickness of the crystalline lens. With its integrated Olsen formula and the optional Toric Planner featuring the Barrett Toric Calculator, the Lenstar provides the user with latest technology in IOL prediction for any patient.
Dual zone keratometry, with 32 measurement locations or topography measurement with the optional T-Cone, provides reliable and precise measurements for the K values, axis, and astigmatism that are essential to the sophisticated planning of toric lenses. The Lenstar LS 900 offers the optimal planning platform for superior refractive outcomes in cataract surgery, both now and in the future. See the brochure for more information and sources.
Pre-owned (used) instruments include warranty covering parts, labor, and shipping. All certified pre-owned inventory from Lombart is completely refurbished, tested, and re-calibrated by factory-trained technicians. Please allow up to 4 weeks for delivery.

FEATURES:
Central corneal thickness (CCT)
As for every other Lenstar axial measurement, optical coherence biometry is used to measure CCT with stunning reproducibility of ±2μm. CCT is a key parameter in glaucoma diagnosis, and is also used for laser refractive surgery and/or to differentiate prior myopic or hyperopic LASIK procedures when there is no patient history.
Keratometry (K)/Topography (Topo)
Lenstar’s unique dual zone keratometry, featuring 32 marker points, provides perfect spherical equivalent , magnitude of astigmatism and axis position, making it the biometer of choice for toric IOL’s. With the optional T-Cone topography add-on, Lenstar provides full topography maps of the central 6mm optical zone that are crucial for cataract planning.
White-to-white (WTW)
Based on high-resolution color photography of the eye, every white-to-white measurement can be reviewed and adjusted by the user if necessary. As such, it is fully reliable for use with anterior chamber and sulcus-fixated phakic IOLs. It can also be used to determine advanced IOL calculation formulae.
Pupillometry (PD)
Measurement of the pupil diameter in ambient light conditions can be used as an indicator for the patient’s suitability for apodized premium IOLs, as well as for laser refractive procedures.
Lens thickness (LT)
Accurate measurement of the lens thickness is key to optimal IOL prediction accuracy when using the latest IOL calculation formulae, Olsen or Holladay 2. Measuring the lens thickness with Lenstar significantly improves the IOL prediction accuracy of Holladay 2 and leads to a different IOL power selection in 30% of cases.
Anterior chamber depth (ACD)
Like all axial dimensions captured by the Lenstar, ACD is measured by optical coherence biometry, providing more precision and reproducibility. This allows ACD to be measured on phakic as well as on pseudophakic eyes. Additionally, the Lenstar is able to display the anatomical anterior chamber depth (endothelium to anterior lens surface).
Axial length (AL)
OLCR technology, using a superluminescent diode as the laser source, enables measurement of the axial length of the patient’s eye, precisely on the patient’s visual axis and in the presence of dense media. The user can review and move all of the measuring gate positions on the A-scan if necessary. The Lenstar A-scan appears very similar to an immersion ultrasound scan, for easy user interpretation. The advanced digital signal processing used with the Dens Cataract Measurement (DCM) mode provides cutting-edge performance with respect to penetration rates.
Special eye conditions
All of the described measurements are available for use on the regular eye, as well as for aphakic, pseudoaphakic and silicone oil-filled eyes. In case of error, users may even change the selected eye condition after completion of the measurement procedure.
