The future begins now – the all in one optical biometer
LENSTAR LS900® provides the user with a complete biometrical assessment of the patient’s eye in a single measurement procedure, including lens thickness, anterior chamber depth (lens position) and retinal thickness.

The all in one biometer, keratometer, pachymeter, pupillometer and IOL calculator
Get up to nine measurements in one shot, including lens thickness. Lenstar provides highly accurate laser optic measurements for every section of the eye − from the cornea to the retina. With its integrated Hill-RBF Method, Olsen formula and the optional Toric Planner featuring the Barrett Toric Calculator, Lenstar supplies the user with latest technology in IOL prediction for any patient.

T-Cone Toric Platform
LENSTAR’s unique measurement and planning platform for toric IOL.

The Olsen Formula for superior IOL prediction
LENSTAR is the first optical biometer on the market providing accurate measurement of the lens thickness, paired with the on board Olsen IOL calculation formula LENSTAR provides premium IOL prediction for all kind of human eyes.

Premium post refractive IOL calculation
Featuring the Shammas No-History, the Masket and the Modified Masket method, LENSTAR provides the cataract surgeon with an easy to use tool for the calculation of post refractive patients.



With the Eyestar 900, Haag-Streit is opening a new chapter in measuring, imaging and diagnosing the human eye with the introduction of a complete swept-source OCT-based eye analyser. The Eyestar 900 features swept-source technology, enabling precise measurement, as well as topographic assessment of the front and back corneal surface and the anterior chamber, including the lens, as well as imaging of all these structures. It also includes cornea-to-retina biometry of the entire eye.

Imaging of the entire anterior chamber, including the crystalline lens, allows the user to easily verify any measurement and to identify anatomical anomalies that may interfere with planned surgical procedures. Topographic maps of the anterior and posterior cornea and pachymetry maps enable users to improve their surgical plan and review patients’ suitability for specific interventions, such as toric- or multifocal IOL.
