LENSTAR 900 Improving outcomes Tradition and Innovation – Since 1858, visionary thinking and a fascination with technology have guided us to develop innovative products of outstanding reliability: Anticipating trends to improve the quality of life.

LENSTAR Outstanding optic measurement results While the introduction of optical biometry revolutionized cataract surgery in the late 1990s, Haag-Streit is writing the latest chapter in biometry history with its Lenstar 900. 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 Hill-RBF, Olsen and Barrett formulas and the optional IOL Toric Planner considering the posterior cornea, the Lenstar provides...

Precise measuring data for the Hill-RBF Method Lenstar’s precise measurement technique in combination with the unique Hill-RBF Method allows accurate prediction of the IOL power for every type of eye. To improve refractive outcomes, Lenstar is the optimal choice. Perfect K values – best toric results The Lenstar features dual zone keratometry or T-Cone topography for precise astigmatism and axis measurement 2,3. The integrated Toric Calculator featuring Barrett12, Hill-RBF and Olsen predicts toric IOL, considering the posterior cornea for best refractive outcomes. For post-refractive cases –...

LENSTAR an excellent choice for toric and premium channel IOL The Lenstar is a remarkably easy to use all-in-one IOL power calculation tool that delivers exceptionally accurate axial length, anterior chamber depth and lens thickness by optical biometry. At the same time, its dual zone autokeratometry feature is precise and uniformly consistent. The Lenstar is an excellent choice for surgeons migrating towards torics and other premium channel IOLs where highly accurate outcomes are critical for success. « WARREN E.

Topography for torics – match the axis With the optional T-Cone toric platform, the axis and astigmatism measurement of Lenstar is extended with true 11-ring Placido topography. This additional data improves the efficacy and safety of toric IOL surgery, eliminating the risk of irregularities and allowing the user to double check the axis location on the topography maps as well as in the surgical planning sketch on high resolution images of the patient’s eye. The T-Cone is combined with the EyeSuite IOL Toric Planner for optimal planning of the intervention based on the Barrett Toric Calculator....

Complete optical biometry The all-in-one optical biometer and IOL planning platform Optical coherence biometry has revolutionized cataract surgery. Featuring OLCR technology, Lenstar is redefining optical coherence biometry. Cutting-edge, multivariable IOL calculation formulae, such as the Olsen, Barrett, Holladay 2 formula or Hill-RBF Method for sophisticated IOL calculation, demand more than just the axial length and keratometry measurement. Lenstar provides all the key biometric parameters simultaneously. In a single measurement scan and using optical low coherence reflectometry (OLCR), Lenstar...

Central corneal thickness As for every other Lenstar axial measurement, optical coherence biometry is used to measure CCT with stunning reproducibility of ±2 μm. 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 / Topography Lenstar’s unique dual zone keratometry, featuring 32 marker points, provides perfect spherical equivalent7, magnitude of astigmatism and axis position2,3, making it the biometer of choice for toric IOL's. With the optional...

Intuitive and efficient The ultimate platform for toric IOL planning Lenstar features a unique dual zone keratometer with a total of 32 marker points on two concentric rings of 1.65 and 2.3 mm in diameter for improved refractive outcomes with toric lenses2,3. It has now been complemented with an optional TCone topography add-on and the optional toric surgery planning platform EyeSuite IOL Toric Planner. The T-Cone enables the Lenstar to provide true Placido topography of the central 6  mm optical zone. The toric surgery planning platform allows planning and optimization of the surgical procedure...

HILL-RBF METHOD A new approach for IOL power selection The Hill-RBF Method is a purely data driven IOL calculation technique incorporating pattern recognition based in artificial intelligence and sophisticated data interpolation. It features a boundary model for improved accuracy and confidence. RBF stands for Radial Basis activation Function a method used in mathematical modeling. The Hill-RBF Method performs as good in short and long eyes15. Used on short eyes, it clearly outperforms Holladay16 and Hoffer Q16 and shows slightly better results than latest theoretical formula16. The elemental...

Connectivity is key Open data and intuitive user interfaces for optimal workflow The EyeSuite software is designed for optimal patient flow in busy practices. Paired with Lenstar’s one scan – get all measurements technology and the Automated Positioning System APS biometry acquisition is fast. Sophisticated capture and analysis algorithms − as well as the possibility to review the raw data of every parameter in detail to ensure correct measurement − result in full transparency and confidence that the biometry is accurate and precise. With EyeSuite software, Lenstar is fully networkable and allows...
