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 LS 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 Olsen1 formula, one of the latest generation multivariable IOL calculation methods, the Lenstar provides the user with the best...

Measured lens thickness – improved refractive outcomes4 With its integrated Olsen1 IOL calculation formula and the Lenstar’s unique measurement of the lens thickness, accurate prediction of the IOL position is provided for every type of eye. To improve refractive outcomes, the 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, as well as an on-board toric IOL calculator for sophisticated operation planning. For post-refractive cases – quick and reliable Shammas and...

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. HILL , MD, FACS MESA, ARIZONA, USA

Lens thickness matters Improve your refractive outcomes with measured lens thickness. Precise measurement of the entire eye − from cornea to retina − is key to achieving optimal IOL prediction accuracy in surgery. The Lenstar is the first optical coherence biometer to provide the surgeon with all the measurements necessary to take full advantage of the latest IOL prediction methods, such as the Holladay 2 and Olsen1 formulae, now integral to the Lenstar. Furthermore, it is ready to meet your requirements for future multi-variable formulae. Lenstar measurements include central corneal thickness,...

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 or Holladay 2 formula 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 captures axial dimensions...

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 T-Cone topography add-on and an optional toric surgery planning platform. 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 based on high-resolution...

Topography for torics – match the axis With the T-Cone optional topography add-on, 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. The T-Cone is combined with the toric surgery planner for optimal planning of the intervention. ACDPre LTPre Get the IOL position right – every time Estimating the postoperative IOL position is the key aim, but also the proverbial...

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 biometry acquisition is fast and easy; users report completion of five scans on both eyes in three minutes or less. 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,...
