Haag Streit Lenstar 900
Complete Optical Biometry - The all-in-one optical biometer and IOL planning platform
With its intergrated Olsen 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.
The Lenstar features dual zone keratometry or T-Cone topography for precise astigmatism and axis measurement. The intergrated Barret Toric Calculator predicts toric IOL, considering the posterior cornea for best refractive outcomes.
Shammas and Masket IOL calculation methodologies can be used for post-refractive patients even without any clinical history available.

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 Olsen formulae, now integral to the Lenstar. Furthermore, it is ready to meet your requirements for future multi-variable formulae. With the optional EyeSuite Toric Planner featuring the Barrett Toric Calculator, the Lenstar enables intuitive and accurate planning of astigmatic cases. Operation sketches based on high resolution images of the patient’s eye complete this sophisticated planning tool. Lenstar measurements include central corneal thickness, anterior chamber depth, lens thickness, axial length, keratometry, white-to-white distance and pupil diameter.
Precise measurements and intuitive planning - best toric results
Lenstar’s unique dual zone keratometry provides measurement of the axis and astigmatism, equivalent to the “Gold Standard” manual keratometry recommended for toric IOL by manufacturers. The closely spaced 32 measurement point pattern improves precision, both delivering more data and minimizing the need for software data interpolation. Optionally, the Lenstar can be equipped with the T-Cone topography add-on. That feature not only enables axis and astigmatism measurement but also offers full topography maps of the central 6mm optical zone. In addition to topography, EyeSuite IOL also now features a toric IOL planning platform that is included with the T-Cone.
Fast, precise and comprehensive for better refractive results
The measurement process of the Lenstar is fast and optimized to ensure maximum patient comfort – users report five scans of both eyes in three minutes or less, optional the Automated Positioning System (APS) features dynamic eye-tracking allowing easy automated measurement acquisition with a single click. The Dens Cataract Measurement (DCM) Mode ensures state-of-the-art cataract penetration. Each of the measurements can be validated for efficacy and adjusted, if necessary, to ensure complete biometry accuracy. In addition to the Olsen, Barrett and standard IOL calculation formulae Eye Suite IOL provides the user with a set of premium IOL calculation formulae for post-keratorefractive patients. The Shammas No-History and Masket formulae have both proven their efficacy in several peer-reviewed studies and may be regarded as best-in-class.
