Haag-Streit Lenstar 900 uses optical low coherence reflectometry (OLCR) for measurement of the axial length parameters of the eye. This is the basis for excellent IOL prediction. It was the first optical biometer to capture all relevant axial dimensions of the eye to take full advantage of latest generation IOL prediction methods. Additionally, the Lenstar 900 measures a wide range of useful biometric parameters, including pupillometry, corneal curvature, white-to-white, and more.

The Lenstar 900’s dual-zone keratometry ensures highly precise measurements of the K readings, axis orientation, and astigmatism. Enhancing its capabilities, the "cornea map" feature generates a detailed axial curvature map of the central anterior cornea, utilizing data from 48 measurement points. With the optional T-Cone add-on, the Lenstar 900 expands further to provide true 11-ring Placido topography of the central 6mm optical zone. These features facilitate the detection of irregular astigmatism and offer precise verification of axis alignment, ensuring optimal IOL selection and refractive outcomes.

Scientific credibility is built over time, and the Lenstar 900 stands as a testament to precision and reliability in biometry. Validated in numerous studies and cited in 3,292* scientific articles by the end of 2024 – including 389* in 2024 alone – it remains a cornerstone for researchers and clinicians worldwide. With thousands of devices sold, millions of patients have benefited from excellent refractive outcomes.

Fast measurement times and effective delegation are key to running an efficient cataract clinic. The Lenstar 900’s biometry, keratometry, pupillometry, and white-to-white measurements, are all acquired during one single data acquisition process. Thanks to its intuitive user-interface and its Automated Positioning System APS, the Lenstar 900 is a productive and cost-effective biometer.

With myopia becoming a global pandemic, Haag-Streit has introduced Lenstar Myopia, utilizing the core technology and accuracy of a Lenstar 900 biometer to address the challenge. The tailored myopia control software—with tools for detection and follow up of myopia and parent education reports—is available to any Lenstar 900 and Eyestar 900 user with a straight-forward software update.
