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 provides highly precise, gold standard measurement of keratometry, astigmatism, and axis orientation. The optional T-cone further extends Lenstar 900 to offer true 11-ring Placido topography of the central 6mm optical zone. This supports identification of irregular astigmatism and allows double checking on the axis location, both enabling well-informed IOL selection and increased safety of toric IOL surgery.

Since its introduction in 2008, the Lenstar 900’s prediction accuracy and excellent outcomes have been proven in more than 150 studies. With thousands of devices being sold, millions of patients have enjoyed superb outcomes & fewer surprises when Lenstar 900 was part of their cataract planning process.

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.
