Optical biometer LENSTAR LS 900 APS

Precision and Innovation: Enhancing Refractive Outcomes with the Haag-Streit LENSTAR LS 900 APS Optical Biometer

The Haag-Streit LENSTAR LS 900 APS optical biometer offers unparalleled precision in predicting intraocular lens (IOL) position for various eye types, thanks to its integrated Barrett Universal II and Olsen IOL calculation formulae. This advanced technology, coupled with the unique measurement of lens thickness provided by the Lenstar, ensures accurate outcomes for every patient. Moreover, to further enhance refractive outcomes, the Lenstar boasts dual zone keratometry or T-Cone topography, enabling precise measurement of astigmatism and axis.

The integrated Barret Toric Calculator within the Lenstar predicts toric IOL placement with exceptional accuracy, taking into account the posterior cornea. This comprehensive approach to refractive outcomes ensures optimal visual results for patients undergoing cataract surgery or lens replacement procedures. By accurately measuring lens thickness, the Lenstar contributes to improved refractive outcomes, maximizing patient satisfaction and visual acuity post-surgery.

Utilizing advanced technologies like the Radial Basis Function (RBF), the Lenstar analyzes multiple factors and non-linear relationships to predict IOL position accurately. By considering axial length, anterior chamber depth, and corneal curvature inputs, the RBF calculator identifies patterns that lead to precise IOL prediction. The inclusion of a boundary model ensures that results are provided only when the prediction is highly probable, adding an extra layer of reliability to the process.

In extensive testing conducted across multiple continents and involving thousands of cases, the Lenstar consistently demonstrated remarkable accuracy, with outcomes within ±0.50 D in 95% of cases. This level of precision remained consistent across various geographical locations and among different surgeons, highlighting the technologically advanced and reliable nature of the LENSTAR LS 900 optical biometer.

With the click of the acquisition button, the Haag-Streit LENSTAR LS 900 optical biometer can efficiently obtain seven different eye measurements, providing a comprehensive assessment of ocular parameters essential for precise surgical planning and IOL selection. These measurements include central corneal thickness (CCT), keratometry (K), topography (Topo), white-to-white distance (WTW), pupillometry (PD), lens thickness (LT), anterior chamber depth (ACD), and axial length. This multi-dimensional approach ensures that surgeons have access to detailed information about the patient's eye anatomy, facilitating personalized treatment plans and optimizing surgical outcomes.

The LENSTAR LS 900's unique dual-zone keratometer can be enhanced with an optional T-Cone topography add-on, offering true Placido topography of the central 6mm optical zone. This advanced capability enables the LENSTAR to provide high-resolution, accurate topographic data, essential for diagnosing corneal irregularities and planning customized surgical interventions. Additionally, the integration of the EyeSuite IOL Toric Planner in all new Lenstar Pro models further enhances surgical precision.

The EyeSuite IOL Toric Planner allows surgeons to meticulously plan toric surgeries based on high-resolution and true-color eye images captured by the LENSTAR. Whether used in combination with the T-Cone topography or based on the dual-zone keratometry of the standard unit, this platform enables precise determination of implantation axis, incision location, and user-defined guiding meridians directly on real patient images. By incorporating recognizable guiding lines to anatomical landmarks, surgeons can minimize residual astigmatism and optimize post-operative visual outcomes.

The detailed planning sketch generated by the toric planner can be easily printed and displayed near the surgical microscope, providing surgeons with clear guidance during the procedure. This integration of advanced imaging technology and surgical planning tools empowers surgeons to deliver personalized, high-quality care while minimizing the risk of post-operative complications, ultimately enhancing patient satisfaction and visual outcomes.
