An excellent choice for all IOL types in any anatomy

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 Hill-RBF Method, Barrett and Olsen formula and the optional Toric Planner featuring the Barrett Toric Calculator, Lenstar provides the user with latest technology in IOL prediction for any patient.

Access to full eye data in a single click

In a single measurement scan using optical low coherence reflectometry (OLCR), Lenstar captures axial dimensions of all of the human eye’s optical structures. Lenstar also measures corneal curvature, white-to-white and more.

Complete optical biometry for better outcomes

Precise measurement of the entire eye − from cornea to retina − is key to achieving optimal IOL prediction accuracy in surgery.

Lenstar is the first optical biometer to provide the surgeon with all the measurements necessary to take full advantage of the latest IOL prediction methods, such as the Hill-RBF Method, Barrett and Olsen formulae, now integral to Lenstar.

Efficacy and precision

With APS, taking biometry measurements has never been easier. Biometry at a single click of the joystick saves time and increases patient and user comfort.

Reliable and easy to delegate – more efficient

Lenstar APS improves the repeatability of measurements, assisting the user in the fine alignment of the device and allows easy to delegate biometry for efficient patient flow in your practice.

The Automated Positioning System of Lenstar APS assists the user during the measurement process with dynamic eye tracking. This feature is combined with Lenstar’s superior measurement technology, providing axial measurements of the entire eye, dual-zone autokeratometry and optional topography for excellent IOL prediction in all eyes.

Perfect K values = best toric results

Lenstar features dual-zone keratometry or T-Cone topography for precise astigmatism and axis measurement. The integrated Barrett Toric Calculator predicts toric IOL, taking into account the posterior cornea for best refractive outcomes.

Improved outcomes with dual zone keratometry

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.

Topography for torics – match the axis

With the optional T-Cone toric platform, 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.

Improved refractive outcomes with any patient

EyeSuite IOL provides a comprehensive set of premium IOL calculation formulae for standard cataract patients as well as for patients with a history of keratorefractive surgery. The optional Toric Planner complements IOL planning with an intuitive tool for toric interventions.

Predictable outcomes

Modern multivariable formulae such as Barret and Olsen or the Hill-RBF Method integrated in EyeSuite IOL, provide predictable outcomes in any patient, independent of anatomic particularities. Using measurements of all compartments of the eye, these formulae allow for the prediction of the IOL positon and subsequently the IOL power with improved accuracy in short, normal and long eyes.

Hill-RBF Method 2.0 – exclusively

The Hill-RBF Method 2.0 is exclusivelly integrated in the Lenstar and is the first purely data driven IOL calculation technique incorporating pattern recognition based in artificial intelligence and sophisticated data interpolation. It features a unique reliability check providing confidence for every IOL calculation.

Master post refractive cases

EyeSuite IOL provides the user with a set of premium IOL calculation formulae for post-keratorefractive patients with or without known clinical history. Barrett True-K, Shammas No-History, and the Masket formulae have proven their efficacy in several peer-reviewed studies and may be regarded as best-in-class.

Match the axis

The Barrett Toric Calculator provides the user with one of the best toric IOL predictions available on the market. The toric calculator features dynamic calculation of the lens position for cylinder power transformation to the corneal plane as well as consideration of the anterior and the posterior corneal curvature for cylinder power and axis calculation.

EyeSuite IOL offers latest generation IOL calculations such as the Hill-RBF Method, Barrett and Olsen for standard IOL, enabling improved results with any patient. It further includes a comprehensive set of premium post-refractive formulae, including Barret’s True-K and the Masket formula which are regarded as best in class. For torics it optionally offers a complete planning suite to calculate the implant, considering the front and back of the cornea and create intuitive surgery sketches, enabling excellent transfer of the plan to surgery.

Artificial Intelligence with Hill-RBF

IOL data from all over the world collected by leading cataract surgeons is the foundation for the Hill-RBF. This big data is analyzed by pattern recognition based on artificial intelligence leading to highly accurate IOL predictions and providing confidence thanks to a unique reliability check.

Hill-RBF Method 2.0

The new version of RBF is based on a bigger dataset consisting over 3x the amount of data compared to the previous version. The data was complied by cataract surgeons from all over the world thus it encompasses a huge range of human anatomy and IOL powers leading to highly accurate IOL predictions. In addition the Hill-RBF was complemented with the well-established Abulafia-Koch algorithm for torical applications.

Stay on target any time

Standard IOL calculations provide good results in average eyes; they fail in short and long eyes as well as eyes with special anatomic features. EyeSuite IOL features the Barrett and Olsen formula, enabling excellent refractive results with any patient anatomy.

Lens thickness – improved results

Standard formulae use axial length and K measurements to calculate IOL power, limiting their performance with unusual eyes. Barrett and Olsen use more parameters, including anterior chamber depth and lens thickness to estimate implant power. This improves the prediction of the implant position and enables better results, independent of the patient anatomy.

Barrett Universal II – a formula for all seasons

Unlike most standard formulae, the Universal II formula is a thick lens formula, taking into account the changes in optics design of IOLs at different powers. In addition to AL and Ks, it uses ACD, lens thickness and WtW measurement to predict the lens position and IOL power, leading to excellent refractive outcomes in all patients.

Olsen – the C-constant a new concept

The Olsen formula uses ray tracing, a method well known from optics design, to calculate lens power and the concept of the C-constant to predict implant location. As an input parameter, apart from AL and Ks, Olsen uses ACD and LT measurement enabling excellent implant position prediction in all eyes.

The right tools for post refractive patients

IOL calculation in post refractive patients is one of the most demanding tasks in cataract surgery. To support the surgeon with this challenge, EyeSuite IOL features a comprehensive set of cutting-edge formulas for post refractive patients with or without clinical history.

Best in class formulae for premium results

IOL power calculation in patients with prior RK, LASIK or PRK, presenting with no history, is easily achieved with the integrated Barrett True-K and Shammas No-History method. If the change in refraction caused by the refractive procedure is known, then the Barrett True-K with history, Masket and modified Masket formulae may also be used.

Match axis and cylinder

Getting the cylinder value and axis location right is key with toric IOL. The optional EyeSuite IOL Toric Planner features the Barrett Toric Calculator for excellent IOL prediction and an intuitive graphical planning interface to create sketches to transfer the plan to surgery.

Excellent calculation, intuitive planning

The EyeSuite IOL Toric Planner provides the user with an intuitive tool to plan the toric intervention on high resolution eye images. Using the incision optimization tool enables the surgeon to put his incision in the exact right location to achieve the minimum anticipated residual astigmatism, with the lowest toric power IOL implanted.
