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.

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.
