Lenstar LS 900

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 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 Barrett and Olsen formulae,
now integral to Lenstar.

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, 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.
