LENSTAR - Central Corneal Thickness CCT

Central Corneal Thickness

Central Corneal Thickness (CCT) is measured using optical coherence technology, leading to unmatched accuracy and precision. Reproducibility of this measurement is as good as ± 2 microns, providing one of the base parameters for possible laser correction of the cataract surgery. Measuring CCT along with the other measurements takes less than 30 seconds, which will help increase patient flow.

How to Improve Anterior Chamber Depth (ACD) Measurement with LENSTAR

Anterior Chamber Depth

Just like other length measurements, ACD is assessed with optical coherence technology (OLCR). Combined with the CCT measurement, LENSTAR® provides you with the anatomical (= Aqueous Depth = AD) as well as ACD, as measured by ultrasound biometers. LENSTAR offers repeatable precision compared to slit lamp technology.

LENSTAR - How to Measure Lens Thickness Optically

Lens Thickness (LT)

Modern multivariable IOL calculation formulae use the patient's lens thickness as an input parameter. LENSTAR® provides the measurement of true lens thickness on the visual optical line of the patient using optical coherence technology (OLCR). No estimation or additional ultrasound measurement is required to get this important parameter. Lens thickness is one of the most important measurements of the Lenstar system.

LENSTAR - Axial Length Measurement - Faster, More Accurately

Axial Length (AL)

Optical coherence technology using a superluminescent diode as light source allows the measurement of the axial length of the patient’s eye on the visual optical line in highest precision and through dense cataracts. Axial Length is a major component in two important formulas used in the LENSTAR measurements.

Karatometry - Faster, Accurate Measurements with LENSTAR

Keratometry

A 32 marker pattern ensures precise assessment of the corneal curvature. The distribution of the marker on two concentric circles allows stable measurements even with non-compliant patients. The Keratometry measurement exemplifies the superiority of the LENSTAR system by providing expanded Keratometry information. LENSTAR uses 32 measurement points placed on two concentric rings of 16 points each at 1.65mm and 2.3mm.

How to Get Instant White to White Measurement for Ophthalmic - LENSTAR

White to White

For sulcus fixated IOLs and for the calculation of the IOL power using the Holladay II formula, LENSTAR® measures white to white distance (horizontal Iris width). The White to White measurement is gathered automatically form optical biometry. White to White is integral when implanting sulcus fixated ICLs. LENSTAR reduces "chair-time" by obtaining the white to white measurement instantly with the other measurements.

Instant Pupillometry Measurement Combined with 8 Other Measurements

Pupillometry

The software allows for measurement of the patient’s pupil diameter in ambient light condition. By measuring it instantly, LENSTAR saves you time. Pupillometry is an important addition to your data.


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.

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.

Retinal Thickness (RT)

An easy-to-use manual selection of the retinal peaks in the A-scan enables the user to measure RT (distance between the ILM and the RPE) and to calculate IOL based on the individual RT. A typical value for the RT is automatically displayed and employed for IOL calculation. LENSTAR delivers results comparable to existing ultrasound and optical biometers.

Special Eye Conditions

All of the measurements described here are available for measuring the “normal” cataract patient as well as for aphakic, pseudoaphakic and silicone oil filled eye conditions. In case of an error, you may even change the selected eye condition after completion of the procedure. The eccentricity of the visual optical line is assessed with respect to white-to-white as well as to the pupil center. Both are important parameters for laser refractive procedures.
