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.
Thirty-two points of difference
LENSTAR provides you with a complete biometrical assessment of the patient’s eye—seven measurements—in a single procedure, including:
Pachymetry, Lens Thickness, Keratometry, Pupillometry, Axial Length, ACD, White to White
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.
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.
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.
