While the introduction of optical biometry revolutionized cataract surgery in the late 1990s, Haag-Streit has introduced the latest technology in biometry with the release of the Lenstar LS 900.

The 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, one of the latest generation multivariable IOL calculation methods, the Lenstar provides the user with the best possible IOL prediction.

Dual zone keratometry, with 32 measurement locations or topography measurement with the optional T-Cone, provides reliable and precise measurements for the K values, axis, and astigmatism which are essential to the sophisticated planning of toric lenses. The Lenstar LS 900 offers the optimal planning platform for superior refractive outcomes in cataract surgery, both now and in the future.

Lenstar LS 900 Features & Benefits:

• Improves Refractive Outcome by eliminating the risk and liability of transcription errors.
• Improves Patient Flow by eliminating the need for separate ultrasound measurements for Lens Thickness and Pachymetry, Separate Keratometry and Pupillometry – currently measured separately.
• Improves Data Flow using a separate, external PC, for direct communication with EMR and Networks.
• Improves Measurement Precision with OLCR (Optical Low Coherence Reflectometry).
• Improves Consistency in Measurements by detection of loss of fixation.
• LENSTAR is the first optical biometer which uses the precision of OLCR (Optical Low-Coherence Reflectometry) for all its measurements, including ACD and lens thickness. OLCR is an advanced technology, similar to Time Domain OCT.
• As a biometer of the entire eye, one LENSTAR scan consists of 16 individual full eye scans and 4 individual keratometric scans, taken on 2 concentric rings, along the patient’s visual axis.
• The LENSTAR software runs on an external PC. This minimizes costly upgrades, software crashes and hardware repairs, and allows direct communication with EMR and networks as well as auto-population of data fields from third party IOL calculators such as Holladay II, eliminating the risk and liability potential of transcription error.
• All of the standard IOL prediction formulas (Holladay I, SRK-T, Haigis and Hoffer Q) are built into the LENSTAR software – with potential for future formulas to be added. Since LENSTAR measures more parameters than current formulas allow, the system is ready to incorporate future generations of power calculations as they are developed.
• LENSTAR uses a proprietary intelligent detection system. The patient fixates on the measurement beam. This ensures all measurements are on the patient’s visual axis. If the patient blinks or loses fixation, LENSTAR detects this and resumes again when the patient’s fixation returns.
