Description
Haag-Streit Lenstar LS 900 Optical Biometer
The refurbished LENSTAR LS900 by Vision Equipment Inc. provides the user with a complete biometrical assessment of the patient’s eye in a single measurement procedure, including lens thickness, anterior chamber depth (lens position) and retinal thickness.
The all in one biometer, keratometer, pachymeter, pupillometer and IOL calculator.
Get up to nine measurements in one shot, including lens thickness.
T-Cone Toric Platform
LENSTAR’s unique measurement and planning platform for toric IOL now featuring the Barrett Toric Calculator for improved toric IOL prediction.
The Olsen Formula for superior IOL prediction LENSTAR is the first optical biometer on the market providing accurate measurement of the lens thickness, paired with the on board Olsen IOL calculation formula LENSTAR provides premium IOL prediction for all kind of human eyes.
Premium post refractive IOL calculation. Featuring the Shammas No-History, the Masket and the Modified Masket method, LENSTAR provides the cataract surgeon with an easy to use tool for the calculation of post refractive patients.
EyeSuite Biometry Software
In addition to the ease of using only a single measurement, the LENSTAR® also provides a user-friendly application and navigation of the software interface. This allows even inexperienced persons to easily begin to use the device without intensive training. Measurements can be performed by assistants, thus improving the efficiency of the clinic.
User-friendly and ergonomic
Best measurements for optimum IOL prediction
Ready for the future in IOL power calculation
Intuitive and open
Best measurements for optimum IOL prediction
LENSTAR® provides the user with a complete assessment of the human eye with the highest precision using OLCR technology. The patient fixates on the measurement beam, ensuring that all length measurements are taken on the visual optical line.
