Haag-Streit Lenstar LS900 Optical Biometer

• Dramatically speeds your workflow and increases patient satisfaction - Get up to eight measurements in one shot, including lens thickness. This all-in-one Biometer, Keratometer, Pachymeter, Pupillometer and IOL estimator
• Ultimate in simplicity - All measurements use laser optical technology, so you just align once and get all results
• Highly reproducible results on all parameters since you are measuring on the true optical axis.

Lenstar LS900®is an optical biometer that is capable of making highly accurate measurements along the visual axis, over the curvature of the cornea and in addition other parameters that can be used to provide accurate estimations of patient’s IOLs.

Lenstar LS900® is the next generation of biometer. It uses OLCR technology to provide true A-Scan measurements without contacting the eye. OLCR makes it possible to measure more parameters than with other optical biometers and therefore provide additional data that is required for current cataract and refractive surgery.

More accurate than other biometers - Lenstar LS 900 has been proven to be comparable to existing products that produce axial length measurements. The correlation is very close and the data was presented recently at ESCRS in Berlin. Intra user variability is also very low as the unique alignment system on Lenstar LS900® ensures that measurements are only made when the patient fixates correctly.

The average patient can have both eyes tested within 3 or 4 minutes. The A and K data are captured simultaneously and all the patient needs to do is fixate. The Lenstar LS 900® makes 16 measurements of A and K data each time the trigger button is pressed and the mean data is presented. K data is taken three times within the 16 A-scan measurements. Providing the patient retains relatively good position and fixation, it is suggested that 5 of these measurements are obtained. The software will provide the mean data along with the standard deviation at each measured point.
