Description

Lenstar LS900 is an optical biometer that accurately captures all dimensions of the human eye. It is used mainly in the case of IOL (Intraocular Lens) surgery, where the eye’s natural lens needs to be replaced by an artificial one. 

In such cases, having the correct dimensions of someone’s eye structures is essential. Proceeding with the surgery without taking accurate or imprecise measurements can be very risky.

Lenstar LS was developed by the Haag-Streit Group, whose headquarters are in Switzerland. The company is a leading provider of medical equipment, and one of the fields they cater to is the optical healthcare industry. 

Optical Biometry Devices are an increasingly trusted method to assess the anatomical features of the human eye. Precision is critical when measuring eye characteristics; otherwise, it can lead to risky issues. A primary medical equipment industry caters to the optical care sector. 

Equipment used in Optical Biometry should always be bought from a trusted source and tested before subjecting a patient to it. Equipment in the market is constantly evolving. No matter how accurate the equipment is, medical assessments always have room for more precision. 

 

Lenstar LS900 Key Features:

  • With its integrated Hill-RBF method, Barrett and Olsen formula, and the optional Toric Planner with the Barrett Toric Calculator, the Haag-Streit Lenstar provides the user with the latest technology in IOL prediction for every patient.
  • In a single measurement scan using optical low coherence reflectometry (OLCR), the Haag-Streit Lenstar captures axial dimensions of all-optical structures of the human eye.
  • Dual-zone keratometer; equivalent to gold-standard manual keratometer (Javal).
  • Sixteen measurements are taken per meeting. In normal mode, 94.4% of the eyes can be measured; in Dense Cataract Mode, 98.4%.
  • User-friendly, both manual and automatic models are available.
  • T-cones Toric planner as an option for toric lenses.

The future begins now – The “all in one” biometer.

The Haag-Streit Lenstar LS enables a complete biometric measurement of the patient’s eye in a single step, including lens thickness (lens position), anterior chamber depth, and retinal thickness. The LENSTAR is now the gold standard for distance measurement.

  • “All in one” means all measurement results with one measurement
    Nine results with one measurement, including lens thickness
  • T-Cone Toric Platform
    LENSTAR’s unique measurement and planning platform for toric IOLs. Now featuring the Barrett Toric Toric IOL Calculator for improved prediction.
  • Implemented Olsen Formula for Excellent IOL Prediction
    The LENSTAR was the first optical biometer on the market to measure lens thickness (LT). With this option and the Olsen formula integrated with the LENSTAR, you get the best predictive values ​​for premium IOLs.
  • Perfect post-refractive IOL calculation
    After Lasik, the integrated post-Lasik formulas Shamma No-History, Masket, and modified Masket enable a quick and easy calculation.

More Features:

Lenstar LS is an excellent choice regarding optical anatomy measurements. It is one of the best technology in the market that caters to optical procedures. This optical biometer is also the first to assess crystalline eye lens thickness. 

Regarding errors and inaccuracies in optical diagnosis, incorrect measurements can lead to vision issues. To combat that, optical surgeons are always looking for the latest technologies on the market that can predict accurate measurements and are easy to use. 

Here are a few other features of this optical biometer that make it desirable in the optical care industry:

Complete eye data

Through a single scan, the LS900 gathers all axial dimensions of the eye, from lens thickness to corneal curvature. It also captures other data required in various optical procedures or calculations.

A plus point of this device is that it is non-invasive and contactless. Surgeons always look to reduce the amount of physical contact during an examination. Lenstar LS 900 takes care of that issue as well.

IOL Surgery

Intraocular Lens surgery is performed when a person cannot form clear vision in their eye; the condition is called a cataract. It alters the vision of an individual, and things start appearing blurry.

Cataracts arise when a person grows old or suffers some injury. Sometimes genetic disorders are also responsible for this condition.

To correct this state and restore the quality of vision, IOL surgery is performed. For this surgery to be successful, accurate dimensions of a person’s natural eye lens are required.

LS 900 provides the most accurate assessments regarding IOL power.

Optical Biometry for better outcomes

In straightforward terms, optical Biometry refers to optical measurements. Optical Biometry is required to measure the power of the eye’s cornea, which is used to calculate the Intraocular Lens power.

The thickness of the eye lens is a determining factor in the image produced by the eye. When the eye lens gets cloudy, people cannot see what they are looking at.

This condition is known as a cataract. Ophthalmologists suggest Intraocular Lens surgery in case of cataracts.

Best Results with the excellent K value:

In optical Biometry, ‘K-values’ refer to measurements of the eye’s corneal surface’s flat meridian and steep meridian. 

LS 900 has T-Cone topography for precise axis measurement. It comes in handy with patients suffering from Astigmatism. 

Dual-Zone Keratometry 

Keratometry refers to the assessment of the corneal radius of curvature. Corneal curvature determines the power of the cornea. 

Lenstar LS provides dual-zone Keratometry, measuring both axis length and Astigmatism. This dual-zone keratometry feature is equal to the “Gold Standard” manual Keratometry manufacturers recommend for IOL. 

Both T-Cone topography and Keratometry are used in patients with Astigmatism.

Improved Refractive Outputs

A set of premium IOL calculation formulas are provided by EyeSuite IOL software. These formulas help in patients with a history of keratorefractive surgery and regular cataract patients. 

Lenstar LS 900 also comprises a ‘Toric Planner’ (optional) that assists patients’ IOL selection and planning process.

Multiple measurements per procedure

LS 900 gathers seven different types of measurements through a single scan. Some of them are:

  • Lens Thickness
  • Pupillometry
  • Axial Length
  • White to White
  • Keratometry
  • Anterior Chamber Depth
  • Pachymetry

Advanced IOL Planning

Lenstar LS 900 provides the user with the best toric IOL predictions with the help of the Barrett Toric calculator.

This calculator gives a dynamic calculation of the lens position in the eye. This leads to better cylinder power and better axis calculation. In many cases, all these parameters may not be required, but they are essential data in the case of refractive procedures.

Besides the above seven measurements, Lenstar LS 900 can also assess other areas of the eye structure and provide accurate results.

Useful for Special Eye Conditions: 

Apart from the above measurements, Lenstar can also be used on pseudophakic and aphakic patients.

The software also has provisions in case of manual errors. If the selected eye condition is incorrect, the surgeon can easily change it after the procedure.

Other advantages:

In addition to accurate optical assessments and ease of use, there are other advantages to this optical biometer.

LS 900 software is the latest technology and is very easy for all patients. Compared with competitors whose software remains outdated even after upgrading, this device is easier to operate.
