ALCON WaveLight Allegro Topolyzer Vario Topographer w Windows Laptop & Table

The ALLEGRO Oculyzer performs topography measurements of the front and back surfaces of the cornea and corneal volume.

Advanced topography measurements enable pre-operative planning for any corneal refractive treatment and allow progression control after corneal surgery. In addition the ALLEGRO Oculyzer features an improved IOL calculation software for post-LASIK patients.

No matter what data you need, WaveLight technology offers a broad range of advanced diagnostic tools to meet the requirements of both your therapeutic procedures and your patients.

Easy alignment and capture of data ensures accurate readings.Wavefront data is gathered out to a 9.5mm area allowing calculation of mesopic refractions in addition to extremely accurate day refractions. Blue light, 33 ring, placido disc topography is easier for patients to tolerate and is gathered in one second.



Laser Locators sells used and refurbished wavefront aberrometers for creating wavefront maps for patients that have cornea or lens imperfections. We offer the aberrometers that were designed to work specifically with the excimer platform and offer a complete custom experience for the patient. The most popular excimers that use an aberrometer are the AMO Visx S4, Wavelight Allegretto and the Nidek EC5000. We carry a variety wavefront aberrometers including the AMO/VISX Wavescan, Nidek Marco OPD and the Alcon Wavelight Allegro.

AMO Visx Wavescan Wavefront Aberrometer

The AMO WaveScan WaveFront™ System leads the industry for outstanding wavefront achievement and analytic capabilities. Using AMO Fourier algorithms, WaveScan captures the unique imperfections of each patient’s eye using 100 percent of the available Hartmann-Shack data points for more accurate wavefront error reconstruction. Fast and powerful, the WaveScan System delivers unprecedented measurement accuracy by enhancing the precision of the Advanced CustomVue™ procedure.

The system provides the highest resolution available for any shape pupil (up to 7 mm); enabling precise, individualized treatment for the broadest range of visual imperfections.

Additional Benefits include:

  • Personalizes the Advanced CustomVue™ treatment for each patient according to the unique characteristics of his/her eyes.
  • Allows you to link diagnostic information to laser treatment.
  • Advanced features like off-line programming and auto exam selection improves workflow efficiency.

Alcon Wavelight Allegro Custom Analyzer

The WaveLight ALLEGRO Analyzer® Device is an ideal diagnostic device to support the decision-making process for customized laser vision correction. It measures the complete optics of the eye and calculates the individual wavefront aberrations.

This unit will sync flawlessly with your Alcon laser!  It measures the complete optics of the eye and calculates the individual wavefront aberrations. Therefore it greatly enhances the range of possible treatments, from a Wavefront Optimized® procedure to sophisticated wavefront-guided treatments. The rotating panel PC includes both a computer and monitor which can be used for showing patients their individual data. Additionally, it is compact and provides an integrated USB port which is easily accessible and useful for data backup.
