Advanced Biometry1,2,7,8

 

The swept-source OCT ARGOS® Biometer with Image Guidance by Alcon® is an innovative solution, designed to enhance your surgical experience and help to achieve better patient outcomes.1,2,7,8

The ARGOS® Biometer is faster than other market-leading biometers.1-5† With a biometric data capture time of less than 1 second and a higher scanning speed, 50% faster than IOLMaster* 700, the ARGOS® Biometer allows for enhanced efficiency and accuracy of eye measurements.1,9

Auto-capture mode automatically records measurements when the patient is optimally aligned, without requiring any extra steps.

 

The ARGOS® Biometer captures biometric data of5,10:

  • Anterior Chamber Depth (ACD)
  • Keratometry (K)
  • Corneal Diameter / WTW
  • Central Corneal Thickness (CCT)
  • Axial Length (AL)
  • Aqueous Depth (AD)
  • Pupil Size (PD)
  • Lens Thickness (LT)
  • Angle Kappa Coordinates (Px and Py)

The ARGOS® Biometer Provides Higher Acquisition Rates Than Other Market-Leading Biometers1,2,7,8

With SS-OCT Technology and proprietary Enhanced Retina Visualization mode, the ARGOS® Biometer provides unsurpassed dense cataract penetration and accuracy of axial length acquisition.1,2,7,8


It allows for confidence in refractive outcomes even in the case of grade 4+ cataract patients.12

A comparison of biometry images captured by the ARGOS Biometer in normal mode and in enhanced retina visualization (ERV) mode. ERV mode reconfigures the internal optics to enhance the signal at the retina by 10 times compared to normal mode.

The ARGOS® Biometer shows significantly higher acquisition rates in grade 4+ cataracts compared to the IOLMaster* 700 and other market-leading biometers, while significantly reducing the need for time-consuming ultrasound biometry.1,2

A bar graph comparing the axial length acquisition rate of 3 SS-OCT biometers in patients with dense cataracts. The ARGOS Biometer had an acquisition rate of 89.9%, Zeiss IOLMaster 700 had an acquisition rate of 63.6% and Tomey OA-2000 had an acquisition rate of 80.8%. The study population was 99 eyes with grade 4+ cataracts. A bar graph comparing axial length acquisition rate of three biometers in random cataract patients. The ARGOS Biometer acquisition rate was 96% with 4% of patients requiring ultrasound A-scan. The Lenstar biometer acquisition rate was 79% with 21% of patients requiring ultrasound A-scan. The Zeiss IOLMaster 500 Biometer acquisition rate was 77% with 23% of patients requiring ultrasound A-scan. The study population was 56 eyes with advanced cataracts.

A table comparing the refractive outcomes in patients with nuclear cataracts between the ARGOS Biometer and IOLMaster 700. In low density eyes, the mean absolute error was not statistically different between the ARGOS Biometer and IOLMaster 700. In medium and high density eyes, mean absolute error was significantly lower with the ARGOS Biometer compared to IOLMaster 700.

    SS-OCT Enhanced Keratometry


    The ARGOS® Biometer’s SS-OCT-enhanced keratometry helps with the acquisition of accurate measurements


    The ARGOS® Biometer utilises SS-OCT-enhanced keratometry with angle-to-angle, cornea-to-retina, real-time OCT guidance, allowing the user to monitor patient alignment and fixation and helping acquisition of accurate measurements every time.2,13

    The ARGOS® Biometer keratometry measurements show high correlation with IOLMaster* 500, IOLMaster* 700 and LENSTAR*.2,13.

     

    Segmented Axial Length


    “The ARGOS® [Biometer] uses segmented method to measure the eye - it measures each segment of the eye in its precise velocity. That makes a difference especially in very long and very short eyes.” - H. John Shammas, MD, Medical Director, Shammas Eye Medical Centre

    An illustration of an eye showing how the ARGOS Biometer uses the swept-source laser to detect reflections of each interface of the eye to calculate the total axial length. A table comparing the refractive error in eyes measured with the ARGOS Biometer compared to eyes whose axial length was calculated using the simulated CRI method. A higher percentage of eyes measured with the ARGOS Biometer were within 0.50D of target refraction.
