Real-time Data.

Only the HOLOS IntraOp Wavefront Aberrometer continously streams patient refractive data, providing you with a nonstop look at your procedure as it changes.

HOLOS Barrett IOL Formula™ : Real-time IOL Prediction

Thanks to the exclusive HOLOS Barrett IOL Formula — developed in collaboration with Graham Barrett, MD, Warren Hill, MD, and Douglas Koch, MD — only HOLOS delivers:

  • Increased accuracy and precision, using aphakic data and best-in-class Barrett formulae optimized for the HOLOS system
  • Real-time IOL power calculation and prediction during cataract surgery
  • A net refractive solution for the eye, including anterior and posterior corneal curvature

HOLOS InSightTM

Our cloud-based physician portal seamlessly integrates your patient's pre-operative biometric information with HOLOS intraoperative data, helping you optimize planning*, track outcomes*, and refine surgeon factors over time*.


*Planned feature release in 2017.

The HOLOS Barrett IOL Formula leverages the power of the HOLOS InSight portal to deliver the advantages of two leading-edge technologies-working together, and working for you.

  • Before surgery, preoperative biometric information is entered into HOLOS InSight and populates the HOLOS interface
  • During surgery, HOLOS Wavefront Technology provides real-time refractive data and the exclusive the HOLOS Barrett IOL Formula calculates lens diopter recommendations
  • Post procedure, HOLOS procedural and lens power data may be uploaded to HOLOS InSight for record-keeping and analysis*
*Planned feature release in 2017.
