Features and Benefits
Chronos in Clinical Practice
Topcon Chronos is the all-in-one* digital refraction solution
Chronos combines binocular autorefraction, keratometry and subjective refraction in a single, compact device that can be placed anywhere in the practice. Now you can transform the time you spend on refraction into quality time with your patients.
*All–in–one system combines binocular autorefraction and keratometry with subjective binocular testing and visual acuity.
Practice Refraction Workflow
with SOLOS Automated Lens Analyzer + Chronos
+ CV-5000S Phoropter
1. Refractive data and previous spectacles loaded into Chronos before doctor enters exam room.
2. Chronos streamlines the refraction process to deliver time savings that may be used at the discretion of the doctor/practice.
3. Topcon SOLOS, Automatic Lens Analyzer
4. Topcon CV-5000S, Phoropter
