Features and Benefits
Delegate Data Collection
SightPilot software guides the operator through the entire process, so you can delegate the upfront refraction and acuity testing to a technician.
Maximize Doctor-Patient Time
Enter the exam room with all refraction data at your fingertips to make the most of your time with each patient.
Save Space
Chronos combines an autorefractometer, a keratometer, phoropter and acuity testing chart into a single instrument with a compact footprint that can be placed anywhere in the practice.
Grow Your Practice
Use the time saved to see more patients, add a new specialty to the practice or spend more time counseling patients about their eye health.
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
