Automated Binocular Refraction System
Increase patient convenience, optimize workflow and grow your practice – without compromise.
Chronos combines binocular autorefraction and keratometry measurements with binocular subjective testing and visual acuity in a single instrument that occupies a minimal amount of space and optimizes workflow.
Introducing SightPilot™
SightPilot™ is optimized for understanding and efficient workflow, facilitating delegation when required.
• SightPilot™ simplifies the user interface to provide a step-by-step guide through the refraction process.
• At each step, the operator is given instructions to proceed with the refraction, based on the patient’s response.
Delegate
SightPilot™ is a guided refraction system that simplifies the exam and facilitates delegation.
Save Space
Chronos combines binocular autorefraction and keratometry measurements with binocular subjective testing and visual acuity in a single instrument that occupies minimum space. Chronos reduces the number of conventional refraction lanes and additional refractometers needed.
Grow
Chronos offers the versatility critical for growing your practice.
*Refraction time can vary by patient.

Topcon Announces the US Launch of Chronos
Topcon Chronos is a complete digital refraction solution that combines autorefraction, keratometry, and subjective refraction in a single device that occupies less than four feet of space. The fully automated system, which features the guided refraction software, SightPilot®, can be easily operated by anyone in the practice. Furthermore, binocular testing means refractions take just three and a half minutes*, allowing eye care providers to see more patients and grow their practice without adding exam lanes or trained technicians.

- The conversion value with “VD=12mm” is described here.
- The conversion value with the pupil power (VD=-3mm) is described here.
- The value described here is the maximum value. The measurement range is smaller according to the test distance setting for executing a test or the setting conditions of VD during measurement.
- The value described here is the maximum value. The measurable range is smaller according to the combination of the patient’s PD and the test distance.
- 0.1 – 1.6 complies with ISO 10938
