Vivior is a Swiss digital health start-up founded in 2017 by a group of experienced eye care professionals. The company develops a novel wearable device to objectively measure patient’s behavioral data prior to vision correction interventions. The system collects daily activity data from patients, processes these data in the cloud and analyses patient’s lifestyle patterns using machine-learning algorithms. This ground-breaking combination allows to better understand patients’ needs and enables eye care professionals to offer optimal personalized solutions to their patients.

Patient lifestyle data that you can trust

Currently, cataract and refractive surgeons rely on personal information about visual behavior communicated by patients either verbally or in written form. The information provided through these surveys may be misleading due to what is known in psychology as Memory Bias. In addition to anecdotal information, the Vivior Monitor combines data from the patient’s behavior with objective measurements. The patient wears the device during the testing period, and the Vivior Monitor captures information about daily activities, e.g. working on a computer, tablet, smartphone, gardening, driving, and so on.

Optimize outcomes based on individual patient’s needs

The Vivior Monitor consists of sensors measuring distance, ambient light and color, an accelerometer, a gyroscope, and a magnetometer. The Vivior Monitor does not include a camera or any other sensors which might infringe the privacy of the patient or other people.

It is worn on prescription or clear glasses. Clear spectacles are provided in the package. The recorded data are uploaded to the cloud when the system is returned for processing and analysis. Sensor data are converted into patient behavioral data using state-of-the-art artificial intelligence algorithms and provided to the surgeon in the form of intuitive visuals. The sys- tem also provides the surgeon with a patient report so that the surgeon can educate the patient during the pre-op plan- ning discussion.
