An Explorative Pilot Study of a New Mobile Phone Application Measuring Eye Parameters of Eyes in Patients With SUD

A Second Explorative Pilot Study Evaluating Usability and Functionality of a New Mobile Phone Application Measuring Eye Parameters of Eyes in Patients With Confirmed Substance Use Disorder (SUD)

This will be a pre-market, explorative, early feasibility, pilot, controlled clinical investigation designed to collect initial clinical data for Previct Drugs.

This second early feasibility study will give valuable information on the usability of Previct Drugs once being used in the intended population, i.e, patients with confirmed Substance Use Disorder (SUD). It will also give valuable information on the feasibility of Previct drugs function to measure pupils and eye movements in this population including evaluating the safety when using the device.
